Construction Details
The Type D fitting features a durable iron body with a female cam & groove coupler on one end and female NPT threads on the opposite end.
The female camlock coupler accepts a compatible male cam & groove adapter. Closing the cam arms draws the mating adapter against the gasket inside the coupler and secures the quick-connect connection.
The female NPT end threads onto compatible male NPT pipe, nipples, valves, pumps, tank connections, manifolds, or other male-threaded equipment.
Connection Configuration
Female Camlock Coupler
The female cam & groove end accepts a compatible male camlock adapter of the appropriate nominal size. Closing both cam arms secures the mating adapter inside the coupler.
Female NPT
The opposite end provides female National Pipe Taper threads for installation onto compatible male NPT pipe, nipples, valves, pumps, tanks, manifolds, and other threaded components.
How a Type D Camlock Works
Install the female NPT end onto the appropriate male threaded connection using a suitable pipe-thread sealant when required for the application.
To make the camlock connection, open both cam arms and insert a compatible male cam & groove adapter into the Type D female coupler. Close both cam arms using normal hand pressure to secure the connection.
For disconnection, safely depressurize and drain the system as appropriate, raise both cam arms, and remove the male adapter from the Type D coupler.

What is a Type D iron cam & groove fitting?
A Type D fitting has a female cam & groove coupler on one end and a female NPT threaded connection on the other.
Does a Type D coupler have cam arms?
Yes. The female camlock coupler uses cam arms to secure a compatible male cam & groove adapter.
What connects to the female camlock end?
The female coupler accepts a compatible male cam & groove adapter of the appropriate nominal size.
What connects to the female NPT end?
The female NPT connection threads onto compatible male NPT pipe, nipples, valves, pumps, tank connections, manifolds, or other male-threaded components.
What material is this Type D fitting made from?
This Type D cam & groove coupler features iron construction.
What is the difference between Type D and Type A?
Type D is female camlock x female NPT, while Type A is male camlock x female NPT.
What commonly mates with a Type D coupler?
A Type D coupler is commonly paired with a compatible Type A male adapter of the same nominal camlock size. Compatible Type E and Type F male adapters and Type DP dust plugs can also mate with the female camlock connection when properly sized.
Can cam & groove fittings be used for compressed air or steam?
No. Cam & groove couplings should not be used for compressed air or steam service. Always verify fitting material, gasket, pressure, temperature, and transferred-media compatibility before installation.
Important Ordering & Installation Notes
- Confirm both connection sizes before ordering.
- Type D configuration is female camlock x female NPT.
- Use with a compatible male cam & groove adapter.
- Use suitable pipe-thread sealant on the NPT connection where required.
- Verify iron, gasket, pressure, temperature, and application compatibility before use.
