FH & FIH Series (Interchange with Snap-Tite H & IH Series)
FH & FIH Series Quick Disconnect has provided years of reliable service on hydraulic/pneumatic applications in the handling of gases and flu-
ids. The FH & FIH Series couplings are engineered to meet or exceeds MIL-C-51234. Options are available for static pressure hydraulic systems and also for pneumatic air tool use.
Type:
• FH – Two Way Shut-Off and Straight-Thru
• FIH – One Way Shut-Off Interchangeability:
• FH Series interchanges with Snap-Tite “H” Series.
• FIH Series interchanges with Snap-Tite “IH” Series.
• Within each series, only sockets and plugs of the
same size will couple together.
Operation: Manual – Socket sleeve must be manually retracted to connect and disconnect.
Options: Ball Lock (BL prefix) – Locks against accidental discon- nect. To connect align ball with slot. After connection, rotate sleeve to lock. To disconnect, realign ball with slot and retract sleeve.
Seal Compound: Standard seals are Buna-N.
Rated Pressure: Rated Pressure as defined by ANSI/B93.2 –
1986, non-shock service.
Socket Features:
• Latch Mechanism
- Manual connect and disconnect
- Sleeves are hardened to provide maximum service life
• Material and Finish
- Machined from solid bar stock
- Steel components are zinc plated
• Coupled Seal
• Valved units incorporate a Teflon back-up ring to with-stand
dynamic impulse
Plug Features:
• Machined from solid bar stock
• Steel plugs are hardened and zinc plated to provide heavy
duty performance
• Flow - Large diameters provide for higher flow than other
double shut-off quick disconnects
• Seals
- Buna-N (Nitrile) seals are standard
- Valve seals are crimped in place to maintain integrity
during excessive flow conditions
