Restore a tight, reliable seal on your Jotul wood stove or insert with this 9 mm Old Black fiberglass rope gasket, available in convenient 5-foot and 7-foot lengths. Designed to flex easily around stove door contours while holding up to serious heat, this gasket helps prevent air leaks that waste fuel and reduce efficiency.
Made from graphite-impregnated fiberglass, it’s built for durability and long service life, with a 1000°F (538°C) temperature rating. The premium, non-asbestos construction resists fraying when cut, won’t absorb moisture, and stands up to mildew—so installation is clean and performance stays consistent.
Preparation: Remove the old gasket, clean the channel thoroughly, and allow it to dry.
Application: Secure the new gasket using stove gasket cement. Our recommended cements bond the gasket firmly while also sealing minor cracks and pinholes in the stove body.
Important: Do not use high-temperature silicone sealants for gasket installation or stove repairs.
Diameter: 9 mm
Lengths Available: 5 ft, 7 ft
Color: Old Black
Material: Graphite-impregnated fiberglass rope
Temperature Rating: Up to 1000°F (538°C)
SKU: STK-3/8-RND-GSK
If your stove requires an extra gasket, just adjust the quantity to reach the total length.
• 15 ft = select the 5-ft option, quantity 3
• 21 ft = select the 7-ft option, quantity 3
I’ll send continuous lengths whenever possible, so installation stays smooth and frustration-free.
Check your stove’s manual or manufacturer part number if available.
Measure the width and depth of the gasket channel and choose the size that best fills it.
Measure the old gasket length and order slightly longer—you can trim for a perfect fit.
Note that gasket sizes may be listed in millimeters or inches (9 mm is close to 3/8").
