Brass Compression Tee Fitting — Reliable T-Piece Connector for Plumbing & Fluid Systems
When a leaking joint or a mismatched fitting brings your plumbing project to a halt, you need a connector you can trust. Whether you're a DIY homeowner splitting a water line, a tradesperson routing pneumatic tubing, or a workshop builder assembling a compressed air system, a poorly made tee fitting is the last thing you want mid-job. These brass male compression tee fittings are built to give you a secure, leak-resistant connection the first time.
Each piece is a T-shaped compression fitting machined from solid brass, featuring three ports — two inline run ports and one branch port — secured by compression nuts that grip the pipe OD without soldering or adhesive. Available in equal tee configurations from 6mm (≈1/4") up to 19mm (≈3/4"), and in reducing tee sizes with branch ports of 1/8", 1/4", or 1/2". Order in quantities of 1, 3, 5, or 10 pieces to suit single repairs or larger installations.
Typical applications include domestic water supply branching, garden irrigation manifolds, pneumatic airline distribution, and copper or nylon tube assemblies in cabinetry and furniture manufacturing — making these brass compression tee connectors a versatile addition to any toolbox or parts bin.

Compatibility: Designed for use with copper, nylon, polyethylene (PE), and semi-rigid plastic tubing. Match the fitting size to your pipe's outer diameter (OD). Not recommended for standard PVC pressure pipe. Confirm pipe OD before ordering.
✅ Key Features of These Brass Compression Tee Fittings
-
🔩Solid Brass Construction — Machined from brass for durability, corrosion resistance, and reliable performance in water, air, and light fluid systems.
-
🔀Equal & Reducing Tee Options — Choose equal tees (6mm–19mm) or reducing tees with 1/8", 1/4", or 1/2" branch ports to match your specific branch line size.
-
🛠️Tool-Friendly Compression Fit — No soldering or special equipment needed; a standard wrench is all it takes to achieve a secure, leak-resistant joint on copper or plastic pipe.
-
📐Wide Size Range — Available from 6mm (≈1/4") to 19mm (≈3/4") to cover the most common pipe sizes used in residential plumbing and pneumatic tubing applications.
-
📦Flexible Quantity Options — Order 1, 3, 5, or 10 pieces per SKU, so you only buy what you need — ideal for single repairs or stocking a parts inventory.
-
💧Flared Seat Design — The flared compression seat creates a positive mechanical seal, reducing the risk of joint failure under vibration or pressure fluctuation in plumbing and air line installations.

Note: Always verify your pipe's outer diameter (OD) before ordering. Compression fittings seal on the pipe OD — using the wrong size will result in leaks. If you are unsure, contact us before purchasing.
❓ Frequently Asked Questions
How do I choose the right size compression tee fitting?
Match the fitting size to your pipe's outer diameter (OD). For example, a 6mm fitting suits pipe with a 6mm OD. For reducing tees (e.g. 6mm × 1/4" × 6mm), the middle dimension is the branch port size — choose this based on your branch line pipe OD. When in doubt, measure your pipe OD with calipers before ordering.
What pipe types are compatible with these compression tee fittings?
These fittings are generally compatible with copper, nylon, polyethylene (PE), and semi-rigid plastic tubing. They are not typically recommended for standard PVC pressure pipe or corrugated flexible hose. Always confirm your pipe's OD and wall thickness before installation.
Can these fittings be used outdoors or in wet environments?
Brass offers good corrosion resistance and is generally suitable for outdoor and damp environments. In highly saline or chemically aggressive conditions, additional protection or alternative materials may be advisable. Contact us to confirm suitability for your specific application.
What is the pressure rating of these compression tee fittings?
Brass compression fittings typically handle working pressures in the range of 10–16 bar (145–232 psi) depending on size and pipe type. Exact ratings vary by variant — contact us to confirm the pressure rating for your specific size before use in high-pressure systems.
What thread standard do the male ports use?
The male threaded ports on these fittings generally conform to BSP (British Standard Pipe) or metric thread standards depending on the variant. Please check the size description or contact us to confirm the thread type for your chosen size to ensure compatibility with your existing fittings.
Do I need any tools or sealant to install these fittings?
Compression fittings are generally tool-friendly — a wrench is typically sufficient to tighten the compression nut onto the pipe. PTFE tape or thread sealant is recommended on male threaded ports to ensure a leak-free seal. No soldering or special equipment is required, making these suitable for DIY installation.
What is the difference between an equal tee and a reducing tee in this listing?
Equal tees (e.g. 6mm × 6mm × 6mm) have all three ports the same size, ideal for splitting a single line into two equal branches. Reducing tees (e.g. 6mm × 1/4" × 6mm) have a smaller branch port, allowing you to tap off to a smaller pipe or fitting. Choose based on your branch line pipe OD.
Can I reuse these compression fittings after disassembly?
Brass compression fittings can in many cases be disassembled and reused, particularly when used with copper pipe. However, the compression ring (olive) may deform slightly during initial installation. In most cases it is advisable to use a new olive when reassembling to ensure a reliable seal. Contact us if you need replacement olives.
