GBGreat product
Great product especially when you have 10mm radiator pipes and the radiator has 15mm valves. Easy to fit and solder and a quality product. I have found these a little difficult to source but on demand supplies always has them. Would recommend

GBMatching existing valve.
I wanted to match the existing valve due to its awkward position of pipework. Found this item online and your ease of ordering, delivery time and communication was excellent. If, or rather when I need anything else I will be checking your site first. First class service
