Dixon Valve & Coupling Co. 5040-DA-AL Reducing Coupler/Adapter 5 x 4 in 75 psi

SKU CH-AQV8-19TZP

Aluminum reducing coupler joins 5-inch socket to 4-inch plug with nitrile gasket and locking arm at 75 psi

  • Aluminium body resists corrosion during fluid transfer
  • Reducing 5 in socket to 4 in plug connects mismatched lines
  • Cam-and-groove locking arm secures joint without tools
  • Nitrile gasket seals up to 75 psi at 70 F
  • Compact 6 11/16 in length fits tight installations

Reducing Coupler Adapter 5 x 4 In

The Dixon 5040-DA-AL is an aluminum cam-and-groove fitting that joins a 5-inch female socket to a 4-inch male plug. It suits fluid-transfer systems where a quick, tool-free connection between different hose or pipe diameters is required.

Replaces Separate Reducer And Coupling

Using this single Type DA unit removes the need for a separate reducer bushing plus a standard coupler, cutting potential leak paths and assembly time. The step-down is worthwhile when the system must transition from 5-inch to 4-inch lines at a working pressure up to 75 psi at 70 F.

Check Gasket Material And Locking Arm

Verify that nitrile gaskets are compatible with the media being conveyed and that the 75 psi rating meets the maximum pressure in your circuit. Confirm the 6 11/16-inch overall length fits the available space and that the included locking arm satisfies your safety requirements.

Questions about this item

What size hose or pipe does the 5 in socket and 4 in plug fit?

The socket has a 5 in inside diameter and the plug has a 4 23/32 in outside diameter for matching cam-and-groove connections.

How do I install the coupler and adapter, and what step is often missed?

Align the cam arms on the socket with the groove on the plug, push together, then close both locking arms to secure the joint.

When should the nitrile gasket be replaced?

Replace the nitrile gasket if it shows cracks, hardening, or if leaks appear at the seal during pressure checks.
