Stainless Steel T Hose Barb Tee Connector — 8mm to 32mm, Water & Gas Pipe Fitting

Match the barb size to your hose's inner diameter (ID). For example, an 8mm barb fits a hose with an 8mm ID. When in doubt, measure the inside of your hose with calipers rather than the outside. Available sizes range from 8mm (≈5/16") to 32mm (≈1-1/4"). If your hose ID falls between two sizes, generally choose the smaller barb for a tighter grip.

Stainless steel hose barb tee connectors generally handle working pressures up to around 150 PSI for water and air lines, though actual ratings depend on hose material, clamp type, and operating temperature. For high-pressure or safety-critical applications, contact us to confirm suitability before installation.

Yes. Stainless steel offers strong corrosion resistance, making these tee connectors well-suited for outdoor, humid, and marine environments. They typically resist rust and oxidation far better than standard carbon steel or zinc-plated fittings, making them a reliable choice for garden irrigation, boat plumbing, and poolside setups.

These barbed tee fittings are generally compatible with flexible hoses including silicone, rubber, PVC, and polyurethane tubing. The barbed profile grips the hose interior on insertion. Always use a hose clamp over the barb for a secure, leak-free seal — especially in pressurized systems.

These connectors are designed for water, air, and low-pressure gas lines. For regulated gas applications (natural gas, propane, LPG), always verify local building codes and confirm the fitting is rated for your specific gas type and pressure before installation. When in doubt, contact us to confirm.

No threading, soldering, or adhesive is required. Simply push the barbed end firmly into your flexible hose until the hose seats past the barbs, then secure with a hose clamp (sold separately). A pair of pliers may help seat the fitting fully into stiffer hoses. Lubricate the barb with a drop of water or soap for easier insertion into tight-fitting hose.

You can choose from 1-piece, 2-piece, or 5-piece packs using the Pack Quantity selector above. Multi-pack options offer better per-unit value for projects requiring multiple branch points, such as irrigation manifolds or multi-circuit coolant systems.

The 12mm barb fits hoses with a 12mm inner diameter, while the 13mm barb fits hoses with a 13mm ID. In practice, 1/2" ID hoses can measure anywhere from 12mm to 13mm depending on the manufacturer and material. Measure your hose ID with calipers to select the correct size — a barb that is too small may slip out under pressure.
