Fairfax Pressure Temperature Test Plugs are an economical and efficient option for measuring pressure or temperature in closed systems. They eliminate the need for expensive inline gauges and testing equipment and make system shutdown unnecessary for pressure and temperature checks.

Our exclusive double-sealing core insures long and trouble-free service and is consistently rated at 1000 PSI depending on application. We offer core materials for a wide range of applications including: hot water, chilled water, air, lubricating oil, gasoline, natural gas, refrigerants and aliphatic hydrocarbons.

We cater to small and large companies alike, giving each the personal service that comes with a hands-on approach from the owners and staff.
