3 inch Female Coupler x FNPT 316 SS

This 3 inch female coupler connects hoses or pipes using a Cam and Groove Type D socket with an FNPT thread. The body is made from 316 stainless steel for corrosion resistance in plumbing and fluid transfer applications. It includes a locking arm and nitrile gasket for a secure seal.

Check thread size and pressure rating

Verify that the existing system uses a 3 in -8 thread size and NPT connection type before ordering. The maximum working pressure is rated at 125 psi at 70 F, so confirm this matches your operating conditions. Ensure the 3 5/8 in socket inside diameter suits your hose or pipe.

Thermals noise and power draw

As a passive mechanical fitting, this coupler generates no heat, noise, or power draw during normal use. Performance depends on proper installation and the integrity of the nitrile gasket. The 316 stainless steel body maintains structural stability across typical temperature ranges.

Questions about this item

Does the 3" Female Coupler x FNPT 316 SS Coupler come with a gasket or must one be purchased separately?

A nitrile gasket is included with the coupling so no separate gasket purchase is required.

When should I choose the 316 stainless steel version over other materials for this 3" Type D cam and groove fitting?

Choose 316 stainless steel when the application demands higher corrosion resistance than standard steel or brass can provide.

What does the 125 psi rating at 70 °F mean for daily operation of this 3" coupler?

The coupling is rated for a maximum working pressure of 125 psi when the media temperature is 70 °F; pressure capacity decreases at higher temperatures.
