Ralston Male NPT Quick-test™ Fittings make periodic calibration of pressure instruments as easy as can be.
- Do you need to periodically calibrate pressure instruments in the field in harsh environments?
- Do you have to check pressures of systems that are under pressure?
- Do you need the reliability of a dual pressure seal system?
If the answer is yes to any of these questions then you should use Ralston Male Quick-test™ fittings. Connect to pressure transmitters, EFMs, Flow Computers and other NPT devices under test using thread sealant for a permanent connection. Install these fittings only once with thread sealant – after that you can connect to them using just your fingers. This makes calibration easy and quick by connecting and disconnecting a hose without a wrench or thread sealant. The built-in cap protects the fitting from mud, dirt and contamination. An optional check-valve means you can connect to to systems under pressure up to 3000 psi (210 bar). If you get a fitting with a cap and a check valve there will be two independent pressure seals when the fitting is on-line in the field. These fittings are available in brass and stainless steel. If the process has chemical compatibility issues such as sour gas then stainless steel is a better option.
Ralston Male NPT Quick-test™ fittings are available in a wide range of NPT sizes and best of all they are from Ralston Instruments so you can count on their reliability and long life in the field.
