About Our Semiconductor Components

Given the importance of semiconductor manufacturing processes, sourcing quality components and peripherals is of the utmost importance, and Hy-Lok can help. We supply components that meet industry quality standards at affordable prices. Producers of semiconductors rely on our tools, valves and fittings to create world-class products.

Quality Design:

Our valves and fittings are designed to meet strict thresholds, so that our customers can comply with ISO and other industry-recognized quality standards. Our high-purity values are 100 percent clean and free of contaminants. Our quality control standards, which includes stress testing our products, are consistent with industry best practices. We also offer warranties on our products, adding to the value clients realize from our semiconductor components.



We offer valves that give clients connectivity options depending on the application. Each of our valves carries the same quality guarantee. The design specifications and tolerances vary by model.

Diaphragm Valves – Made from 316L VIM/VAR, Diaphragm Valves are resistant to corrosion and abrasive materials used in semiconductor production. This resistance extends the useful life of the valves, making them a viable option for precise manufacturing processes.

Bellow Valves – This product features an all-metal seal, temperature rating up to 200°F (93 C) and a maximum working pressure of up to 500 psi (34.4 bar). The precise construction of the valve, combined with its ease of use and functionality, make it ideal for applications in multiple production processes.


We offer a variety of fittings suited for instrumentation and other delicate manufacturing processes. This includes the models below, which are popular in semiconductor production.

ZCR Face Seal Fittings – Our metal gasket face seal fittings are highly reliable, meeting or exceeding semiconductor industry quality standards. These fitting are ideal for tube connections up to 1″ O.D. They have also been tested to exceed a leak rate of 10-9 torr.

Weld Fittings – This product ranges from 1/8″ T to 1″ T for tube configurations and 1/8″ NPT to 1″ NPT for tube to male and female pipe configurations. With a wide variety of applications, this fitting can reliability withstand the rigors of production

Common Applications:

  • Agriculture equipment
  • Heavy industry
  • Instrumentation
  • Pneumatic
  • Hydraulic
  • Compressor manufacturing
  • Research facilities, and more.
