I have the tricky job of marinising a boiler, made by a Dutch manufacturer. The necessary adapters proved extremely difficult to find - almost impossible in the UK, where BSP rules, and metric components, when available at all, are often the wrong thread. Even from mainland Europe the search is difficult, and the availability limited - not to mention the unreasonable expense. AK Valves had a good range of adapters with the ability to chose both the precise metric fitting needed at one end and the precise compression fitting at the other, independently. Brilliant! Not only this, but their prices are very reasonable, and small orders no problem. When you add the fact that every order has been delivered in at most two working days, you have a company that I would highly recommend to anyone in this field. The adapters themselves are good, too, though you would expect this of a Parkair fitment - but the company set-up and customer service is what make my life sooo much easier!
Thank you for your great review.
