Universal Leak-Proof A/C Caps for R134A Systems.
Stop refrigerant leaks before they start. A/C Quick Cap for R134A systems are the only caps on the market engineered to seal in refrigerant pressure — even if your Schrader valves fail.
Traditional plastic caps are just dust covers. Our patented quick-connect design forms a mechanical, pressure-tight seal using internal locking bearings and a high-pressure O-ring system. Whether you’re dealing with a slow leak or a worn-out valve, these caps provide a second layer of protection — saving your refrigerant, your compressor, and your wallet.
Leak-proof: tested to hold full refrigerant pressure, even with failed or missing Schrader valves
Patented quick-connect locking system installs in seconds with no tools
High-pressure O-ring seals refrigerant at the valve opening
Replaces hundreds of mismatched or hard-to-find cap/valve combinations
Durable, reusable, and technician-approved
