AHFMANG Brass Compression Tee Union, 5/16" OD, 2-Piece Set

Each connection is sized for 5/16" outside-diameter tubing. This two-piece set of brass compression tee unions brings three matching tube ends together at each junction. Use it with copper or plastic tubing for a branched line layout. The compression design uses a nut, sleeve and body to form the fitting assembly.

Quick sizing guide

All three ends of each tee are specified for 5/16" OD tubing, so the fitting is intended for a three-way junction with matching tube sizes. Check the tubing’s outside diameter when selecting a fitting, matching this measurement helps you choose the appropriate size for the connection. Because each tee has three connection points, it suits layouts where one line needs to meet or branch to two others. A straight union is a different approach for joining tube ends in a straight run, choose a tee when the layout calls for a junction.

Pros

Brass construction gives the fitting a solid metal body, and the product description notes corrosion protection for brake lines. The compression tee is designed for use with copper or plastic tubing, offering options for common tube materials. Its nut-and-sleeve assembly is described as easy to disassemble, install and maintain, making it practical for line systems that may need service. The stated applications include oil, gas, water and other pipeline systems, including corrosive and non-corrosive service. Select the fitting for the specific tubing and system requirements of your installation.

For a workshop or maintenance project, these tees can help organize a three-way connection without substituting a straight connector. The matching 5/16" OD size across all three ports keeps the junction consistent, while the two-piece quantity is useful when planning more than one connection point. The brass body and compression format are the defining features to consider when comparing this style with other tube-fitting designs.

Questions before you buy

What tubing size does this tee fit? Each of its three connections is listed for tubing with a 5/16" outside diameter. Match the tubing’s OD to that measurement when choosing the fitting.

Can it be used with copper or plastic tubing? Yes. The product information identifies both copper and plastic tubing for use with this compression tee union.

What does the compression assembly consist of? The described assembly includes a nut, sleeve and body. Together, these are the components used in the compression fitting.

Is it worth it?

This set is suited to projects that need brass three-way compression junctions for matching 5/16" OD tubing. Its two-piece format, compatibility with copper or plastic tubing and stated range of pipeline applications make it a practical fit for planned line connections and maintenance work. Choose it when a tee layout, rather than a straight join, is the right match for the tubing route.
