Side Bulb Rubber Seal

Looking for a reliable side bulb rubber seal in South Africa? Our Rubber Profiles range includes practical sealing solutions for doors, lids, hatches and access panels. This profile grips securely onto an exposed edge and uses a soft side bulb to create a tighter seal when a panel closes against it. As a result, it helps reduce water, dust, draughts and noise ingress. In addition, the profile gives the edge a cleaner and more finished appearance.

Side Bulb Rubber Seal Applications

Choose a side bulb rubber seal when the closing surface presses against the side of the profile rather than from above. Therefore, this type of seal works well on vehicle doors, trailer compartments, canopies, machinery covers and industrial enclosures. Many customers also use certain profiles in this range as a door seal with lip or as a sealing solution for transport and outdoor equipment. Because the bulb compresses on contact, the profile helps create a tighter and more reliable seal.

• vehicle doors and door frames
• trailer compartments and side doors
• canopies and storage compartments
• camper and caravan doors
• toolboxes and access covers
• machine guards and industrial enclosures
• electrical cabinets and inspection panels
• marine and outdoor hatch applications

If you only need edge protection without compression sealing, our Rubber Edge Trim range may be more suitable. However, if the closing surface presses down from above, you may prefer our Top Bulb Rubber Seal range.

A side bulb rubber seal seals gaps around doors, lids, hatches and access panels. It grips onto the panel edge and compresses when the closing surface presses against the side bulb.
