Snap-tite H, IH & PH Series General Purpose Hydraulic and Pneumatic Quick Couplings Many Standard Configurations Suitable for Hydraulic and Pneumatic Applications: Snap-tite H Series couplings have been proven by years of use on hydraulic and pneumatic 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 residual pressure on the PH coupler/nipple side. IH version couplers are steel with a cylindrical valve designed specifically for pneumatic use. When paired with an unvalved/plain H Series nipple, it functions as a durable single-shut-off connection. Contact Information: Parker Hannifin Corporation Quick Coupling Division 8145 Lewis Road Minneapolis, MN 55427 • Sizes 1/4"-4" • Available in steel, brass, aluminum and 316 stainless steel • Seal material options available • Optional sleeve lock helps to prevent accidental disconnection • Double-shut-off version has low pressure drop • Manually operated sleeve provides secure connection

Technical and Dimensional Information H Series couplings are suitable for general purpose applications and a variety of media. They are very versatile in material, size and end configuration. Valve combinations include: - Double shut-off poppet valves - Single shut-off on the coupler or nipple side - Straight through (unvalved/plain) Postive Ball-Lock Design Two -Piece Body Construction PH version couplers and nipples make it possible to overcome the high connection force caused by residual pressure. The poppet valves have an added pressure relief feature to allow connection under static pressures...
