At Perfect Engineers, we manufacture and supply precision-engineered Straight Unions under our trusted brand PE-LOCK. These tube-to-tube connectors offer a simple, strong, and leak-proof solution for joining two tubes of equal outer diameters in a straight line—ideal for high-pressure, high-temperature, and vibration-prone environments.
Our PE-LOCK Straight Unions are built with single or double ferrule technology, depending on your system requirements, and are widely used across instrumentation, oil & gas, chemical, power, and pharmaceutical sectors.
A Straight Union is a tube fitting used to join two sections of tubing with the same outer diameter. It provides a mechanical seal using either a single or double ferrule system, eliminating the need for welding, soldering, or adhesives.
PE-LOCK straight unions are fully reusable, easy to install, and interchangeable with global tube fitting brands.
