Key features Material: SUS 304 Stainless Steel for durability and corrosion resistance Surface: Fine Poishing on exterior surfaces Note: Inside is not poished Thread specification: BSP Female Thread available in 1/2', 3/4', 1', 11/4', 11/2', 2' Why this matters Broad compatibility: The listed BSP female thread sizes cover common piping and hose connections, enabling reliable mating with matching BSP male fittings. Corrosion resistance: SUS 304 stainless steel provides long service life in standard fluid and environment conditions, with low maintenance requirements. Practical finish: The fine polishing on the exterior offers a clean, professional appearance suitable for visible installations. Typical applications Plumbing and water supply lines that use BSP female connections, where a robust stainless steel fitting is preferred. Industrial piping or fluid handling systems requiring stainless steel components with standard BSP threading. DIY projects or repairs where an offtheshelf BSP female connection in stainless steel is needed and the inside surface may not require polishing. How to choose and use Select the size that matches the corresponding BSP male thread in your system (1/2', 3/4', 1', 11/4', 11/2', 2'). Ensure mating components are designed for BSP threading to achieve a proper seal and fit. Be aware that the inside is not polished, which may affect seal compatibility with certain gasket or sealing methods.
