At Perfect Engineers, we design and manufacture high-performance Reducing Unions under our premier brand PE-LOCK. These precision-engineered fittings are specifically built to connect two tubes of different outer diameters, ensuring a leak-proof, vibration-resistant, and space-efficient transition within your fluid or gas system.
Whether you’re working in instrumentation, hydraulics, chemical processing, or aerospace, PE-LOCK Reducing Unions are the ideal choice for smooth flow continuity and seamless system integration.
A Reducing Union is a two-ended compression tube fitting that allows you to connect two tubes of different sizes (OD to OD) in a straight-line configuration. It functions just like a straight union but with unequal tube sizes, eliminating the need for adapters or reducers that add bulk or complexity.
PE-LOCK Reducing Unions are built for easy installation, reusability, and tight sealing even under demanding pressure and temperature conditions.
