Dielectric Fittings (CDF)

What Are Dielectric Fittings?
Dielectric fittings are designed to isolate dissimilar metals in fluid and gas systems, preventing galvanic corrosion and ensuring long‑term reliability. They provide both electrical insulation and leak‑tight sealing, making them essential for industries where safety and durability matter.

Hy-Lok dielectric fittings are engineered to deliver superior insulation and corrosion resistance in demanding industrial environments. Manufactured from 316 stainless steel with thermoplastic insulation, these fittings prevent galvanic corrosion between dissimilar metals, ensuring long‑term reliability in fluid and gas systems.

As the official Hy-Lok distributor in Malaysia, we provide certified dielectric fittings designed for data centres, semiconductor plants, chemical processing, and high‑purity applications. Each fitting is precision‑machined for leak‑tight performance, easy installation, and compliance with international standards.

Key Features

  • Enhanced safety through electrical isolation
  • Leak‑tight connections with NPT/BSP end options
  • Durability in high‑temperature and corrosive environments
