Create custom couplings to save space, adapt between varied connections, and snake around obstructions. These couplings let you mate plugs and sockets with different end styles to change the overall connection size, type, and orientation to fit your specific setup. Combine connectors with a mating plug or socket fitting to create couplings with unique shapes. Made of brass, these couplings have good corrosion resistance.

All plugs and sockets snap together with a latch and quickly disconnect when you press the latch down. This means you can reroute flow in your line with no hassle. Plugs secure with a Buna-N rubber O-ring to prevent vibrating and loosening. The O-ring also resists oil and water.

A complete coupling consists of a plug and socket (both sold separately).

Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.

Caps latch onto plugs to keep out dirt and debris.

End plugs fit into sockets to keep out dirt and debris.
