Why this plug

  • 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.
  • Unvalved straight-thru plug — which means full flow; works with both FH straight-thru and FIH sockets.

Frequently asked questions
