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.

Choosing and fitting

Pressure switches of this type are selected based on the required setting range, switching differential, and maximum working pressure. The medium must be compatible with the switch materials. Installation can be direct on the pressure line or on a flat surface using two screws. Ensure the switch is mounted in the specified operating position to maintain the stated protection class.

Signs of failure

Common failure modes for mechanical pressure switches include leakage, contact welding, or drift in the setpoint. Symptoms may include failure to switch, erratic operation, or the system not responding to pressure changes. Check for physical damage, contamination, and verify the setpoint with a calibrated gauge.
