DDR BBQ Supply Smoker Gasket Sealer – 15 ft, 1/2" x 1/8" is the simple, effective solution for stopping unwanted smoke leaks and improving heat retention in your smoker or grill. This durable gasket helps create a tighter seal, leading to more consistent cooks, better temperature control, and improved fuel efficiency.
Why You’ll Love It- Eliminates smoke leaks: Fills door gaps so flavorful smoke stays inside your smoker where it belongs.
- Improves heat retention: Helps maintain steady cooking temperatures for predictable, repeatable results.
- More fuel efficient: Reduces pellet, charcoal, or wood usage by minimizing heat loss.
- Durable construction: Built to last through repeated cooks and long smoking sessions.
- Generous length: Includes 15 feet of gasket material—enough for most smoker doors.
- Length: 15 feet
- Dimensions: 1/2" width x 1/8" thickness
- Material: Long-lasting gasket material designed for smoker and grill use
- Use: Fits most smokers and grills (always measure door gaps for best results)
- Thoroughly clean and dry the door surface before installation to ensure strong adhesion.
- Test-fit the gasket around the door before removing the backing so you know exactly where to place it.
- Apply firm, even pressure along the entire length after installation to help it seat properly.
- Let the gasket sit for a bit before your next cook so the adhesive can bond well.
Will this fit my smoker?
Yes. It’s designed to work with most smoker doors, but for best results, measure your door gap and confirm the dimensions match the 1/2" x 1/8" profile.
How do I install it?
Clean and dry the surface, peel off the backing, and press the gasket firmly along the door edge. Trim to size with scissors or a utility knife as needed.
Is it reusable?
No. Once installed and used, it is designed to remain in place for long-term performance and should not be removed and reused.
Can it handle normal smoking conditions?
Yes. It is specifically designed for typical smoker and grill environments and regular BBQ use.
Will it help save fuel?
Yes. By sealing gaps and reducing heat loss, your smoker uses less fuel to maintain cooking temperatures over the course of a cook.

With over 35 years of smoking experience, we started DDR BBQ Supply with a simple goal: to help others cook better barbecue. We've spent decades learning what works and what doesn't, and we apply that knowledge to every product we carry. From high-performance grills and smokers to carefully selected rubs, sauces, and tools, everything we offer is something we believe in and use ourselves. We don’t believe in cutting corners or selling gear we wouldn’t rely on during our own backyard cooks and when we compete in BBQ competitions.
