Pressure & Temperature Plug Accessories

Take pressure or temperature readings quickly

Pressure or Temperature Tests

This system allows you to quickly take pressure and temperature readings with the line pressurized. It reduces the need for costly permanent installation of gauges and recorders.

Suggested Project Specifications

Pressure and temperature test stations: Install a Pressure & Temperature Plug into a 1/4" fitting to receive either a 1/8" OD temperature or pressure probe. Fitting shall be solid brass with two valve at 500 psi, fitted with a color coded cap strap with gasket, and shall shall supply the owner with pressure gauge adapters with 1/8" OD probe and five inch stem pocket testing thermometers;

Pressure Gauge

The pressure gauge adapter has a probe constructed of 304 stainless steel. The probe is 1/8" in diameter and extends 2" (1 1/2" exposed probe) on the 312-500 adapter and 3 1/2" (3" exposed probe) on the 312-500-XL adapter. The 1/8" diameter probe is less likely to become clogged with foreign material and resists bending. Also, the 1/8" diameter probe operates in either the 1/4", 3/8", or 1/2" Plug. Please note the 312-500-XL gauge adapter will operate in any of the Plugs.

Temperature Gauge

The test thermometer is constructed of stainless steel, has a 1 3/4" dial and has a bi-metallic sensing element. Accuracy within 1/2% over the entire scale can be expected. Pointer adjustment or recalibrations can be made by turning the hex nut on the back of the dial case while firmly holding the dial case. The stem should be immersed in a known, controlled temperature bath. Stem lengths are 5" and diameters of 0.156" or 4mm are maximum diameters that can be inserted onto the Plugs. Digital thermometers have the same specifications, but can not be recalibrated in the field.
