Plugs, Strainers & Hole Stoppers

Heating engineers understand that the smallest components often dictate the long-term reliability of a boiler repair. Our dedicated selection of replacement plugs, system strainers and hole stoppers provides the essential brassware and durable synthetic fittings required to tackle common maintenance tasks. Strainers play a vital role in capturing suspended debris and preventing magnetite from entering sensitive waterways, protecting both the heat exchanger and the primary circulator. Meanwhile, high-quality hole stoppers and blanking plugs deliver immediate, watertight seals on decommissioned pipework or spare manifold ports. By stocking parts that meet strict OEM specifications, we enable installers to complete their servicing work efficiently and confidently, reducing the risk of call-backs caused by minor leaks or blockages.
