Why this coupler
- Snap-Tite “H” interchange — which means it couples with the widely used Snap-Tite H-style hydraulic/pneumatic fittings.
- Meets or exceeds MIL-C-51234 — which means military-grade reliability for demanding gas and fluid applications.
- Higher flow than typical double shut-off — which means large internal diameters deliver more flow than comparable double shut-off quick disconnects.
- Machined from solid bar stock — which means strength and durability; steel parts are hardened and zinc plated.
- Two-way shut-off socket — which means the valve seals at disconnect to prevent fluid loss; a Teflon back-up ring withstands dynamic impulse.
Frequently asked questions
What does this connect to?
It interchanges with Snap-Tite “H” Series — only same-size FH sockets and plugs couple together.
What pressure is it rated for?
Rated to 3000 PSI (brass, 1/4″), per ANSI/B93.2 non-shock service.
Is it military spec?
Yes — the FH Series meets or exceeds MIL-C-51234.
Ideal for hydraulic systems, pneumatic air tools, and gas/fluid handling where high flow and reliability matter. Pair this coupler with a matching 1/4″ FH (Snap-Tite H) plug.
