Swagelok® Dielectric Fittings

Swagelok dielectric fittings isolate and protect monitoring instruments from the effects of electrical current while still permitting full fluid flow, maintaining instrument accuracy and reducing instrument replacement costs.

View Dielectric Fittings

Swagelok dielectric fittings protect instruments by separating the two primary functions of electrical insulation and fluid containment. Molded thermoplastic insulation with excellent electrical, chemical, and ultraviolet resistance and low water absorption maintains dielectric strength and integrity over a wide range of operating and climate conditions.

Often installed on impulse lines ahead of monitoring stations in natural gas pipelines, dielectric fittings interrupt cathodic current while permitting full flow. Gaugeable Swagelok® tube fitting or tapered pipe thread end connections (NPT/BSP) provide direct connection to tubing or piping systems, reducing installation time.
