QI-LOK tubing and tube fittings are precision-engineered to deliver secure, leak-tight performance in high-pressure and high-temperature instrumentation systems. Designed with a robust body, nut, and dual-ferrule system (front and back ferrules), they ensure strong tube gripping, reliable sealing, and excellent resistance to vibration and fatigue.
Our dual-ferrule design allows for easy installation without excessive torque while maintaining consistent performance throughout the system’s service life. These fittings are ideal for critical applications where safety, reliability, and long-term integrity are essential.
QI-LOK tube fittings are manufactured using high-quality raw materials under strict quality control processes. Available material options include:
Stainless Steel (SS304, SS316/316L)
Duplex & Super Duplex
Monel, Hastelloy, and other special alloys
This wide material range ensures compatibility with corrosive media, extreme temperatures, and demanding operating conditions.
QI-LOK tubing and tube fittings are available in a comprehensive range of:
Tube sizes and wall thicknesses
Straight, elbow, tee, and cross configurations
Male and female threaded connections
Custom configurations can also be supported based on project requirements.
Dual-ferrule engineering ensures secure tube gripping and consistent leak-tight sealing.
Designed to withstand high pressure and temperature in demanding industrial conditions.
Available in multiple alloys, sizes, and configurations for diverse applications.
Trusted for safe, long-term performance in critical and mission-essential systems.
