One Way Shut Off

These couplings have a shut-off valve in the socket half (female) only which prevents fluid loss on the supply end of a line. The plugs (males) are normally un-valved.  One way shut off couplings are commonly used in pneumatic applications and for breathing air lines.

Brands include Hansen, Cejn, Rectus, Foster, Coupleurs Gromelle, Snaptite, Tema, Parker and Legris.

Rectus 21 Series - Rectus 21 Series are the worlds most popular mini industrial coupling and are suitable for liquids and gases. Diameters are only 16 mm and airflow is surprisingly high. 1/8 and 1/4 inch BSP connections male or female thread as well as hose barb connections. Valves in the coupling (female) prevent fluid loss. Construction is nickel plated brass.

Rectus 21 Series Colour Coded Couplings.

In addition to the standard Rectus 21 coupling type, there is also the option for this series in a colour coded system to avoid mix ups between media.

The mechanical coding of the female coupling and the male probe offers a guarantee for avoiding mix-ups between media when connecting, which is complemented by the colour coding of the anodised sleeves. 

A double shut-off version is also available on request.

These industrial interchange couplings are durable Hansen air couplings available in 3 different body sizes (1/4, 3/8 & 1/2"). The sockets (females) have valves to prevent fluid loss and are constructed of brass with heavy duty steel sleeves. The plugs (males) are available mainly in steel with some brass available. The 1/4" size is also available in stainless steel. Hansen Series 1000 (1/4" body), Hansen Series 400 (3/8" body) and Hansen Series 500 (1/2" body).
Sockets (females) from this Hansen series are made entirely from brass. They feature push to connect one hand operation. Four different body sizes are available (1/4, 3/8, 1/2 and 3/4") with connections up to 1". These couplings are mainly used for compressed air but they will also handle other fluids and gases. Hansen Series 3000 (1/4" body), Hansen Series 4000 (3/8" body), Hansen Series 5000 (1/2" body), Hansen Series 6000 (3/4" body).

Hansen Series RL 'Ring Lock' couplings are heavy duty pneumatic couplings. These Hansen RL series couplings will not disconnect when dragged along the ground and often used on pneumatic tools in the mining industry.

Rectus 33KA series (single shut-off) is an industrial coupling with Atlas Copco profile QIC10 NIP10. Specially suited for use with gaseous media in industry. Single hand push-to-connect.  UltraFlo valve for optimum flow and low pressure drop.
35 bar working pressures (with 4:1 safety factor).
Coupler is brass/steel nickel plated.
Probe is steel nickel plated.
Made in Germany.

CEJN Multi-Link outlets

Safe and organised workspace with compressed air multi-outlets with unrestricted flow - powered by CEJN eSafe couplings.

The Multi-Link integrated quick connect couplings come in units of 1 to 5 outlets. 

The units can also easily be connected to create more access points. Ideal for uncluttering existing work areas or to create new flexible work stations. 

The integrated couplings provide flexibility and high performance, the design allows for a large number of outlets without restricting the flow with T-connections, bends or elbows. 

In combination with CEJN high quality polyurethane hose it becomes a flexible high performance air distribution system.

These versatile units save space, time and energy.

Convenient access to the compressed air power source.

180-degree outlet independent swivel prevents hose kinking.

Easier installation with fewer components to install.
