3 inch stainless steel male adapter spool coupling

Dixon Valve & Coupling Co.

Dixon Valve & Coupling Co. 300-AA-SS 3 in Male Adapter Spool Coupling 316 Stainless Steel 125 psi

SKU CH-3HRY-NP7Z4

A 3-inch 316 stainless steel male adapter spool coupling rated for 125 psi at 70 F

  • 316 stainless steel body resists corrosion in demanding fluid systems
  • Male adapter by male adapter design joins two female cam couplings directly
  • 125 psi rating at 70 °F suits moderate-pressure transfer applications
  • 3 inch coupling size matches standard large-bore hose and pipe assemblies
  • Locking arm included secures connection against vibration and pressure surges

3-inch Male Adapter Spool

This 3-inch male adapter spool coupling joins two female cam-and-groove fittings in fluid-transfer lines. The 316 stainless steel body resists corrosion in chemical, food-grade and marine applications. It is built for operators who need a straight-through connection without reducing flow diameter.

125 psi at 70 °F limit

Maximum working pressure is rated at 125 psi measured at 70 °F, so system pressure must stay below that value at ambient temperature. Higher temperatures will lower the safe pressure ceiling, and the coupling is not rated for vacuum or steam service. California Proposition 65 warnings apply to substances present in the component materials.

Locking-arm security

An integrated locking arm secures the cam levers against accidental release during vibration or pressure surges. The overall length of 4 3/8 inches and plug outside diameter of 3 19/32 inches fit standard 3-inch cam-and-groove profiles. The plug length of 2 inches provides full engagement without bottoming out in shallow ports.

Questions about this item

Which coupling size and material suit a 3 in stainless steel line?

The 300-AA-SS is a 3 in cam-and-groove spool adapter made from 316 stainless steel, giving the corrosion resistance needed for aggressive fluids.

What does the 125 psi rating mean once the adapter is installed?

At 70 °F the spool adapter is rated for a maximum working pressure of 125 psi; pressure capacity drops as temperature rises above that point.

How does the male-adapter-by-male-adapter connection affect the joint?

Both ends are male cam-and-groove plugs, so each side locks into a female coupler with the built-in locking arms for a secure, tool-free connection.
