Description
Overview:
This BSPP Female Flanged Backnut 1" is a solid brass fastener for building secure, leak‐resistant joints on diesel and fuel equipment. It features a British Standard Pipe Parallel (BSPP) female thread in 1 inch size (25.4 mm) and a flanged collar to spread load and improve sealing. Used to clamp fittings through tank walls, panels or bulkheads, it helps maintain system integrity on transfer pumps, filter heads, valves and pipe unions. Brass offers good corrosion resistance in contact with fuels and outdoor conditions, making it a dependable choice for plant, agricultural, generator and workshop fuel systems. The flanged design supports easy installation with a flat gasket or washer, providing a stable, long‐lasting connection in new builds, upgrades, and maintenance work.
