Female Run Tee Pipe Fitting: High-Integrity Branch Connector

(Male/Female Run Tee with Male Branch or 3-Way Adapter Tee)

Create a multi-functional connection point at the end of your pipe run. The Stark Street Run Tee is a unique, problem-solving fitting featuring one female run port, one male run port, and a male branch port. This combination allows it to serve as both an extension and a branching point. Machined from a single piece of forged 316/316L stainless steel, it is the ideal choice for creating compact instrument clusters at the end of a line or for transitioning between different piping components.

🛠 The Engineering Advantage

Integrated Design Reduces Components: This single fitting can replace a standard tee, a close nipple, and a bushing, reducing the number of components and potential leak paths in your system. It's a smarter, more integrated approach to piping design.

Superior Strength with One-Piece Forging: Unlike multi-piece assemblies, our street run tees are machined from forged 316L stainless steel. This provides a superior grain structure that offers higher strength and resistance to cracking under high pressure and installation torque.

Ideal for End-of-Line Instrumentation: The unique M x F run design allows you to install the tee directly onto the end of a male pipe run, providing a secure branch for a gauge or sensor, while simultaneously offering a male-threaded outlet for further connections.

Guaranteed Material Integrity: Every Stark pipe fitting comes with full material traceability. We provide a Material Test Report (MTR) to EN 10204 3.1 and PMI verification as standard, giving you absolute confidence in the material you are installing.

📌 Targeted Application Support

End-of-Line Instrument Clusters: The perfect fitting for mounting a pressure gauge and a temperature sensor at the end of a pipe run.

Compact Manifold Building: Use multiple street run tees to create compact, custom distribution or collection manifolds.

System Transitions: Provides a versatile connection point for transitioning from a male-threaded pipe to a different size or connection type.

Air Compressor & Pneumatic Lines: Ideal for creating take-off points for regulators, filters, and lubricators.

❓ Frequently Asked Questions (FAQ)

Q1: What is a "Street Run Tee"?

A "Street" fitting is an industry term for a fitting that has both male and female threads. A "Street Run Tee" therefore has a combination of male and female threads on its straight-through "run" ports, plus a branch port. Our specific design features one female run, one male run, and one male branch.

Q2: Do I need to use thread sealant on all three ports?

Yes.You will need to apply a high-quality thread sealant to all male threads involved in the connection: the male run port, the male branch port, and the male pipe or fitting that you install into the female run port.

Q3: Can the branch port be a different size than the run ports?

Absolutely. We offer a wide range of reducing configurations where the branch port is smaller than the run ports (e.g., 1/2" run x 1/4" branch). This is ideal for instrument take-offs.

Q4: How does this fitting save space compared to a standard tee?

By integrating a male thread directly into the body, it eliminates the need for a separate "close nipple" fitting. This results in a much more compact, shorter, and structurally robust installation.
