What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Further details

Application context	seals the burner-heat exchanger joint, ensuring safe and efficient boiler operation
Key benefits	Leak-proof seal, wear resistance, factory original quality
Material composition	EPDM, silicone, graphite or fibre (material depends on temperature and medium rating)
Material function in system	contains water, gas and flue gases within their intended circuits, and protects precision components from contamination or leakage
Replacement selection criteria	must match original in shape, thickness, material grade, and for a kit, the exact assembly series
Risks of incorrect replacement	incorrect seal can lead to leakage, combustion imbalance, or safety hazard

Choosing and fitting

When selecting a replacement burner gasket, confirm that the new part matches the original in shape, thickness, and material grade. Common gasket materials include EPDM, silicone, graphite, and fibre, chosen for temperature and medium compatibility. Gaskets are typically located at flanged joints, such as between the burner and boiler front plate. For kits, the replacement must match the exact valve or regulator series; it is not interchangeable with other series.

Signs of failure

Failed or worn gaskets allow gas or water to escape from the burner-heat exchanger joint, causing visible leakage, reduced boiler efficiency, or flame instability. The equipment may show pressure drops, difficulty maintaining ignition, or pooling fluid near the burner base. Inspect the joint for moisture, soot, or corrosion; a damaged gasket typically shows visible cracking, hardening, or separation from its seat.
