Sanitary Stainless Steel Hose Coupling Coupler Connector Hose Fittings

304/316L Sanitary Hose Barb Adapter (Tri-Clamp / Weld Fitting)

Securely connect your flexible fluid-transfer hoses to your rigid sanitary pipeline systems with the Aomite Sanitary Hose Barb Adapter.

Also known as a hose tail or hose coupling, this vital fitting features a stepped, ridged barb on one end to grip flexible silicone or braided hoses tightly, preventing blow-offs under pressure. The opposite end is precision-machined with a standard Tri-Clamp flange (Weld and Thread ends also available) for quick, tool-free integration into your existing equipment. Forged from premium AISI 304 or AISI 316L stainless steel and finished with a high-gloss mirror polish, it ensures a 100% hygienic, crevice-free transition. Fully compliant with DIN, 3A, SMS, and ISO/IDF standards, we support bulk orders for sizes ranging from 1/2" to 4".

How do I size the Tri-Clamp end of the hose adapter correctly?

Matching the Flange (Dimension "K")
When selecting a hose adapter, the inner diameter (Φ) matches your hose, but the flange outer diameter (Dimension "K" in our technical drawing) must match your existing Tri-Clamp ferrule. For example, a 1/2" and 3/4" fitting often share the same 25.4mm or 50.5mm (K) flange face. Always verify the "K" dimension in our specification table to ensure your clamp and gasket will form a leak-proof seal.

Why does the hose adapter have a ridged (barbed) design?

Grip and Friction: The stepped ridges bite into the inner wall of soft silicone, rubber, or PVC hoses. This prevents the hose from slipping off when fluid is pumped through at high velocities.
Clamp Seating: The flat valleys between the ridges provide a perfect resting place for external worm-gear hose clamps or Oetiker clamps, securing the hose permanently to the stainless steel fitting without cutting the rubber.
