SPE Series Stainless Steel Union Tee Fittings

Features & Key Specifications

Features & Key Specifications of Our SPE Series:

Standard T-Junction for Tubing:

The union tee is the most common way to join three tubes, allowing a single air source to be split into two lines at a 90-degree angle.

Convenient Mounting Hole:

A pass-through hole in the center of the fitting allows it to be securely fastened to a machine frame or panel with a screw, providing extra stability and creating a neat, professional installation.

Premium Stainless Steel Construction:

Available in both 304 and 316 stainless steel, these fittings offer exceptional resistance to corrosion, chemicals, and high temperatures.

Comprehensive Size Options:

We stock a full range of sizes to fit any system.

Tube OD (Metric): 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm

Tube OD (Inch): 5/32", 1/4", 5/16", 3/8", 1/2"

Food-Grade & Oil-Free Design:

Manufactured to be oil-free and compliant with the Food Hygiene Law, our food grade tee fittings are safe for use in sanitary applications.

Application Fields

The Standard for Creating 90-Degree Branches:

Splitting Air Supplies: Branching a main air line to power two separate pneumatic circuits or devices.

Machine Building: Creating clean and organized pneumatic layouts on automated machinery.

Food & Beverage Processing: A hygienic stainless steel tee for connecting tubing on processing and packaging lines.

Laboratory & Instrumentation: Creating multiple sample or carrier gas lines from a single source.

Technical & Selection Guide

Union Tee (SPE) vs. Union Y (SPYX): Which to Choose?

Choose this Union Tee (SPE) if: You need to create a classic 90-degree branch from a main line, which is the most common requirement.

Choose a Union Y (SPYX) if: Your tubing layout would benefit from splitting the line at a 45-degree angle, which can sometimes provide a smoother flow path and a more compact fit.

The mounting hole on the SPE Union Tee also offers superior stability for fixed installations.

FAQ

Frequently Asked questions

Q: What is a "union tee"?

A: It's a T-shaped fitting that connects a tube on all three ends. It is used to split one line into two or join two lines into one.

Q: How do I use the mounting hole?

A: You can use a standard screw or bolt that fits through the center hole (diameter 'N' on the datasheet) to fasten the fitting directly onto a flat surface, such as a machine panel or a mounting rail.

Q: Are all three ports the same size?

A: Yes, the SPE is an equal union tee, meaning all three push-in ports are designed for the same tube diameter.
