Swing Couplings

swing coupler

TST Swing Couplings offer unrestricted full flow with safe, quick connection and disconnection under pressure. The ergonomic design provides superior sealing, ease of operation and long service life. For compressed air supply lines to pneumatic tools and automation equipment. TST Swing Couplings perform best when used with precision-made TST plugs –though, couplings are interchangeable with most plug systems.

Sizes: 1/4” (6 mm) to 3/4” (19 mm)

Quality Features
TST Swing Couplings are manufactured from select grades of ferrous and non-ferrous materials. Special surface treatment on housings and cylinders guarantee durability with little wear and high corrosion resistance.

Operating pressure up to 360 psi (25 bar) – connection and disconnection up to 200 psi (15 bar) – also suitable for technical vacuums up to approximately 3 inHg (100 mbar).

Standard model from -4ºF to +212ºF (-20º to+100ºC). Higher temperatures possible depending upon media with the use of FPM or EPDM seals.
TST Swing Couplings are fitted with nitrile elastomer seals NBR. Other seals are optional. Extra precaution must be taken with gaseous applications.
High quality silicon-free lubricant is standard.

Safety Features

Simultaneous venting, the need to hold the hose end with the plug to be removed from the coupling during disconnecting reduces whiplash effect. The orange coloring on the release sleeve signifies safety. The plastic coating affords increased grip and can also prevent damage to workpieces.

Safety standard: ISO 4414, MILC 4109


If plugs with barbed stem are used, barb stem size has to match inside diameter of the hose. Fittings/plugs must be secured to the hose with a hose clamp, preferably an TST Clamp. For chemical resistance to aggressive media, the coupling and seal components must be tested prior to use.
