A/C Integrated Charge Valve - Primary Seal

The evolution of air conditioning systems from R12 to R134A in the 1990’s required a change to the air conditioning valve specification. The new leak requirement and the assembly plant’s need for higher flow while charging made necessary a valve more robust than the original Schrader Pacific design. The resulting new Primary Seal valve assembly is a 100% leak-tested, multiple poke-yoked valve assembly designed to meet the high flow and leak integrity the industry demands. This new valve is still commonly used in 1234yf systems today.

Schrader Pacific has manufactured over 12 million primary seal valves each year, with zero-defect quality. An estimated 250 million Schrader Pacific primary seal valves are currently used in air conditioning applications worldwide.
