304 Stainless Steel Hose Barb Fittings — Taper Thread x Hose Tail Connectors

Match the barb OD to your hose's inner diameter (ID). For example, a 10mm barb fits a hose with a 10mm ID (≈3/8"). When in doubt, measure the hose ID with calipers rather than relying on the hose's nominal size label. A snug fit prevents leaks without requiring excessive clamp force. Barb sizes in this listing range from 6mm (≈1/4") to 50mm (≈2").

These fittings use BSP Taper (BSPT / R Thread) — a widely used standard in plumbing, hydraulics, and pneumatics. Available thread sizes include 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1-1/4", 1-1/2", and 2". BSPT threads are self-sealing by design; PTFE tape is generally recommended for a leak-free joint in liquid service.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor, humid, and mildly corrosive environments. It is generally suitable for water, air, and light chemical service. For highly chlorinated water, saltwater, or aggressive chemical exposure, 316 stainless steel is typically recommended instead.

Working pressure varies by fitting size, wall thickness, and the hose assembly used. 304 stainless steel hose barb fittings in these size ranges are typically suitable for moderate-pressure water, air, and fluid transfer lines. Contact us to confirm the pressure rating for your specific size and application before use in high-pressure systems.

For low-pressure or gravity-fed systems, a push-fit connection may hold adequately on its own. For pressurized lines, a stainless steel hose clamp is generally recommended to secure the hose over the barb and prevent blow-off under pressure or vibration. Clamps are not included.

• Male Straight / Female Straight — Connect a hose to a threaded port on a pump, valve, or manifold.
• Male 90° Elbow — Route hose around a corner or tight space without kinking.
• T Piece — Split one flow into two, or merge two flows into one (equal diameter).
• Y Piece — Similar to T Piece but with an angled branch for smoother flow splitting.
• Straight (push-on barb) — Join two hoses of the same diameter inline without a threaded port.
• Straight Reducer — Connect two hoses of different inner diameters inline.

PTFE (thread seal) tape is generally recommended for BSPT taper thread fittings, especially in liquid service, to ensure a leak-free seal. Apply 2–3 wraps in the direction of the thread before installation. In most cases, no additional sealant compound is needed.
