General Purpose, Hydraulic Quick Couplings - H Series

H Series Couplers (hydraulic, fluids) up to 11,000 psi connect with H and PH Series Nipples. These original Snap-tite H Series quick disconnects are truely multi-purpose. H Series Nipples connect with H and PH Series Couplers. With sizes up to 4”, this coupling can be valved on both sides, single shut-off, or full flow. Both male and female port ends as well as many material options and the widest range of sizes available, make the Snap-tite H Series an ideal quick connection for a variety of applications.

Double  or single shut off - Couplers and nipples are compatible to connect with or without valves, in any combination.

Full flow option - Rated for pressure ranges up to 11,000 psi max when used as a straight through, unvalved connection where both coupler and nipple are plain or without valves.

Connect under pressure option - PH Series couplers allow connection with H Series valved nipples when there is residual pressure on the PH Coupler side. It is recommended that only one half of the connection (coupler or nipple) be a PH Series, not both.
