Female NPT To Quick-Test Male High Pressure

These NPT female adaptors are for connecting your NPT male thread to our Ralston quick test system. By having the Ralston system, you can then use a Ralston hose to connect to your calibrator. Alternatively, you can use a union to adapt to other thread sizes or connectors.

Please click on the options tab above to see the sizes and threads available for these male adaptors.

Please note the XT fittings aren’t compatible with the QT 350 bar & hoses fittings, they have a different Quick-test thread so won’t screw together.
