Side Bulb Pinchweld Seals
Rubber United supplies side bulb pinchweld seals for automotive, commercial vehicle and industrial fabrication projects across South Africa. Our range includes EPDM sealing profiles with foam rubber side bulbs designed for sealing, edge protection and vibration reduction.
These profiles help reduce dust, moisture and noise ingress while also protecting exposed panel edges against wear and damage. In addition, many profiles in this range offer excellent UV and weather resistance, making them suitable for demanding indoor and outdoor environments. Most profiles also feature steel reinforcement for improved grip and long term durability.
The range is supplied in convenient 50 metre rolls for wholesale and industrial use. Furthermore, these sealing profiles are suitable for canopies, trailers, truck bodies, automotive panels and industrial enclosures.
What are Side Bulb Pinchweld Seals?
Side bulb pinchweld seals combine sealing performance with edge protection in one profile. The side mounted foam rubber bulb creates compression against doors, lids and panels while the reinforced gripping section fits securely onto exposed edges.
Unlike standard plain edge trim, these profiles provide both edge protection and environmental sealing. As a result, many automotive and industrial companies use them where protection against dust, water and vibration is important.
Applications of Side Bulb Pinchweld Seals
These profiles are commonly used in:
- Automotive body panels
- Commercial vehicles
- Truck bodies
- Canopies and trailers
- Industrial fabrication
- Electrical enclosures
- Agricultural equipment
- Marine applications
- Compartment and access doors
These sealing profiles are especially useful in applications where sealing performance and edge protection are both required.
