The Campbell Hausfeld 1/4 inch NPT ASME 200 PSI safety valve (GR002100AJ) is used to replace the safety valve on most Campbell Hausfeld air compressors with model numbers beginning with the letters CI, CL, EX, HS, PROV, TF or TK, such as models CI071080VMS and HS481300AJ, and on other brands of air compressors. This essential safety device activates when pressure in an air compressor tank exceeds a pre-set level, releasing the excessive pressure and protecting the tank from rupturing. Refer to your owner’s manual to see if this safety valve fits your air compressor.
