ABST PEX Manifold,5 Loop Stainless Steel Floor Radiant Heat Manifold Kit with 1/2" Adapters Included for Hydronic Radiant Floor Heating

Works great, had a couple minor leaks, just had to snug fittings. Kept my 1200ft garage @ 70 degrees all winter with Rheem on-demand water heater.

This item goes beyond my expectations and earns 5 stars. Exactly what I was looking for. Nicely packaged with everything you need. Arrived in perfect condition. I wanted something like a in-floor heating manifold for use with cooling a Tesla battery system. Tesla Mod3 batteries come with 2 loops each, and I have 2 batteries, so 4 loops was perfect. Adjust flow on the fly and see exactly what is happening.

Just got this 2 days ago. "LOOKS" like a quality product, but we will see how it is next winter. Will install this summer. Shipping was X-TREAMLY fast and no damage!

This device is perfect for my 3 loop in floor heating system. Has adjustments to regulate the flow to each loop independently. Has relief valves and air excape valve. Had to study the directions carefully to understand how to control it. Only issue I had was a problem getting the 1 inch connection to seal. After a few trys with regular teflon, I purchased the really good stuff and it sealed. Very happy with this product.

Color me impressed, I have been installing radiant floor systems for 40 years and this is the best build & best value I have seen! The only issue was the 1” threads on the ball valves didn’t seal well with Teflon tape, had to use Teflon thread dope. I suspect that Chinese NPT is slightly different.

works great! Have this running a radiant system in a 30x30 shop and does an amazing job!

Very nice set up. But either my mistake or Amazon didn't have floor radiant heat only. Brought for home use. The flow is too restricted for home use. Ordered the other for home and did not come with all this has. Like mounts and everything needed. All in all huge Amazon fail.

Very nicely made manifold for the cost. Worth 2x+ what it priced at. BUT …. The female 1” connection threads don’t quite meet the USA national pipe thread dimensions and consistency Leak. This occurred on three different sized manifolds no matter how tight you take it and under low pressure. Fittings were carefully Teflon tape wrapped with thicker gas tape and leaked. I disassembled and cleaned, rewraped with tape and then wiped with teflon paste. This occurred 3 out of 4 fittings. BE Sure to tape and paste on all these st steel manifolds forming China.

I was slightly worried about the quality of the manifold and how compared to the brand name models. While I haven't used brand name manifolds, I was very impressed by the weight and quality of this manifold. The adjustment knobs work great and allow for fine adjustments. They even allow for full blocking of some loops. My system only has 9 loops and I was planning to install a short stub of PEX with a plug as insurance if the valves failed or had a slight leak, but I have yet to go back and do it and there are no leaks.

Très bon produit, je suis vraiment satisfait! J’ai installé plusieurs systèmes de chauffage au Glycol et ce collecteur est de bonne qualité à un prix raisonnable.

This is a great manifold at a very reasonable price, compared to what you’d pay for a brand name one. My first one arrived with one of the red collars cracked so I exchanged it for a new one through Amazon. The plastic on the red collars does seem a bit brittle so I can see how that would happen, but they’re mostly decorative anyway. It was a bit tricky to seal the 1” NPT threads on the input and return (as others have said) but even the more expensive brand name ones suffer from this issue. I just went 25 to 30 wraps of teflon tape around it and it’s held just fine. Otherwise the manifold works just as well as a brand name one and has all the same features (for a fraction of the price). A great buy!

Absolutely perfect
