Snap-Tite 75 Series and 59 Series hydraulic couplings

Snap-Tite’s 75 Series and 59 Series couplings are designed for high-pressure hydraulic service.

The 75 Series couplings are engineered to be used in heavy-duty applications with mobile equipment, oil and gas drilling, cranes, reels, pumps and power tools as well as water transfer lines and power units. Connection is through a screw-together style designed to shut off automatically under normal conditions in both the coupler and nipple halves when the unit is disconnected.

The rugged design and high-strength materials mean the units can be used in abusive situations. Units are available in stainless steel or steel with zinc trivalent chromate plating that resists corrosion. A choice of seal materials means the 75 Series is able to handle a variety of applications including the use of fire-resistant fluids. Snap-Tite Series 75 are available in Firesafe versions as specified in API 160 and EUB directive #36 for use of blowout prevention (BOP) circuits.

Series 59 is a thread-to-connect quick-disconnect coupling that allows connection and disconnection while under pressure due to its threaded design and patented internal valve system. Suitable for any pulsing or hammering equipment, an optional snaplock feature is available if pulsating flows tend to unscrew couplings due to hose flex. Backpressure is low and heat generation is kept to a minimum. The coupling is a no-spill, drybreak, flat-faced design that keeps the workplace free of spillage.

The unique Acme thread fully connects in one-third the turns of similar couplers while remaining dirt tolerant.
