REDUCING PORT CONNECTOR

REDUCING PORT CONNECTOR

The Reducing Port Connector is engineered to connect tubing to a port while simultaneously transitioning between different sizes, providing a streamlined solution for systems requiring space-saving and size-reduction functionality. One end is designed for METALOK-compatible tube fittings, while the other features a male or female threaded connection—such as NPT, BSPT, or BSPP—in a smaller or larger size. This dual-function connector eliminates the need for multiple fittings or adaptors, offering a compact and efficient alternative in process, instrumentation, and hydraulic systems. It is available in sizes ranging from 1/8” to 2” (or 3mm to 50mm), and is manufactured from corrosion-resistant materials such as Stainless Steel (SS), Brass, Duplex, Monel, and Hastelloy.

  • Tube fitting to threaded port connection with size reduction.
  • Compatible with METALOK and standard tube fittings.
  • Available in a variety of thread types: NPT, BSPT, BSPP.
  • Manufactured from high-grade corrosion-resistant materials.
  • Compact design eliminates the need for separate reducers or adapters.
  • Enables direct connection between mismatched port and tube sizes.
  • Reduces complexity, weight, and space usage in system layouts.
  • Offers leak-tight sealing for high-pressure and corrosive applications.
  • Simplifies installation and reduces inventory of multiple components.
  • Ideal for compact instrumentation, control panels, and process piping.
