SMC check valve


 Product Description


SMC 3/8 NPT check valve.  AK4000-N03

SMC 1/2 NPT check valve. AK4000-N04 

Use in conjunction with engine driven compressors to prevent pressure from leaking back through the head. Mount as far from the compressor as possible for best results, and ahead of the moisture trap so that it stays pressurized for draining.
