R-12 and R-134a conversion adapters

R-12 and R-134a conversion adapters by Yellow Jacket convert existing R-12 charging hoses over for use with R-134a systems. The adapters include high and low side quick couplers, a common service hose and shutoff valves to prevent the release of refrigerant. Shutoff valves will attach to any 1/4" SAE female flare fitting. The adapters have six balls inside the coupler to keep the coupler tight on the service port. Each hose is approximately 8" long.
