The 'Posi-Lok' couplings above all feature a 1/2" 'head' and therefore, any size male nipple above will connect any size female coupler.

'Posi-Lok' couplings will not disconnect when they are subject to hose torque, unlike standard compressor couplings, this makes them ideal for use when the hose is hand held, as is often the case with air operated tools.

We can also supply Giant and Mini 'Posi-Lok' couplings. Giant have a larger body with 1-1/4" terminations. Mini couplings have a smaller body with 1/2" ends. Our Mini's are interchangeable with those of TT Technologies and are ideally suited for moling/piercing applications. The hosetail is specifically designed to be swaged into hydraulic hose.

Many other options are also available, including a locking sleeve version, for complete safety during use.

Brass couplings for water are also available.

Ideal for use with 'Whipcheck' Safety Cables in safety conscious applications.
