Milton's 1/2" NPT Standard Pressure Regulator is the relieving type which offers stable downstream air pressure over a wide range of air flows with accurate control, fast response, and minimal pressure drop. Regulators should always be preceded by a filter to eliminate damage to the unit or inaccurate air flow. The aluminum die cast body comes with a balanced piston, molded rubber seat, Buna-N diaphragm and O rings. This regulator also has two offset 1/4" gauge ports which can serve as two 1/4" supply lines. As a standard pressure regulator, the 1/2" NPT Regulator has a maximum inlet pressure of 250 PSI with a regulated pressure range of 5-125 PSI.
