NEWPORT® Self-Sealing Plugs will allow you to take pressure and temperature readings quickly and eliminate the need for leaving costly gauges or temperature indicators on the line. The NEWPORT® plug is permanently installed in the line at recommended test points. The cap protects the valve and provides an additional positive seal. After the cap has been removed, either a test thermometer or a gauge adaptor with the proper pressure gauge attached can be inserted through the two self-closing valves in the plug. Readings are taken, adjustments or tests can be made, and when the probes are withdrawn, the two valves close. The protective cap is then reinstalled.
