Grant Cleaning Door Rope – WPS43 (Was WPS102)

Genuine High-Temperature Rope Seal for Grant Spira Biomass Boiler Cleaning Doors

The Grant WPS43 Cleaning Door Rope is a genuine replacement high-temperature rope gasket designed to seal the cleaning access door on Grant Spira biomass boilers. Formerly supplied as WPS102, this part ensures a tight, heat-resistant seal around the cleaning door, preventing flue gas leakage and maintaining efficient, safe operation of the boiler.

Over time, the rope seal can become worn, brittle, or compressed from regular maintenance and high-heat exposure. Replacing it with the WPS43 ensures your boiler continues to operate safely and in line with manufacturer guidelines.
