Parker’s 71 Series, formerly known as Snap-tite couplings, are engineered for high-pressure applications with working pressures up to 10,000 psi. Designed with flush-face valves to minimize air inclusion and fluid loss, these couplings offer clean, efficient operation. Available in a range of materials and body sizes, the 71 Series features large flow chambers and a unique valve design that delivers exceptional flow capacity while keeping pressure drop to a minimum—ideal for demanding hydraulic systems that require reliable, high-performance connections.
