304 Stainless Steel Barbed Tee Hose Connector — T-Piece Hose Fitting 8mm to 32mm

Match the barb OD (outer diameter) to your hose's inner diameter (ID). For example, an 8mm (≈5/16") barb fits a hose with an 8mm inner bore; a 16mm (≈5/8") barb fits a 16mm ID hose. The hose should stretch slightly over the barb for a secure grip. If your hose ID falls between two sizes, size down for a tighter, more leak-resistant fit. Always measure the inside bore of your hose — not its outer wall — before ordering.

Working pressure depends on hose type, clamp method, and barb size. In general, stainless steel barbed fittings used with hose clamps on reinforced hose can handle moderate pressures — typically up to 60–150 PSI depending on the application and hose rating. For high-pressure systems, confirm compatibility with your hose and clamp specifications before use. Contact us for guidance on specific pressure requirements.

Yes. Stainless steel barbed tee fittings are well-suited for outdoor and wet environments, including garden drip irrigation systems, outdoor cooling loops, and exposed plumbing runs. They resist rust and oxidation significantly better than zinc alloy or plastic alternatives in humid, wet, or UV-exposed conditions. For marine or saltwater environments, confirm grade suitability before use.

These barbed tees are compatible with most flexible hoses including silicone, rubber, PVC, and polyurethane hoses, provided the hose inner diameter matches the barb OD. They are not designed for rigid pipe or threaded connections. Always verify that your hose material is compatible with the fluid being carried (water, coolant, air, fuel, etc.) before installation.

For low-pressure or gravity-fed applications (such as drip irrigation), a push-on fit may be sufficient. For any pressurized system — automotive cooling, compressed air, or pressurized water lines — using stainless steel hose clamps over each barb is strongly recommended to prevent blowoff under pressure. The barbed profile grips the hose mechanically, but clamps provide the additional retention needed in pressurized service.

The barb OD (outer diameter) is the measurement across the tip of the fitting's barb. The hose ID (inner diameter) is the measurement of the inside bore of your hose. These should match — or the barb OD should be very slightly larger than the hose ID for a snug, leak-resistant fit. Always measure your hose ID (the inside opening), not its outer wall thickness. A caliper or ruler inserted into the hose end gives the most accurate reading.

Stainless steel is generally compatible with many fuels and mild chemicals. However, compatibility depends on both the fitting material and the hose material. Always verify that your hose is rated for the specific fluid (fuel, coolant, solvent, chemical) before use. For aggressive media or high-temperature applications, contact us to confirm suitability before ordering.
