Pete's Plug® Test Plugs

In general, the Pete‘s Plug® is a time and money-saving device which is well-suited for most plant and pipeline systems and is designed to eliminate gauge cocks and thermometer wells. Hot and chilled water systems, heat exchangers, pumps, differential readings, air, gas lines and numerous other applications are only a few of the areas where the Pete‘s Plug® are presently being used.

Pete‘s Plug® will allow you to take pressure and temperature readings quickly and eliminate the need for leaving costly gauges or temperature indicators on the line. Depending on the application, the Pete‘s Plug® can be operated to a maximum of 1,000 PSI and 200° or 275°F (93°C or 135°C) for neoprene or nordel respectively. A maximum working pressure of 1,500 PSI can be obtained within the temperature ranges of 140° to -20°F (60°C to -29°C) within reasonable time frame to return the cap for a securely closed system.

How to Operate

The Pete‘s 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 a gauge can be inserted through the two self-closing valves in the Pete‘s Plug®. Readings are made and adjustments or tests can be accomplished when the probes are withdrawn and the two valves close. The protective cap is then reinstalled. Tests should be made as quickly as possible since the valve reseal time is dependent upon time of insertion, time and pressure. Slower reseal time can be expected at a lower temperature and lower pressures.

• Neoprene is a chloroprene-based synthetic rubber and it is resistant to deterioration from waxes, fats, oils, greases, petroleum products and most refrigerants.
• Nordel is an ethylene-propylene-based synthetic rubber and gives excellent service in hot and cold water and in some applications of low steam. Nordel is resistant to detergents, phosphate esters, ketone, alcohols and glycols.
