Value Brand

Value Brand 1" Male Adapter x MNPT 316 SS Coupling

SKU CH-WTWA-R5Q4Z

A 1-inch 316 stainless steel cam-and-groove male adapter with NPT threads rated to 250 psi at 70 °F

  • 316 stainless steel body resists corrosion
  • 1-inch NPT male thread fits standard piping
  • 250 psi working pressure at 70°F handles demanding systems
  • 2-25/32 inch overall length suits tight installations
  • Cam and groove Type F design enables quick connections

1" Male Adapter x MNPT 316 SS Coupling

This coupling connects a 1-inch hose fitting to a male NPT thread using 316 stainless steel. It suits fluid-handling systems that require corrosion-resistant connections in industrial or commercial plumbing applications.

Thermals Noise and Power Draw

As a passive mechanical fitting it generates no heat, produces no noise and draws no power during normal operation. Performance depends on the fluid temperature and pressure within the rated limits of the assembly.

Replaces Worn or Mismatched Threaded Couplings

The adapter upgrades leaking or incompatible threaded joints where a 1-inch Type F cam-and-groove plug meets a 1-inch NPT port. The jump is worth it when the existing fitting cannot handle 250 psi at 70 F or when 316 stainless steel is required for chemical compatibility.

Questions about this item

How do I install the 1 in -11-1/2 NPT threads and what step is often missed?

Wrap the 1 in -11-1/2 NPT threads with PTFE tape or pipe dope, then tighten to the recommended torque; the step often missed is applying enough thread sealant to prevent leaks at 250 psi.

What maintenance or replacement will the 316 stainless steel cam-and-groove adapter need later?

Inspect the 316 stainless steel body and locking arm for corrosion, wear, or deformation; replace the adapter if the plug outside diameter of 1 7/16 in shows pitting or the threads are damaged.

What limit appears first during sustained use at the 250 psi rating?

The maximum working pressure of 250 psi at 70 F is the primary limit; sustained operation at or above this pressure can cause seal failure or fitting deformation.
