Dielectric fitting

Dielectric Fittings and Adapters

Installed on impulse lines ahead of monitoring stations in natural gas pipelines, dielectric fittings interrupt cathodic current while permitting full flow. 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 climatic conditions.

Gaugeable Swagelok tube fitting or tapered pipe thread end connections (NPT/BSP) provide direct connection to tubing or piping systems.
