Description & Features

Designed for connecting two different tube sizes within a single inline fitting, this stainless steel reducing union steps down from 1/2 inch to 3/8 inch tube outside diameter. The SUR-8-6-S6 is suited for hydraulic and industrial fluid systems where a direct, leak-resistant transition between differing tube sizes is required without additional adapters or fittings.

Stainless steel construction provides corrosion resistance appropriate for demanding fluid handling environments. The male configuration supports straightforward inline installation between compatible tube ends.

Question by: Kirk K on Nov 27, 2025, 1:50 PM
What size tubing does this fitting work with? I need to connect a half-inch line to a three-eighths inch line.

This reducing union is designed to connect a 1/2 inch outside diameter tube to a 3/8 inch outside diameter tube. It's made for situations where you need to step down the tube size in your hydraulic system.
