RUBASIA RUBBERTECH’s Edge trim rubber with a side bulb and internal metal reinforcement is a versatile, push-on sealing profile used to cover sharp edges while simultaneously creating a watertight, dust-proof seal. The U-shaped PVC or rubber base features internal metal clips for a secure, adhesive-free grip, while the attached soft sponge EPDM bulb seals gaps on doors, hatches, and panels. 

Key Characteristics and Functions: 

• Structure: Comprised of a durable, flexible PVC or EPDM grip section with internal steel wire or metal clips for "self-gripping".
• Side Bulb: A soft, sponge EPDM rubber tube (or "bulb") is attached to the side, which compresses when closed to seal against water, air, noise, and vibration.
• Installation: Simply pushed onto raw edges of metal, wood, or fiberglass, requiring no adhesive or screws.
• Durability: Highly resistant to weather, ozone, UV, and temperature extremes.
• Applications: Commonly used as car door seals, truck, boat hatch seals, cabinets, and container door seals. 

These are often used in automotive, marine, and industrial applications to prevent leakage and protect against damage.
