ACV Rope fibreglass 51700025

ACV Rope fibreglass 51700025 is a sealing cord used for doors and covers in ACV boilers. It is 10 mm in diameter and sold per meter. This gasket ensures the boiler enclosure remains airtight and thermally efficient. It is compatible with ACV Prestige 50 MK2, Prestige 75 MK2, HeatMaster 71, HeatMaster 101, and CA 300 Classic models.

When replacing a rope gasket of this type, ensure the diameter matches the original (commonly 10 mm or 12 mm) and the material is suitable for high temperatures. Measure the groove length to order the correct length, as the cord is typically cut to size. The gasket should be fitted evenly into the groove without stretching, and the door or cover should close securely to maintain a proper seal.

Over time, rope gaskets can become brittle, frayed, or compressed, leading to air leaks. Symptoms include reduced boiler efficiency, increased fuel consumption, or visible soot around the door or cover. Check the gasket for wear, cracks, or gaps, and replace it if it no longer provides a tight seal.
