Designed for easy cutting and tool-free assembly, it offers flexible bending with a 6-8 inch radius, scalable outlet options, and durable corrosion-resistant materials, making it the ultimate upgrade for professional shops and serious DIYers seeking efficient, clutter-free compressed air distribution. ## Description Set up a compressed air system with the 3/4-Inch Maxline Master Kit with 3 air outlet locations. The Maxline tubing has an aluminum core sandwiched between an inner and outer layer of polyethylene. Tubing can be mounted on wall surfaces, in wall, or buried underground or concrete. Tubing holds any hand bent shape. Reduce shop clutter with this industrial compressed air piping system. No glue, soldering or crimping needed. Simply cut the tubing to length, insert in the fitting and tighten. Easy to expand with more air outlet locations or modify later. Review: I was a little suspicious when I initially ordered, but seemed like a better way to go than piecing together black pipe or rubber lines. Wasn't disappointed at all, stuffs awesome. The lines themselves are weirdly rigid while being easily formed to take turns or go around obstacles. I had one large 25 foot run behind conduits and other stuff on the wall I was worried about, simply cut the length I needed and pulled/pushed the line through in all of 2 minutes. The fittings are solid, machined aluminum with brass plugs and a drain spout. I'd rate the machining as consumer grade, there are areas where edges are milled down right beside edges that aren't. Mind the utility parts are great, threads are clean and there's no burrs or anything I needed to take care of ahead of time. Seems most people wind up with more line than fittings, which is smart for the company and easily solved by the consumer (I'll be it at a cost, the fittings are expensive). But the fittings it comes with are enough to get you started, and the quality and convenience of everything included makes up for having one less fitting than you'd want. Review: Although I've only had this system installed for a week, I'm tentatively giving it 5 stars. Purely based on other reviews I have some concerns for down the road, but right now everything seems really, really nice. Based on questions people have asked and some other reviews, let me throw some stuff out there: The 3/4" tube is a little cumbersome to uncoil. You can make the machine on rapidair's website or something similar, but I had no problems getting the pipe pretty darned straight. My install consisted of several ~15' runs, the longest was 25'. I had a helper hold one end of the coil and then walked it out, holding it down with my feet as I walked with some really cushy flip flops. The end result was a *really* wide arc that was easy to straighten by hand. It was not a big deal. I measured out each segment, then cut a length of the straightened pipe adding about a 1' for slop & mistakes. I planned so that each segment would only have one angle to avoid frustration. Starting with the longest straight, I connected the pipe to whatever fitting was there (sometimes a tee, sometimes an outlet) and then walked the pipe into the corner, forming it by hand as I went. Once it was roughly in the right place, I installed one of the pipe clips to keep it in place, then laid out the other leg of the run. Aside from the straightening, I laid 90' of this by myself without help. It's not tough. Pro Tip: Read the directions. They are explicit and on-point. All NPT fittings should be wrapped with two wraps of Teflon tape. All NPT fittings should be doped (although I prefer Permatex High Performance Thread Sealant). Build the outlets (plug, M8005 fitting, 50120 drain, and air fitting of your choice) in ADVANCE. Install the outlets IN ADVANCE. No treatment (tape or dope) is required on the Maxline pipe fittings - the O-rings seal them, not the threads. As such, when cutting the pipe, it MUST be STRAIGHT, a perfect 90 degrees, and you must use the reamer to make sure the pipe is round (not ovalled) and properly beveled. Otherwise it may not seal properly on the fittings. Leave some extra when measuring the pipe in case you need to re-cut! If I have any complaints, it's that the cutter they supply is difficult to use - the "mouth" should be 2-3" wide to ensure a good, straight cut. Oh well! Finally, do not try to assemble the M8005 fittings onto the pipe first. They are not swivel fittings. The NPT side of the fitting must be installed first, then install the pipe onto it. When you finally assemble the pipe onto the M8005 (last step!) be sure you tighten the collar at least 3/4 turn. There seems to be some confusion about the three #M81010 outlet blocks that come with this kit. Each outlet has three ports - the top, back, and front part are all 1/2" NPT. The idea is to connect the pipe to the outlet at the TOP or BACK (such as through a wall) and then use the NPT plug to plug whichever one you did not use. Three outlets = three plugs. You could use the other port to "daisy chain" to another outlet, but that would be awkward. The front port is for your tool or a quick-disconnect but, again, could be used to daisy chain. I used Dixon Valve DC2504 (from desertcart) as they are 1/2" NPT -> 3/8" (industrial-style, there is an automotive style equivalent) quick disconnect, so no adapters needed. You can use Dixon Valve DCP2103 on your tool - it's a matching 3/8" quick disconnect with a 1/4" NPT. Easy! The bottom port is 3/8" NPT and is *intended* to house the drain valve. This makes it easy to depressurize the pipe system and drain water that *will* accumulate in the outlet. You *can* use this port to daisy chain or connect tools, but it's *supposed* to be a water drain. Three #50120 are included with this kit for this purpose! I ordered an extra tee (#M8011) with this kit with two purposes in mind: It broke up what would have been a very long (40'), very cumbersome run of tube *and* provided a space to mount an overhead hose reel. Plugging in and storing a hose would have been annoying, so I just installed an overhead reel permanently. #M8005 goes straight from the 3/4" pipe to a 1/2" NPT thread. I picked up a 1/2" NPT shutoff valve (in case I need to remove the hose for some reason, and so the hose doesn't have to hold 90psi all the time) but no quick disconnect to remove a restriction point. The hose connects directly to the shutoff valve. Easy! (Remember, assemble backwards - reel to shutoff valve, shutoff valve to M8005 fitting, *then* M8005 to pipe!) My final install looks like: Big ol' 80 gallon compressor -> shutoff valve -> flexible jumper (ALWAYS CRITICAL) -> PneumaticPlus SAU4020M-N06BG (filter/regulator) @ 100psi -> pipe system. The pipe system has essentially four legs - one goes from the garage into the shop (through a wall), one goes to two outlets on opposite sides of the garage, one goes to the second shutoff valve & overhead reel, and one goes to an outlet on the back wall, incorporating a SECOND regulator/filter for paint. I'm really happy with this, and really happy I dragged my feet on this purchase for years. Rapidair has a complete setup here, with all the parts & pieces you need to fully customize your solution. Six days later I have seen no leaks anywhere - and I'm literally itching to use my bigger air tools! :) I have yet to see whether the pipe will take a hit (it's on walls and in rafters, so hopefully it won't have to!) and what happens over time... until then, 5 stars! ## Features - EASY INSTALLATION – From the moment you start operating our industrial quality compressed air piping system you will enjoy its trouble-free safe operations. But first, you will like the easy installation of our air compressor hose kit. Just have a plan as to the location of the air compressor and where you are going to mount the compressed air outlets, follow the step-by-step instructions we provide, and very soon you will have it seamlessly up and running. - NO LEAKS AIR SYSTEM – We offer a complete leak-proof compressed air supply solution for your shop or a garage, rolling up to 100 ft. Smooth interior walls of our piping rolls will never build upscale or rust. It is much more efficient than iron or PVC piping, and while reliably holding pressure, operates at 200 psi at 73F and 160 psi at 140F. - EASY TO CUT AND TERMINATE – No more pipe cutting, messy threading, or gluing! We provide you with a simple tool to make it effortless. MaxLine Master Kit has all components necessary to complete the installation. - BENDABLE AND FLEXIBLE - What a relief if compared with iron, copper, or PVC piping! Rolls with fewer joints allow not only faster installation but also make it easy to bend and keep in place. The aluminum lining of our rolls can create rigid but flexible layouts. The 3/4-inch inside diameter of the pipe has a bend radius of 6-8 inches and can be bent to any shape. - SCALABILITY – Perfect for shops or garages of any size and layout. You can purchase additional accessories if necessary, to expand or further customize your pneumatic line installation based on the requirements of pressurized air distribution. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005FKYRTU | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 1,295,595 in DIY & Tools ( See Top 100 in DIY & Tools ) 7,604 in Air Tool Accessories | | Colour | Blue | | Customer Reviews | 4.6 4.6 out of 5 stars (870) | | Date First Available | 20 Nov. 2012 | | Item Package Quantity | 1 | | Item Weight | 9.07 kg | | Item model number | M7500 | | Manufacturer | Rapidair Maxline | | Material | High Density Polyethylene | | Maximum Pressure | 175 Pound per Square Inch | | Number of Pieces | 1 | | Part Number | M7500 | | Product Dimensions | 53.34 x 53.34 x 20.32 cm; 9.07 kg | | Size | 3/4" x 100' | | Style | Master Kit | | Voltage | 1 Volts | ## Product Details - **Brand:** Maxline - **Colour:** Blue - **Connector type:** Compression - **Exterior finish:** Aluminium - **Item dimensions L x W x H:** 53.3 x 53.3 x 20.3 centimetres - **Item weight:** 9.07 Kilograms - **Material:** High Density Polyethylene - **Size:** 3/4" x 100' - **Thread size:** 0.75 inch - **Thread type:** NPT ## Images ![Maxline M7500 Master Kit, 3/4-Inch x 100-Feet by Maxline - Image 1](https://m.media-amazon.com/images/I/41Fp96zkWrL.jpg) ![Maxline M7500 Master Kit, 3/4-Inch x 100-Feet by Maxline - Image 2](https://m.media-amazon.com/images/I/71O7IHJ51AL.jpg) ## Questions & Answers **Q: Is the 3/4 the i.d. or the o.d.? What is the o.d.** A: The tubing in the 3/4 Maxline M7500 master kit is .80 inch inside diameter x 1.00 inch outside diameter **Q: I have 175 psi. The mfg recommends keeping the system at 175 psi and the regulating the pressure where needed. Will this stand up to that?** A: Yes, the system is rated for 200 psi. For any air system, its best to regulate the air system to 100-120 psi at the compressor, with an inline regulator. Most air tools have a maximum pressure rating of 120 psi and that protects them. **Q: Will standard pex-al-pex compression fittings work?** A: Yes they will work. This line IS pex-al-pex. I have used the fittings myself so I know it works. Also, the aluminum inner sheath is the giveaway that it's pex-al-pex. **Q: Is there 3 brass plugs included for the outlets** A: You'll need something to plug one hole for each of the outlets. It does come with 3 plugs but there's a hole in the back also. I had to get more plugs for the fronts ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***E on 11 October 2018* I was a little suspicious when I initially ordered, but seemed like a better way to go than piecing together black pipe or rubber lines.
