Aluminium Cam-and-Groove Coupling

The Value Brand 3LX44 is a 3-inch Type B socket made from aluminium. It accepts a 3-inch male hose fitting on one side and a 3-inch NPT male thread on the other. The coupling is rated for 125 psi at 70 F and includes a nitrile gasket and a locking arm for secure closure.

Nitrile Gasket and Locking Arm

The supplied nitrile gasket provides the seal between the socket and the mating adaptor, while the integrated locking arm holds the cam levers in the engaged position. These items arrive fitted, so no separate sealing or retention parts need to be sourced before installation.

Thread and Hose Compatibility

Verify that the mating component has a 3-inch NPT male thread and that the hose or pipe end matches the 3-inch hose fitting size. The socket inside diameter is 3 41/64 inches, so the male adaptor must fit within that dimension. Check that the system pressure does not exceed the rated limit.

Questions about this item

How often should the nitrile gasket on this 3 in coupling be inspected or replaced?

Inspect the nitrile gasket each time the coupling is disconnected; replace it if you see cracks, hardening or deformation that could prevent a seal at 125 psi.

What pressure limit governs continuous operation of this aluminium Type B socket at 70 F?

The maximum working pressure is 125 psi at 70 F; sustained service above that rating can cause leakage or body deformation.

How hot does the aluminium body get when fluid runs at the 125 psi rating all day?

Aluminium conducts heat quickly, so the body temperature will closely match the fluid temperature; no separate heat-rise figure is published for this coupling.
