This PVCu threaded backnut is designed to secure BSP-threaded fittings through tank walls, panels, or flat surfaces. It is typically used in conjunction with tank connectors, adaptors and threaded fittings to provide a firm mechanical lock on the reverse side of the mounting surface.
Manufactured from corrosion-resistant PVCu, the backnut offers reliable long-term performance in water storage, industrial and general engineering applications. Its robust construction helps maintain a secure fixing without the risk of rust or degradation, making it well-suited to both indoor and outdoor installations.
