## Summary description

Bottom connection unit Sourcing 11PK designed for radiators sized 500×1000 mm. Provides a lower inlet/outlet connection point for installation and plumbing of panel or convector radiators.

## Long description

The Sourcing 11PK radiator bottom connection is engineered for use with 500×1000 mm panel and convector radiators to provide a concealed lower inlet/outlet. This unit enables plumbing to be routed through the bottom of the radiator, offering a tidier installation and compatibility with installations where side connections are impractical. The assembly is designed to match the physical dimensions of standard 500×1000 radiators and to integrate with existing mounting arrangements without altering radiator performance.
Advantages
The bottom connection simplifies pipe routing by relocating the inlet and outlet to the underside of the radiator, reducing visible pipework and improving the visual appearance of the installation. It allows for straightforward replacement or retrofitting of an existing radiator connection without requiring major modifications to the radiator body. The unit is produced to align with the specified radiator size, supporting consistent flow and sealing when fitted correctly.
Suitable for
Domestic and commercial radiators sized 500×1000 mm
Installations requiring concealed or underfloor pipework
Retrofit projects where side connections need to be replaced
Applications demanding a neat finish around the radiator base

How to use
