Highest Pressure Connections
With max pressure ranges well over 5,000 psi, Ralston Quick-test™ connections out-perform the competitor's quick connect and adapt to all standard connections.
Up to 6,900 PSI
Up to 10,000 PSI
Make direct, live pressure connections up to 3,000 PSI instantly
For faster connections with a device under live pressure, use Quick-test fittings and adapters with the integrated check valve. Connections can be created and disconnected without needing to vent and re-pressurize. Use a cap and chain for permanent installation.
