Frequently Asked Questions
Q: How do I know which gasket type I need?
A: Measure the width and profile of your current seal and compare it with the diagrams provided on each product page. If you need help identifying the correct replacement gasket, please contact our technical support team.
Q: What's the difference between Bubble and Flipper gaskets?
A: The primary difference lies in their shape and sealing method. Bubble gaskets have a rounded, bulbous shape that compresses when closed, while Flipper gaskets feature a flat or tapered profile with a thin fin that flips over to create the seal.
Q: Are Qlon gaskets better than standard rubber seals?
A: Qlon gaskets are premium foam-based seals offering superior insulation, better compression recovery, and longer-lasting performance compared to standard rubber alternatives.
Q: Can I fit these gaskets myself?
A: Yes — most gaskets are designed for DIY fitting with no adhesives or special tools required. Simply remove the old seal and push the new gasket into the groove.
Gasket Materials & Their Advantages
Q-Lon Gaskets: Made from polyurethane foam, known for high durability and excellent compression recovery. They bounce back to their original shape after compression, providing long-lasting sealing performance.
TPR Gaskets: Thermoplastic Rubber combines flexibility with strength, offering excellent weather resistance, UV stability, and consistent sealing across wide temperature ranges.
EPDM Gaskets: Synthetic rubber with exceptional weather resistance and longevity. EPDM resists ozone, UV rays, and extreme temperatures, perfect for long-term outdoor applications.
PVC Gaskets: Cost-effective option with good chemical resistance. Lightweight and easy to install, though less flexible in extreme cold compared to rubber alternatives.
