The 20026407 kit is manufactured to original equipment specifications, ensuring correct sizing, material quality, and long-term durability. The gaskets are designed to withstand high temperatures, pressure fluctuations, and exposure to treated heating water, while the valve knobs and levers provide secure grip and precise control. Together, these components help maintain the boiler’s hydraulic and gas-tight integrity, preventing leaks that could lead to pressure loss, reduced efficiency, or potential safety risks.
Over time, gaskets can harden, compress, or deteriorate due to constant heat exposure and system wear, while valve knobs and levers may become loose, cracked, or difficult to operate. These issues can make maintenance more difficult and increase the risk of leaks or improper valve operation. Replacing worn components with this OEM kit restores reliable sealing, improves ease of use for engineers, and helps maintain safe, efficient boiler operation. Installation should always be carried out by a qualified heating engineer to ensure correct fitting, proper sealing, and full compliance with safety regulations.

Standard delivery for all orders over £150 ex-VAT are free of charge.
If we can speed this up, we will, but you can also select Express Delivery when you check out and get your purchase more quickly (usually the next working day, subject to a 1pm cut-off): there is an extra charge for this ranging from £5 to £29.99 depending on the products you are buying.
We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £27.50 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
