Frequently Asked Questions:
How do I know which gasket variant I need?
Check the code on your existing gasket or measure its profile carefully. If you're unsure, we recommend purchasing our Gasket Sample Pack first to compare profiles and ensure the perfect match for your E Gasket/Fir Tree Gasket needs.
Can I install this gasket myself?
Absolutely! E Gaskets are designed for simple push-fit installation without any special tools or adhesives. Simply push the gasket into the existing groove around your window or door frame.
What's the difference between EPDM and TPR gaskets?
EPDM gaskets offer excellent compression recovery and maintain performance in extreme temperatures, making them ideal for frequently opened windows and doors. TPR gaskets provide superior resistance to oils and fluids while being highly flexible and abrasion-resistant.
How long will the gasket last?
With proper installation, both EPDM and TPR gaskets typically last 7-10 years. Both materials are UV stable and ozone resistant, ensuring they maintain flexibility and performance through changing seasons.
Why Choose Reddiplex E Gasket?
Reddiplex gaskets represent the gold standard in window and door sealing solutions. By choosing these professional-grade gaskets, you're investing in a simple yet effective upgrade that will eliminate draughts, prevent leaks, and improve the overall comfort of your home.
