Description
Designed for connecting press fit pipework to BSP threaded components, this female adaptor provides a reliable and efficient transition within stainless steel systems. It is particularly suited to installations where a parallel threaded connection is required for compatibility with valves, equipment, or existing pipework. Manufactured from 316L stainless steel, it delivers excellent corrosion resistance and long term durability, making it suitable for use across a wide range of commercial and industrial applications.
The precision engineered press connection ensures a secure and permanent joint, while the female threaded outlet allows for straightforward integration with BSP fittings. The M-profile design ensures compatibility with standard press tools, supporting a fast and consistent installation process. With no need for hot works, installation is safer and more efficient, reducing both time on site and associated risks.
An EPDM sealing system (FKM alternative available) provides dependable performance across a broad temperature range, and the integrated leak detection feature ensures any unpressed joints are clearly visible during pressure testing. This allows for quick identification and correction prior to system commissioning. WRAS and DVGW approved, this adaptor offers a durable and practical solution for high performance pipework systems.
