Snap-tite H Series Couplings are best suited for general purpose, hydraulic, or pneumatic fluid applications and a variety of media where either single or double shut-off valving is desired. These couplings are proven through years of use and are available in a wide range of sizes, materials, and end configurations.

Snap-tite H Series Couplers (hydraulic, fluids) up to 11,000 psi connect with Snap-tite H and PH Series Nipples. These original Snap-tite H Series quick disconnects are truely multi-purpose. 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.

Technical Characteristics:
- Sizes: 1/4” – 4”
- Materials: Steel, Aluminum, Brass, 316 Stainless Steel
- Port Ends: Male NPT, Female NPTF, Female SAE, Male SAE 37 degree Flare
- Seal Options: Nitrile, Fluorocarbon, Ethylene Propylene

Markets:
- Industrial
- Construction
- Oil and Gas
- Agriculture

Features/Benefits:
- Original Snap-tite H Series multi-purpose coupling, widely used in varied applications
- Widest range of sizes up to 4"
- Couplers and nipples are compatible to connect with or without valves, in any combination
- PH Series connect under pressure version allows connection of lines with residual pressure caused by thermal expansion
