6mm~50mm Stainless Reducer Barbed Hose Joiner Connector Air Water Pipe Gas Tubi

The variant size is listed as Outer Barb mm – Inner Barb mm. The first number is the outer diameter of the larger barb end; the second is the outer diameter of the smaller barb end. To match your hose, measure the inner diameter of each hose — the barb OD should be equal to or very slightly larger than the hose ID to create a secure interference fit.

These fittings are designed for flexible hoses including PVC garden hose, rubber air hose, silicone coolant hose, and braided fuel line. They are not intended for rigid pipe or push-fit plumbing systems. Always verify that your hose material is compatible with the fluid being conveyed (e.g., fuel-rated hose for petrol/diesel applications).

For low-pressure gravity-fed water or drip irrigation applications, the barb grip alone is often sufficient. For any pressurized system — including compressed air, mains water, or fuel lines — securing each hose end with a worm-drive or ear clamp is strongly recommended to prevent blow-off under pressure spikes.

Yes. Stainless steel resists surface rust and corrosion from rain, soil moisture, and UV exposure far better than plain steel or zinc-plated fittings. For buried or permanently submerged installations, confirm the specific grade is appropriate for your soil chemistry; contact us if you need grade confirmation.

Select the quantity that matches your project scope. A single fitting suits a one-off repair. A 3- or 5-pack is practical for a drip irrigation layout with multiple branch points. A 10-pack offers the lowest per-unit cost and is suited for workshop stock or larger plumbing runs where the same reducer size is used repeatedly.

Yes, for typical workshop compressed air pressures (up to approximately 8–10 bar / 120–150 psi) when used with appropriate air hose and secured with hose clamps. For higher-pressure industrial pneumatic systems, contact us to confirm suitability for your specific operating pressure and hose wall thickness.
