Connection
Crystal CPF System: Medium Pressure Female (MPF) (1/4” medium pressure tube system with
7/16-20 threads). See Crystal Engineering’s CPF Brochure for further information.
CPF o-ring size and material: AS568A-012, Viton 90 durometer.
CAUTION: To achieve CPF maximum allowable working pressures no o-ring substitutions
are allowed. See Crystal Engineering’s CPF brochure and CES-003 CPF Safety Guide avail-
