Product Selection and Specifications
Hy-Lok Canada supplies a full line of instrumentation tube fittings, valves, and fluid control components. Our catalogue includes compression fittings, high-pressure valves, ball and needle valves, quick-connect couplings, manifolds, and tubing. We serve industries from oil and gas to hydrogen, petrochemical, power generation, and laboratory systems — offering reliable, leak-tight performance under demanding conditions.
Our fittings are available in 316 stainless steel, carbon steel, brass, and various special alloys for corrosive or high-purity environments. Pressure ratings depend on the material, wall thickness, and fitting size — many of our compression fittings are engineered for high-pressure service. Refer to the individual product data sheets for specific pressure and temperature ranges.
Yes. Hy-Lok’s instrumentation fittings are fully interchangeable with most leading global brands, including Swagelok® and Parker®, when installed correctly. This compatibility means you can confidently integrate Hy-Lok components into existing systems without extensive retrofitting.
Start by confirming the outer diameter (OD) and wall thickness of your tubing, as well as your connection type (e.g., NPT, BSP, SAE, metric). Next, consider pressure rating, media compatibility, and temperature. Our technical specialists can help you confirm sizing and compatibility to ensure a secure, leak-tight connection.
Absolutely. Hy-Lok Canada’s products meet a wide range of industry and regulatory standards, including CRN (Canadian Registration Number) for pressure fittings, ASME N-Stamp, DNV-GL, and ISO 9001:2015. Certifications and material traceability documentation are available upon request.
Yes — our team can help design or source custom-machined and special-alloy fittings for high-purity, hydrogen, or cryogenic applications. Whether you need a unique connection type, pressure rating, or material composition, Hy-Lok Canada offers flexible, made-to-order options.
Installation, Maintenance, and Best Practices
Clean, deburr, and inspect the tubing before assembly. Insert the tubing fully into the fitting body, then tighten the nut hand-tight before applying the recommended number of wrench turns or torque value. Avoid over-tightening, which can deform the ferrule and compromise the seal.
Ensure all components share the same material compatibility, wall thickness, and rating. Always use matched sets of Hy-Lok ferrules, nuts, and bodies — mixing brands can lead to leaks. After installation, perform pressure or helium leak testing before placing the system into service.
While fittings can sometimes be disassembled, reusing ferrules or nuts is not recommended in high-pressure or critical service. Ferrules are designed to deform during installation for a perfect seal, so they should be replaced if the fitting is removed or repositioned.
Inspect for signs of corrosion, vibration fatigue, thread wear, or leakage. Operate valves periodically to prevent seat sticking, and ensure lubricants (where applicable) are clean and compatible with your process media. In harsh or corrosive environments, increase inspection frequency.
- Mixing components from different manufacturers
- Over-tightening or under-tightening compression nuts
- Using damaged or improperly cut tubing
- Skipping leak testing
- Neglecting to use a backup wrench during installation
Following Hy-Lok’s recommended installation procedures ensures a safe, leak-tight system and prolongs component life.
Industry Applications and Media Compatibility
Hy-Lok Canada serves a wide range of sectors, including oil and gas, petrochemical, hydrogen and alternative fuels, mining, power generation, laboratories, and biopharmaceutical systems. Our fittings and valves are trusted anywhere reliable fluid control and leak prevention are critical.
Yes — we supply hydrogen-rated, CNG/LNG-compatible, and cryogenic fittings and valves designed for safety and long-term durability in extreme conditions. These products are tested for pressure integrity and gas permeability to meet industry standards.
Select materials based on media compatibility and process purity. For example, stainless steel 316 is ideal for most fluids, while special alloys like Monel®, Inconel®, or Hastelloy® may be required for aggressive chemicals. Our specialists can help you determine the best choice.
Yes. Many Hy-Lok components are designed for both high-temperature and cryogenic service. Always confirm the allowable temperature/pressure ratings for your specific fitting or valve in the technical datasheet.
Review your system’s pressure class, tubing dimensions, and connection types before replacing components. Because Hy-Lok fittings are interchangeable with major global brands, upgrades can typically be made without altering your system design — just confirm material and rating compatibility first.
