Triclover clamp thread size 1.5"

[Mattblock]

I am trying to determine what size the threads are for a 1.5" triclamp. Not around my measuring tools so unable to self determine.

a 1.5" triclamp fitting fits a 1.5" stainless tube, meaning that the outer diameter of the tube is 1.5"
The actual ferrule (triclamp end) is close to 2" in diameter.

The same size ferrule is used in a 1" triclamp, but the tube is 1"od. if you order 1"od triclamp gaskets they will fit a 1.5" triclamp but the hole in the middle is smaller.

you can get different tube wall thicknesses for different applications.

Pipe thread (NPT= national pipe taper) refers to the inside diameter of the pipe, so according to the chart below 3/4npt is 1.050" outside diameter.

check with gwkent. they have good info on this as well.

If you mean the threads on the clamp itself, they are 5/16" X 18 tpi on most clamps. Some of the super-heavy-duty clamps--with nuts and bolts instead of wingnuts--can go to 1/2" X 16 (?) tpi.
