Stainless Steel Bulkhead Barb Fitting — Barbed Hose Tail Connector & Tube Coupler Adapter

Match the barb diameter to your hose's inner diameter (ID). For example, a 1/2" (≈12.7mm) barb fits a hose with a 1/2" ID. The bulkhead thread size determines the hole you need to drill in your tank — typically the hole is drilled slightly larger than the thread OD. When in doubt, measure your hose ID and tank wall thickness before ordering.

Stainless steel bulkhead barb fittings generally handle moderate working pressures suitable for gravity-fed systems, low-pressure water transfer, and brewing setups. Exact pressure ratings depend on the specific size and wall thickness. Contact us to confirm ratings for your application before use in pressurized lines.

Yes. Stainless steel construction provides strong resistance to rust, oxidation, and mild chemical exposure, making these fittings suitable for outdoor rainwater tanks, garden irrigation, and light industrial use. For highly corrosive media or saltwater immersion, contact us to confirm the specific grade before ordering.

Thread standard varies by variant. These fittings are typically available in BSP (British Standard Pipe) or NPT (National Pipe Thread) depending on the size selected. Check the variant description carefully, or contact us with your existing fitting's thread type to confirm compatibility before purchase.

Stainless steel is widely used in food and beverage processing due to its non-reactive, easy-to-clean surface. These fittings are generally suitable for homebrewing, fermentation tanks, and food-safe water transfer. Always verify the specific grade and finish meet your local food-safety requirements for your intended use.

Most bulkhead fittings are designed to be used with a rubber or silicone gasket/washer to create a watertight seal against the tank wall — check your variant to confirm what's included. For the threaded connections, PTFE (Teflon) tape is generally recommended on the threads to prevent leaks. For pressurized hose connections, a stainless hose clamp over the barb is advised.

Barbed fittings work with flexible hoses including PVC, silicone, rubber, and polyurethane tubing. The hose inner diameter should match the barb diameter for a secure, leak-resistant connection. For any pressurized application, always secure the hose with a clamp over the barb to prevent blow-off.

Drill a hole in the tank wall sized to the fitting's thread OD (typically a step drill or hole saw works well for plastic). Insert the fitting from the outside, place the gasket against the tank wall, and thread on the lock nut from the inside — hand-tighten, then snug with a wrench. Do not overtighten on thin plastic walls. Attach your hose to the barb and secure with a clamp.
