Heating and Cooling - Pipe Check-

Pipe Check

Pipe Check is an easy way to check a pipe thread. This handy tool can check pipe sizes from 1/16” through 1/2” for a number of applications. Use the PC-100 to quickly find the size of a pipe.

PC-100
PC-100 simply determines the size of pipes from 1/16” to 1/2” NPT. Made entirely of heavy gauge aluminum. Just turn the thread into the hole that fits to determine pipe sizes.

The nominal size of any pipe does not in fact refer to either the outside diameter (O.D.) or the inside diameter (I.D.) of the pipe. The table lists standard pipe sizes along with the actual O.D. and I.D. for each size.

Once the correct pipe size has been determined, the “E” dimension may be used to determine the length of the component required to assemble properly when fully tightened.
