Pete’s Plugs

The Pete’s Plug (or Petes Plug) facilitates easy temperature or pressure readings from your gas lines, eliminating the need to leave gauges or temperature indicators on the line.

Pete’s Plugs

Pete’s Plugs II® allows you to quickly take temperature or pressure readings from your gas line and eliminate the need for leaving expensive gauges or temperature indicators on the line.

If you have Petes Plugs with yellow straps, the internal valves are Nordel (EPDM), indicating that the plug is for hydronic use. Since Nordel deteriorates in natural gas over time, make sure your caps are blue.

We are an authorized distributor through IMAC Systems, the only Pete’s Plug distributor in the USA for natural gas applications.

Features & Benefits

Petes Plug | Temperature or Pressure Readings

For natural gas use, make sure the plastic fastener is blue.

This enhanced version of Petes Plug® is still the only pressure and temperature test plug with two self-closing valves, but the valves are improved with interaction, which speeds valve closure. Pete's Plug II® is available in various pipe thread sizes, lengths, and materials to satisfy each application. The XL series Pete's Plug II® will allow you to insulate the test point and not completely cover Petes Plug II®. XL Petes Plug II® eliminates extra fittings for insulated applications.

Do not be fooled by imitation Petes Plugs with single cores, look for the embossing right on the plug body that says "Petes Plug II."

Pete's Plug is a registered trademark, and the valve design is fully patented.
