Collection: Couplings & Joiners

The most common ranges of couplings and joiners all in one place. Looking for something that isn't here? Give us a call — we stock other specialist couplings and fittings not listed here.

What's in the Range:

  • Camlock Fittings: Quick-connect couplings in aluminium, polypropylene and 316 stainless steel. The most versatile option for general fluid transfer.
  • Bauer Couplings: Heavy-duty couplings for large suction and layflat assemblies. Connect at an angle and still hold a watertight seal — the standard for high-volume water transfer.
  • Claw Couplers: For compressed air and pneumatic systems. Surelock, Type A and Type B variants.
  • Hosetail Fittings: Barbed one end, threaded the other, for building hose assemblies onto pipework or equipment.
  • Hose Menders: Barbed both ends, for joining two lengths of hose or repairing a damaged section.

Getting the Selection Right:

  • Size by Hose Inner Diameter: Fittings are sized on the hose ID, not the outside diameter. Two 2" hoses can have very different outside diameters depending on wall thickness.
  • Match the Material to the Fluid: The coupling has to survive whatever is flowing through it as well as the environment it is installed in.
  • Check the Thread Standard: BSP and NPT threads look similar but are not interchangeable.
  • Use the Right Fitting for Air: Compressed air lines take claw couplings, not camlocks.
