Underfloor Heating Manifold Manifolds Blanking Cap - Single

This cap may be fine for general pipework but it is not tall enough to fit on an underfloor heating individual manifold if you want to isolate the flow to a particular zone. Underfloor heating manifolds have a pin that needs to be compressed to isolate the flow, which is done by tightening the cap onto the thread, but this item will not reach the thread. I'm glad I only bought one as a test.
