1" impact coupling

[Firewoodjoe]

I just bought a 1" impact and half in line I want 1/2" pipe thread couplings. Would hydraulic couplings work? I have them.

[cutter88]

Would work... I think

I think i have 3/4 line going to 1in impact gun  :-\

[Firewoodjoe]

Your saying the half isn't big enough? I think it has half npt on the gun. Maybe not. I'll check.

[Firewoodjoe]

Yeah it's 1/2-14 NPT

Just because the impact has a 1/2 inch fitting doesn't mean a 1/2 inch line will supply enough volume. A 1/2 inch line will work but to get the full potential of a 1 inch impact it should have a 3/4 inch line.

Yep, definitely  use 3/4 to get maximum torque.

[Firewoodjoe]

Ok. Well they didn't have a 3/4". I'll have to find one if it don't work good.

I use 1/2" hose for the 1" gun, it works perfectly.

I have 4 set ups using 1/2 " coupling  and 1/2 " air line and have never had a problem using them but I am using high CFM air compressor also.
