Description:

The CTB has a female inlet and a male outlet. Inlets range from 1/4" to 1-1/2"(FPT). Outlets range from 1/2" to 1-1/2" (MPT). Has optional 1/8" unloader port on hex section. Check valves control the flow of air into the receiver tank. When the compressor reaches unload pressure the check valves closes, preventing the backflow of air from the receiver tank into the discharge supply line. To figure out what size you have, measure the OD of the fitting that fits into the check valve.

This is a handy chart below.
