Jaco Kynar®, Nylon & Polypropylene Tube Reducing Union Fittings

Jaco reducing union connectors are precision compression fittings designed to securely connect two tubes of different diameters. These fittings use a compression nut and ferrule system to create a tight, leak-resistant seal without the need for threading. Available in multiple materials to suit a wide range of temperatures, chemicals, and applications, these fittings are ideal for fluid handling, pneumatic, and instrumentation systems. Their durable construction and simple installation make them a reliable choice for both industrial and laboratory use.
