304 Stainless Steel Barrel Nipple BSP Male Pipe Fitting — 3/4" & 1" Thread

Measure the gap between the two fittings or components you need to connect. The barrel nipple length should match or slightly exceed that gap. Available lengths range from 10mm (≈3/8") to 50mm (≈2"). When in doubt, choose a slightly longer nipple — it can be adjusted with additional fittings more easily than a short one.

This fitting uses BSP (British Standard Pipe) male threads, available in 3/4" and 1" diameters. BSP threads are widely used in plumbing, HVAC, and industrial piping systems across the US, UK, Australia, and most of Asia. They are generally not compatible with NPT (National Pipe Taper) threads without an adapter — confirm your existing fittings use BSP before ordering.

Yes. 304 stainless steel offers good corrosion resistance in most outdoor and wet environments, including freshwater plumbing, irrigation, and general outdoor use. For highly corrosive environments such as saltwater exposure or aggressive chemical contact, 316 stainless steel is typically recommended.

The pressure rating depends on the specific size and installation conditions. 304 stainless steel BSP fittings of this type generally support working pressures suitable for standard residential and light commercial plumbing applications. Contact us to confirm the rated pressure for your specific size and application before use in high-pressure systems.

304 stainless steel BSP male barrel nipples are commonly used in gas piping systems in many regions. However, always verify compliance with your local building codes and gas regulations before installation. Use an appropriate thread sealant rated for gas applications — standard PTFE tape may not be sufficient for all gas systems.

Yes. For a leak-free connection, apply PTFE (Teflon) tape or an appropriate thread sealant compound to the male threads before assembly. This is standard practice for all threaded pipe fittings and is especially important for pressure or fluid systems. Wrap PTFE tape in the direction of the thread (clockwise when viewed from the end) for best results.

Each order is for 1 piece (1pcs) as indicated in the variant options. If you need multiple pieces, simply adjust the quantity at checkout. Bulk pricing inquiries are welcome — contact us for volume orders.

The thread diameter refers to the nominal pipe size the fitting is designed to connect. A 3/4" BSP fitting is typically used on 3/4" nominal pipe (actual OD approximately 26.4mm / 1.04"), while a 1" BSP fitting suits 1" nominal pipe (actual OD approximately 33.2mm / 1.31"). Always match the fitting size to your existing pipe or valve thread size — measure or check your existing fittings if unsure.
