SKU CH-N6JR-SS2JP

Aluminium cam-and-groove flange adapter connects a 3-inch flange at 125 psi working pressure

  • Flange connection simplifies pipeline assembly
  • Aluminium body resists corrosion in fluid systems
  • 125 psi rating at 70 °F suits moderate-pressure lines
  • 3-inch coupling size matches standard pipe dimensions
  • Locking arm included for secure cam-and-groove engagement

Flange Adapter 3 in 125 psi

The Dixon Valve & Coupling Co. 300-AL-AL is an aluminum cam and groove adapter with a flange connection. It suits fluid-handling systems that require a 3 inch coupling size and a maximum working pressure of 125 psi at 70 F.

Installers needing 3 in aluminum flange plug

This adapter fits setups using Type AL cam and groove couplings with a flange end. It is not for systems that demand a different coupling size, a higher pressure rating, or a body material other than aluminum.

Verify coupling size and pressure rating

Confirm the existing line uses a 3 inch Type AL cam and groove interface and that operating pressure stays within 125 psi at 70 F. Check that the flange bolt pattern matches the mating flange and that aluminum is compatible with the conveyed media.

Questions about this item

What flange standard and bolt pattern must the mating flange match for the 3-inch Dixon adapter?

The adapter uses a 3-inch flange connection rated at 125 psi at 70 °F; the mating flange must share the same nominal size and pressure class to seal correctly.

Will the aluminum body and locking arm resist galvanic corrosion when paired with steel or iron pipework?

Aluminum in direct contact with dissimilar metals can corrode; use insulating gaskets or dielectric flanges and keep the joint dry to limit galvanic attack on the adapter body and locking arm.

How can I confirm the adapter is seated and locked after installation?

Verify the cam arms snap fully over the locking arm, the plug outside diameter of 3 39/64 inches sits flush against the flange face, and no leakage appears when the system is pressurised to 125 psi at 70 °F.
