PETE'S TEST PLUGS

For pressure and temperature measurements

General Information

Pete's Test Plugs allow pressure or temperature readings to he taken quickly and are designed to eliminate the need for gauge cocks and thermometer wells. These test plugs have wide application; popular examples of their use include hot and chilled water systems, heat exchangers and pumps.

This enhanced version of Pete's Plug is the only pressure and temperature test plug with two selfclosing valves. The values are improved with interaction, which speeds valve closure and so improves safety.

Operation

The Pete's Test Plug is permanently installed in the line at recommended test points. The cap protects the valve and provides an additional seal. After the cap has been removed either a test thermometer or pressure gauge adaptor can be inserted through the two self-closing valves.

Tests should be made as quickly as possible since the valve reseal time is dependent upon time of insertion.
