Overview

Brass Hex Couplings for Air & Pneumatic Connections

A brass hexagon coupling is the female counterpart to the hex nipple. It connects two male threads, and its hex body gives a positive spanner grip that round sockets lack, which matters when holding one side still while tightening the other. On air lines it links a male hose fitting to a valve tail, extends a male port, or joins short pipe nipples into a drop leg.

We stock equal couplings from 1/8" to 1" and reducing couplings for joining different thread sizes, in BSP and NPT. Brass handles the moisture in compressed air and repeated assembly well. Reducing couplings are useful at compressor outlets, where a larger pipe thread steps down to a hose fitting. In drop legs, couplings join short nipples to ball valves and filter regulators.

FAQ

Common questions

What is the difference between a hex coupling and a hex nipple?
A hex coupling has female threads at both ends and joins two male parts. A hex nipple has male threads at both ends and joins two female ports. Together they cover most in-line air connections.
Why choose a hexagon coupling over a round socket?
The hex gives a secure spanner grip, so you can hold the coupling while tightening the second component. Round sockets need pipe grips that can mark the brass. This also protects the finish on nickel-plated parts.
What range of brass hex couplings do you supply?
Equal couplings from 1/8" to 1" and reducing couplings in common steps, in BSP and NPT threads. Plain brass and nickel-plated finishes are both available, and couplings can be matched with nipples and bushings for complete drop legs.
How much does a brass hex coupling cost in Dubai?
It depends on size, thread type and quantity. Send your list on WhatsApp for a quote. NPT and nickel-plated versions are priced separately, and workshops buying mixed sizes in bulk can request a combined price.
Do you deliver pneumatic fittings across the UAE?
Yes. We deliver across the UAE and dispatch to KSA, the GCC and Africa. Urgent orders can be collected from our store in Deira. Each size is bagged and labelled.
