3-Inch 316 Stainless Cam Adapter

This 3-inch Type A cam and groove adapter connects a male cam end to a female NPT thread. The body is 316 stainless steel for corrosion resistance in water, chemical and food-grade lines. It suits plant maintenance crews and OEM fabricators who need a quick-disconnect fitting rated for 125 psi at 70 F. Buyers needing a smaller bore or a different alloy should look elsewhere.

Pressure Behaviour Over Time

The 125 psi rating applies at 70 F; pressure capacity falls as temperature rises, so sustained high-temperature service requires derating. The 316 stainless construction resists creep and stress corrosion better than carbon steel during long runs. No locking arm is included, so the joint relies on cam tension alone under vibration. Systems that cycle pressure continuously should verify the cam groove wear interval.

Installation Checks

Confirm the mating female thread is 3-inch NPT and that the 3 19/32-inch plug outside diameter clears adjacent piping. The overall length is 2 3/4 inches, so measure the available envelope before ordering. California Proposition 65 warnings apply for cancer and reproductive harm; ensure compliance with local handling rules. No gasket or locking arm ships with the adapter.

Questions about this item

How much heat does the 316 stainless steel body generate when fluid runs through it at 125 psi all day?

The adapter itself produces no heat; temperature rise comes only from the fluid and ambient conditions at the 70 F reference point.

What pipe thread must my existing plumbing have to connect this 3 in -8 FNPT coupling?

You need a matching 3 in -8 male NPT thread on the pipe or fitting you are joining to this adapter.

Will the 3 19/32 in plug diameter fit inside the 3 in cam arms on my older aluminium cam-lock fittings?

Yes, the 3 19/32 in outside diameter matches the standard 3 in cam-and-groove profile used on older aluminium bodies.
