It is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. This union connects two tubes in a straight run. It has a compression connection on both ends for connecting unthreaded tube. Tightening the nut against the sleeve creates a compression seal against leaks, and loosening the nut allows disassembly of the joined parts. This three-piece construction fitting – nut, sleeve, and body – can be used with copper, brass, aluminum, or plastic tubing and has an operating temperature range of -65 to +250 degrees F. This union compression tube fitting is suitable for use with fuel and gas systems, plumbing, refrigeration, and vacuum applications. Tube fittings are components used for connecting, branching, terminating, and changing the direction of tubing in pneumatic and hydraulic systems. They are made of brass, stainless steel, PBT (polybutylene terephthalate), and other materials that resist corrosion and wear. Tube fittings have various types of connections, including threaded, welded, barbed, and push-to-connect (also called one-touch). Push-to-connect connections do not require tools or sealants. Tube fittings are used in various applications, including machine tools, airplane and truck controls, and automated production lines, among others. ## Features - About this item - Reducing union for connecting and disconnecting two tubes more easily than with a coupling Compression tube connections on both ends Brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability Operating temperature range of -65 to +250 degrees F Three piece construction - nut, sleeve and body ## Images ![Vis Brass Compression Tube Fitting, Reducing Union, 3/8" Tube OD x 5/16" Tube OD (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/51ZAzlXxH4L.jpg) ![Vis Brass Compression Tube Fitting, Reducing Union, 3/8" Tube OD x 5/16" Tube OD (Pack of 1) - Image 2](https://m.media-amazon.com/images/I/5166TDtdj-L.jpg) ![Vis Brass Compression Tube Fitting, Reducing Union, 3/8" Tube OD x 5/16" Tube OD (Pack of 1) - Image 3](https://m.media-amazon.com/images/I/519UD0qBAdL.jpg) ![Vis Brass Compression Tube Fitting, Reducing Union, 3/8" Tube OD x 5/16" Tube OD (Pack of 1) - Image 4](https://m.media-amazon.com/images/I/5101tDC2CoL.jpg) ## Available Options This product comes in different **Size, Item Package Quantity** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hard to find fitting. *by A***P on Reviewed in the United States on October 1, 2021* This fitting was just what I needed, to connect my new dish washer to the 30 year old water line. None of the big box or local hardware stores carried this part. ### ⭐ Wrong Dimensions *by A***K on Reviewed in the United States on September 6, 2019* I either received the wrong part, or the dimensions described in the title are incorrect. What I received was a 1/4" to 3/8" Union - which I didn't need. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/129792380-vis-brass-compression-tube-fitting-reducing-union-3-8-tube](https://www.desertcart.tn/products/129792380-vis-brass-compression-tube-fitting-reducing-union-3-8-tube) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
