These NPT Male adaptors come in both Stainless Steel and Brass materials and are for connecting your NPT  female thread to our Ralston quick test system. By having the Ralston system you can then use a Ralston hose to connect to your calibrator. Or using a Union you can adapt to other thread sizes or connectors.

Great fittings for screwing into  a fitting or manifold and leaving it there and even cap it off with a cap and chain so you can seal it leak tight - ready for your next calibration or test.

Please click on the options tab above to see the sizes and threads available for these male adaptors. The 3000 PSI ones have the check valve installed the 5000 PSI ones do not.
