Altecnic Fill Loop CAP/SEAL YU-JQAL304

This fill loop cap and seal is designed for use with heating system filling loops, providing a straightforward solution for securing the loop after filling and topping up the system. It acts as a replacement or spare part for installers working on boilers or central heating circuits where the original cap or seal may be missing or damaged.

On site, it is typically fitted by heating engineers and plumbers during maintenance or installation work on sealed systems. Ensuring a proper cap and seal helps maintain system integrity by reducing the risk of accidental leaks or contamination once the filling process is completed.
