BSM Union Blank Cap

The BSM Union Blank Cap is a precision-engineered pipe termination component designed to blank off and seal the open end of a BSM union assembly in hygienic and industrial piping systems. Manufactured from 316-grade stainless steel, this blank cap provides a reliable, hygienic, and corrosion-resistant closure solution, making it an essential fitting in food processing, pharmaceutical, dairy, beverage, and other process industry piping applications where pipe ends require secure termination.

As clearly visible in the product image, the blank cap presents a shallow, disc-shaped form with a flat central face and a defined outer rim or lip around its circumference. This rimmed edge profile is designed to seat accurately within the corresponding union nut assembly, allowing the blank cap to be secured in place using the union hex nut to create a complete and sealed pipe end termination. The flat, unperforated face of the cap provides the blanking surface that closes off the pipe end entirely, preventing flow, contamination ingress, or pressure loss at the termination point. The surface finish visible in the image is consistent with the smooth, clean properties associated with 316-grade stainless steel.

The blank cap is commonly used to temporarily or permanently close off pipe ends during system modifications, maintenance periods, or where a pipeline branch or outlet is not currently in service. Its compatibility with the standard BSM union system ensures straightforward installation and removal without the need for specialist tooling.

The BSM Union Blank Cap is available across eight sizes: 25mm, 38mm, 51mm, 63mm, 76mm, 101mm, 127mm, and 152mm, ensuring precise compatibility with the full range of standard BSM union assemblies and pipe diameters used across hygienic and industrial piping installations.

316-grade stainless steel provides superior corrosion resistance and supports effective cleaning and sterilisation procedures essential in hygiene-critical environments.
