The Ralston Quick-test Hose Adaptors provide a fast, pressure-tight connection between Ralston Quick-test™ hoses and pumps or any Ralston Quick-test™ fitting. Designed for convenience and reliability, these adaptors use a finger-tight connection, eliminating the need for Teflon tape. For best results, a small amount of oil or grease can be applied to the adapter end before attaching to the hose to ensure a secure and leak-free fit.
