Key Advantages

Excellent Weather and Aging Resistance: Made from high-quality EPDM, it maintains its elasticity over time, resists hardening and cracking in extreme temperatures (-50°C to +130°C), UV rays, and ozone, ensuring a service life of decades.

Excellent Sealing Protection: Provides high-elastic, continuous pressure for a tight seal, achieving IP55, IP66, and even higher protection levels, effectively repelling water, dust, and sound.

Convenient Installation: Unique U-shaped structure: Snaps onto the edge of sheet metal like a cap, making installation simple and effortless, requiring no glue or fasteners, significantly reducing installation time and labor costs. Safe and Reliable: Excellent electrical insulation performance ensures the safety of electrical equipment. Non-toxic, odorless, and RoHS compliant.

Durable and Economical: More resistant to aging than ordinary PVC or silicone sealing strips, it provides long-term sealing protection, reduces maintenance and replacement frequency, and lowers total cost of ownership.
