A worn door gasket can quietly sabotage your wood stove’s performance. This Harman Wood Stove Door Gasket Kit is designed to bring your stove back to peak efficiency with a tight, reliable seal that holds up to real heat.
This kit includes 7 feet of 3/8" round fiberglass rope gasket, infused with black graphite for added durability, flexibility, and heat resistance. It creates a strong, air-tight seal that helps regulate airflow, improve burn efficiency, and keep heat where it belongs—inside your stove. Rated for temperatures up to 1000°F, this gasket won’t unravel, fray, or harden over time.
The fiberglass rope easily conforms to curved door channels and bonds securely to most stove materials using the included gasket cement. It’s non-asbestos, environmentally friendly, moisture-resistant, and won’t absorb water or grow mildew—exactly what you want in a long-lasting stove repair.
7 ft. of 3/8" fiberglass rope gasket
Stove gasket cement for secure installation
Preparation:
Remove the old gasket, clean out the channel, and ensure the surface is dry.
Application:
Apply gasket cement evenly in the channel and press the new gasket firmly into place. Trim excess length as needed. The cement not only holds the gasket securely but also helps seal small cracks or pinholes in the stove body.
Important:
Do not use high-temperature silicone sealants for gasket installation or stove repairs—they won’t hold up properly and can cause future leaks.
Getting the right size matters. Here’s how to be sure:
Check your stove’s manual for the correct replacement gasket size or part number
Contact Harman directly if you’re unsure
Measure the width and depth of the gasket channel and choose the larger measurement
Measure the length of the existing gasket and allow extra length for trimming
Common wood stove gasket sizes include:
3/16”, 1/4", 5/16”, 3/8”, 7/16”, 1/2”, 5/8”, 3/4”, 7/8”, and 1”
If you’re still unsure, use our free printable gasket measuring template to find the perfect fit—no guesswork required.
A fresh gasket is one of the easiest ways to improve stove efficiency, heat output, and safety. This Harman gasket kit gets it done right the first time.
