Product Overview

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.

Petes Plugs Gauge Adapter

The Pete’s Plug adapter permits the technician to use gauges for pressure readings with an installed Pete’s Plug. The adapters are probes (needles with holes in the end) with a threaded fitting. The technician does not leave the adapter in the line. It is reusable. The Pete’s Plugs Gauge Adapters are available in different configurations (probe diameters and probe lengths), the most popular Pete’s Plug Adaptor being:

Model 500 Gauge Adapter

(1/4” NPT female adapter with a 1/8” diameter probe)—Model 500 has a thicker probe and is more robust; however, it will not work with Pete’s Plug model 12500 (1/8” test plug).

Model 510 Gauge Adapter

(1/4” NPT female adapter with a 1/16” diameter probe)—Model 510 works on any size of Pete’s Plug. While this adapter is not as robust as the Model 500, many utilities like the ease the thinner probe offers when inserting into the Pete’s Plug.

Model 510-S Gauge Adapter

is a shorter version of the Model 510 that works well when depth clearance is a concern. They are commonly used with Fisher or Belgas 627 regulators when a Pete’s Plug is in the valve body.

Model 500XL Gauge Adapter

(1/4” NPT female adapter with 1/8” diameter probe)—The 500XL are “extra-long” and pair with extra-long Pete’s Plugs, and for use when clearance issues occur.
