Hydronic Repair Parts

DK Hardware has an extensive range of hydronic repair parts to help you do the job. Also, our products are of the highest quality and deliver exceptional performance. For example, our Granby Vertical Oil Tank uses a sophisticated five-step process to provide the finest paint finish in the industry. The tank is pre-treated with an iron phosphate cleaning process and then run through a drier to ensure a tight bond between the steel and paint. The tank is then passed through a powder coating process where a beautiful yet tough, weather-resistant coating is applied. Also, we have the Plumbers Edge Key. Designed for opening and closing PE957 hot-water air valves, it has a chrome-plated brass construction for strength and durability. This hot water air valve is suitable for hot water radiators, convectors, and baseboards. Alternatively, you can select the filters on this page to quickly find the product you are looking for.
