4 Pcs 20.87'' Spray Can Nozzle Extension Hose 8 mm Undercoating Spray Gun Flexible PVC Hose for Vehicles Cars Trucks

These work with the InoKraft undercoating gun sold on Amazon. Good spares to have on hand. 10mm X 1 thread size. They are just slightly smaller in diameter than the ones that come with the InoKraft but still too large to go in door drain holes.

Just as advertised. They fit a 10 mm threaded air nozzle.

Bought these to use with a TCP global undercoat gun, also found on Amazon. Tip does not thread into either gun (standard or professional version, I have both), so I removed the aluminum tip from the gun, drilled and tapped it and it fits these extensions now. For anyone looking to do the same, I used a 23/64 bit to bore out the barrel and threaded with a 3/8-24 tap. Have not used the extensions yet.

Reaches difficult spots where rust can start.

Three stars only because the listing photo is deceptive, although getting a sprayer for $16 does seem too good to be true. The extension hoses themselves are great.

Seams to function correctly. Fast shipping.

AAA+++

I haven't used these yet, but they fit my spray gun perfectly. They are priced very reasonable and I look forward to using them for getting inside hard to reach places when I undercoat my truck.

Does not include the gun

Using with a Raptor Liner Schutz gun. As other reviewer posted: I used a 23/64 bit to bore out the barrel and threaded with a 3/8-24 tap.

Too expensive for what it is. My fault ordering them
