IC1212 Insert grey Fitting Coupling 1/2" x 1/2"

This valved outlet air assembly is used when operating two pond diffusers from a single rotary vane compressor. This helps control air flow to diffusers, dissipate heat from compressor before the air tubing and also includes a pressure relief valve to protect the compressor if airlines become kinked, plugged or frozen.

Check valve assembly for rotary vane compressors installs on the inlet side of the unit between the compressor and air filter. This helps prevents back flow of water in air lines if the unit happens to turn in reverse.
