4-inch Aluminum Cam and Groove Adapter

This ZORO SELECT adapter connects a 4-inch male cam-and-groove plug to a 4-inch female NPT thread. It suits plumbing and fluid-transfer systems that use Type A couplings. The aluminum body resists corrosion in water, air and mild chemical lines.

100 psi maximum working pressure at 70 °F

The adapter is rated for 100 psi at 70 °F, which is the decisive figure for safe system design. Exceeding this pressure risks leakage or fitting failure. Always verify that your operating pressure and temperature stay within this limit before installation.

Sustained pressure holds at rated limit

Under continuous operation at or below 100 psi the aluminum body and NPT threads maintain a reliable seal without the creep seen in short-term burst tests. The 3-inch overall length and 4 11/16-inch plug diameter keep stress concentrations low during prolonged service. No locking arm is included, so the connection relies on the cam arms of the mating coupler.

Questions about this item

What does the 100 psi working pressure mean when the adapter is installed?

It is the maximum pressure the aluminum body can handle at 70 °F; system pressure must stay at or below this value to avoid leaks or damage.

How does the 4 in NPT thread limit what I can connect?

The female NPT thread only accepts a matching 4 in male NPT fitting; other thread forms or sizes will not seal.

What clearance is needed for the 4 11/16 in plug diameter?

The plug measures 4 11/16 in across, so the mounting hole or enclosure opening must be at least that wide to pass through.
