Pressure & Vacuum Feedthroughs

Pressure and vacuum feedthroughs play a critical role in safely transferring signals, fluids, or power through sealed system boundaries without compromising performance. At HK Calibrations Australia, we supply high-quality pressure feedthroughs and vacuum feedthroughs engineered for precision, durability, and leak-free operation.

Our range is designed for use in laboratory equipment, vacuum chambers, pressure vessels, industrial processing systems, and testing environments where maintaining system integrity is essential. Each feedthrough is manufactured to withstand demanding pressure and vacuum conditions while ensuring consistent, reliable transmission.

Suitable for research, industrial, and calibration applications, our feedthrough solutions support accurate measurements, controlled environments, and long-term operational stability. With robust materials and proven sealing performance, they help minimise system failures and downtime.

Frequently Asked Questions

Feedthroughs are specialized components designed to transfer electrical signals, liquids, or gases from outside a chamber to the inside while maintaining a hermetic seal. They are essential for protecting the integrity of a vacuum or high-pressure environment during complex industrial or laboratory experiments.

The collection includes high-performance solutions such as the Spectite range, which features multi-hole and individual wire feedthroughs. These are engineered to handle various probe diameters and wire counts, allowing for customized configurations based on the specific sensors or leads being used.

These components typically utilize stainless steel bodies combined with specialized internal sealants like PTFE, Viton, or Neoprene. This combination provides excellent chemical resistance and mechanical strength, ensuring the seal remains intact under extreme pressure or thermal stress.

Selection depends on the number of wires or probes passing through and the diameter of the entry port on your chamber or pipe. You must match the feedthrough’s thread size and internal sealing capacity to your specific equipment to prevent leaks and ensure a secure fit.

Yes, many models are specifically designed for high-temperature applications, such as furnace monitoring or chemical processing. By selecting a feedthrough with heat-resistant sealants, you can safely pass thermocouples and power leads into hot zones without compromising the vacuum seal.

Even a microscopic leak can contaminate a vacuum environment or cause dangerous pressure drops in industrial systems, leading to failed experiments or equipment damage. Using precision-engineered feedthroughs from HK Calibrations ensures a reliable, airtight barrier that supports accurate and safe operational results.
