Key Features & Benefits

· Excellent Oil & Fuel Resistance: Made from Nitrile rubber, which offers superior resistance to oils, greases, and fuels preventing degradation and ensuring long-term sealing integrity.

· Easy Peel-and-Stick Installation: Features a strong, ready-to-use acrylic adhesive backing. Simply peel the liner and press into place for a instant, secure, and permanent bond, eliminating the need for additional glues or tools.

· Effective Sealing & Cushioning: Vibration Damping-Absorbs shocks and vibrations between body panels, reducing noise and providing a quieter ride; Weatherproof Effectively blocks out dust, water, and wind, protecting the vehicle's interior; Thermal insulation-Provides a degree of thermal insulation, contributing to cabin comfort.

· Durable & Flexible: The closed-cell sponge structure ensures excellent compression set recovery, meaning the seal returns to its original shape after repeated compression, maintaining a tight seal overtime.

· Universal Application: Perfect for sealing car and truck doors, hoods, trunk lids, and fenders. Also widely used in machinery, electrical cabinets, and other industrial equipment requiring oil-resistant sealing.

FAQ:

Q: What is the main advantage of NBR over EPDM?

A: The primary advantage is its superior resistance to oils, fuels, and solvents. EPDM is better for weather and ozone resistance, but swells in oil. Choose NBR for engine bays or are as exposed to petroleum products.

Q: How should the surface be prepared before installation?

A: For maximum adhesion, ensure the surface is clean, dry, and free of grease, oil, and dust Wiping with isopropyl alcohol is highly recommended.

Q: Can l request a sample for testing?
