H, IH & PH Series -- Couplings for Hydraulic,
Pneumatic and General Purpose Use
Pneumatic and General Purpose Use
Sizes —
1/8” – 4” Metals
— H Series Quick Disconnect Couplings are available in four metals
– steel, brass, aluminum and 316 stainless steel. A variety of protective
finishes are available. Seal
Versatility — Wide choice of standard and special seal materials
enable the H, IH & PH series to handle a great variety of fluids. Sleeve
Lock — Sleeve lock option aids in preventing accidental disconnection
of the coupling. To disconnect, align the pin in the body with the slot
in the sleeve and retract sleeve. (Valve
& Valve) Quick Disconnect Low Pressure Drop — The two-piece
body construction permits larger flow passages than the designated size
of the coupling, permitting greater flow while maintaining low pressure
drop and provides end fitting versatility. 
Smooth Flow — Snap-tite’s “Jet
Stream” valve design helps maintain a clean linear flow. Positive positioning
of the valve aids in maintaining a steady, even flow under normal working conditions. Flow
on Connection — Valves are designed to automatically open
in both the coupler and nipple halveswhen the unit is connected permitting maximum free flow.
Shut-off
On Disconnection — Valves are designed to automatically
close under normal usage conditionsin both the coupler and nipple halves when the unit is disconnected.
Fast
Efficient Operation — Connect or disconnect in seconds.
To connect, pull back the sleeve, insert thenipple into the coupler and release the sleeve. To disconnect, pull back the sleeve, remove the nipple and the halves are disconnected.
Dependable
Operation — Ball-lock mechanism provides positive connection.
Hardened stainless steelballs along with a radiused and induction hardened (steel) ball race gives extended life to the H Series couplings.
Positive
Sealing Connected — Two types of seals are available with
H Series quick disconnects.Molded U-Packer Seal – Standard for all sizes; provides contact over several times the normal O-ring sealing
area. The unique U-packer seal design embodies a self-energizing feature that permits a positive seal at all
pressures. The design also enables the coupling to seal under adverse conditions such as side load, scratches on the nipple from usage abuse or dirt on the nipple.
Optional
Seal (-9) – Can be supplied as standard in place of the
U-Packer seal in steel and stainless steelconstruction in sizes 1/4” thru 1-1/4”. Designed for use with high pressure, multiple-cycle hydraulic or
pneumatic applications, the seal set consists of a standard O-ring and a Teflon back-up ring. This seal
configuration prevents the seal from extruding under multiple-cycle high flow and pressure surge applications.
Positive
Sealing Disconnected — The metal to metal contact of the
valve with the coupler or nipplebody is designed to control compression of the valve seal eliminating wear and increasing seal life.
Pressure and Flow Data
Pressure ratings of standard quick disconnects can be increased for some applications by slight design modifications or if specific operating conditions are met. On applications requiring higher ratings than those listed or pressure surges, please consult Knight Hawk Supply. Burst pressures listed were taken at the point at which failure rendered the quick disconnect inoperative. (Proof pressure equals 1-1/2 times the working pressure; burst pressure equals 2 times working pressure.)
*For Det Norske Veritas (DNV) compliance, divide the working pressures shown by 2.
