Chemical Processing


Hy-Lok UK provides a comprehensive selection of chemical processing fittings and fluid controls for the chemical processing and petrochemical processing industries.

We manufacture and supply tube fittings, pipe fittings, ball valves, inline filters, check and relief valves, instrument manifolds, calibration fittings, and sampling cylinders made from the highest grade 316 stainless steel, brass, carbon steel, and special alloy materials.

Hy-Lok UK is also proud to be involved in the chemical industry, a diverse and dynamic space that offers products ranging from cosmetics to plastics, fuel products to health care products, food additives, and much more.

We offer solutions for a range of chemical processing applications. These include:

  • Heat transfer
  • Evaporative cooling
  • Evaporating and drying
  • Distillation
  • Mass separation
  • Mechanical separation
  • Mixing

Some of our chemical processing solutions are used in chemical and petrochemical applications in research labs, pilot plants, and production processes. In addition to our tube and pipe fittings, ball valves, needle valves, and check and relief valves, we also provide instrument manifolds, calibration fittings, and sampling cylinders.

Hy-Lok UK can also provide valve and fitting solutions made of any material necessary for the application. These include stainless steel (316), brass, carbon steel, and a range of special alloys.

We carry ISO 9001, ISO 14001, OSHAS 180001, ASME, API, API FireSafe, and PVD certifications for quality, safety, and environmental protection to ensure our customers are provided with the highest quality and most reliable fittings, valves and components available. We offer complete material traceability, including record of any heat treating processes performed on the material, and 100% of all valves are leak-tested at the factory. Our size and efficiency allow us to provide these premium products to our customers at the most cost competitive prices anywhere.
