Value Brand 4 in Aluminum Cam and Groove Coupling Type D

SKU CH-MXPD-THC84

Aluminum Type D cam-and-groove coupling with 4-inch NPT thread and 100 psi working pressure

  • Aluminium body resists corrosion for longer service life
  • Type D female NPT thread connects 4 in hose directly
  • 100 psi rating at 70 F handles standard fluid pressure
  • Nitrile gasket seals reliably across common temperature ranges
  • Locking arm included so assembly stays secure under vibration

4-inch Aluminum Cam and Groove Coupling

This Type D coupling provides a 4-inch female NPT connection for industrial fluid transfer. The aluminum body and nitrile gasket suit water, oil and compatible chemical lines. It is built for plant maintenance crews and OEM assemblers who need a quick-disconnect fitting rated to 100 psi at 70 °F. Buyers who require a male adapter or a different coupling type will need a separate component.

Pressure and temperature limits

The fitting carries a maximum working pressure of 100 psi measured at 70 °F. Pressure capacity falls as temperature rises, so systems operating above this temperature must be derated accordingly. The nitrile gasket defines the chemical and thermal envelope; fluids outside its compatibility range will degrade the seal. Installations that exceed the stated pressure or temperature envelope are not supported by this design.

Build quality and daily use

The aluminum socket measures 4 47/64 inches inside diameter and 3 11/16 inches overall length with 4-inch 8-thread NPT threads. An integrated locking arm secures the cam levers against accidental release during vibration or pressure cycling. The lightweight alloy eases handling on large-bore hose assemblies while resisting corrosion in typical plant environments. Thread sealant is required on the NPT connection to prevent leakage.

Questions about this item

Should I choose the 4 inch Type D coupling or a different size for my hose?

This coupling is a 4 inch Type D with a female NPT thread and a hose fitting size of 4 inches, so match it to a 4 inch male cam and groove adapter and a 4 inch hose.

What does the 100 psi rating at 70 F mean when the coupling is installed?

The coupling is rated for a maximum working pressure of 100 psi at 70 F; pressure capacity may decrease at higher temperatures.

How does the NPT thread affect the seal and what pressure can it handle?

The 4 inch -8 NPT thread seals on the taper with thread sealant and the coupling handles up to 100 psi at 70 F.
