Connectors
NOSHOK offers Stabilized & Non-Stabilized Connectors, as well as Stabilized Connectors With Integral Block Valve designed to reinforce the entire installation by shifting radial-stress load away from the NPT connections.
Dielectric Kits DK Series
Dielectric Kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection. Dielectric Kits provide a non-conductive barrier between the process piping and the instrument and isolate components from the effects of electrical current. By eliminating metal-to-metal contact, current is halted to prevent corrosion and aid in the cathodic protection of the system.
  • One Piece Dielectric Gasket, Pair, Steel, Acetal (DK1)
  • One Piece Dielectric Gasket, Pair with Stainless Steel Bolts, Stainless Steel, Acetal (DK1-SS)
  • PTFE Gasket with Dielectric Shim, Pair, Steel, PTFE, PVC (DK2)
