Snap-tite H Series couplings have been proven by years of use
on hydraulic applications.
H Series is best suited for general purpose fluid applications
where either single or double shut-off valving is desired. A wide
range of sizes, materials and end configurations are available.
PH version couplers and nipples are valved with a connect-
under-pressure feature. These steel couplers and nipples
allow connection with H Series valved couplers and nipples
when there is a residual pressure on the PH coupler/nipple
side. It is recommended that only one half of the connection
(
coupler or nipple) be PH version, not both.
Features:
•
Sizes 1/4” - 4”
•
Available in steel, brass, aluminum and 316 stainless steel
•
Standard seal material is nitrile with other options available
•
Optional sleeve lock helps to prevent accidental
disconnection
•
Double-shut-off version has low pressure drop
•
Manually operated sleeve provides secure connection

NOTE:
Pressure ratings were established under static pressure conditions. Therefore, pressure ratings for any given flow, pressure surge and/or vibration may vary from
these ratings. 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.)
Applications include:
•
Industrial hydraulic lines
•
Water and coolant lines
•
Mobile equipment
