The Precision I (HF905)I (HF907) Glass Seal is a genuine Hi-Flame spare part for the Precision 2. Self-adhesive and rated for high-temperature use, the 3mm rope applies directly to the glass channel in the door frame. Replacing a deteriorated glass seal stops air bypass, restores the airwash system, and keeps the glass clear during operation. Simple to fit and an important part of a well-maintained stove door.
