DT Series Dielectric Fittings

Features

• Metal components are machined from 316 stainless steel for use in rugged environments.
• Molded thermoplast ic 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 NAI- LOK® tube fitting or tapered pipe thread end connections (NPT/BSP) provide direct connection to tubing or piping system.

Dielectric Fittings

Dielectric fittings isolate monitoring instruments from the effects of electrical current. Installed on impulse lines ahead of monitoring stations in natural gas pipelines, the fittings interrupt cathodic current flow while permitting fu ll flu id flow.

The fitting design is unique in that it separates the two primary functions of electrical insulation and f luid containment. Thermoplastic insulators provide high dielectric strength over a wide range of operating and climatic condit ions. A fluorocarbon FKM quad seal contained in the fitting provides the primary fluid seal.
