Swagelok SS-600-6-4 stainless steel tube fitting is a reducing union designed to connect 3/8 in. and 1/4 in. fractional tubing. Constructed from 316 stainless steel, this straight fitting provides a reliable, leak-tight connection in a linear path, making it ideal for maintaining flow efficiency in compact and critical fluid systems. The fitting undergoes Swagelok Standard Cleaning and Packaging (SC-10) to ensure high-quality performance in industrial applications.

Straight Reducer Design

Straight reducer fittings are used to connect tubing of different sizes. This configuration is particularly useful for system transitions where a change in tube diameter is required without changing the direction of flow. The SS-600-6-4 model ensures robust tube grip and vibration resistance, which are hallmarks of the Swagelok tube fitting design.
