Compression Fittings

To connect a compression fitting, insert the tube into the fitting body, then tighten the nut so the ferrule compresses around the tube, forming a tight seal. Proper torque is critical to avoid leaks or damage. Manufacturers like Hy-Lok provide specific tightening guidelines to ensure consistent, leak-free performance across applications.

Hy-Lok compression fittings are manufactured from globally sourced, high-performance alloys selected for durability and corrosion resistance. These materials are engineered to withstand high-pressure and high-temperature conditions found in oil and gas, chemical processing, and other demanding industrial environments.

Yes, Hy-Lok tube and pipe compression fittings are specifically engineered for high-pressure and high-temperature process environments, including upstream, midstream, and downstream oil and gas operations. Their robust design and premium alloy construction make them well-suited for demanding instrumentation and fluid control applications.

Tube fittings connect tubing used primarily in instrumentation and precision fluid control systems, while pipe fittings connect larger pipes used in broader fluid transport and hydraulic systems. Hy-Lok offers both types, engineered for leak-tight performance across a range of industrial and oil and gas applications.

In many cases, quality compression fittings like Hy-Lok's can be reassembled after disconnection, provided the ferrule and tube remain undamaged. However, for critical high-pressure or safety applications, it's recommended to inspect components carefully or replace ferrules to maintain a reliable, leak-tight seal.

Most compression fittings can be installed using standard wrenches, though proper torque specifications should be followed to prevent under- or over-tightening. Hy-Lok provides installation guidance to ensure fittings achieve a secure, leak-tight seal without specialized tooling for most standard applications.
