Top Bulb Rubber Seal

Looking for a reliable top bulb rubber seal in South Africa? Our Rubber Profiles range includes practical sealing solutions for lids, hatches, doors and access panels. This profile grips firmly onto an exposed edge and uses a soft top bulb to create a seal when the closing surface presses down onto 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.

Bulb Rubber Seal Applications

Choose a top bulb rubber seal when the closing surface presses down from above instead of against the side of the profile. Therefore, this type of seal works especially well on boots, lids, hatches and top-closing panels. Many customers also use this profile as a universal boot seal on vehicles, trailers, canopies and outdoor compartments. Because the top bulb compresses during closing, the profile helps create a reliable seal against water, dust and noise.

• vehicle boot openings
• trailer lids and storage compartments
• canopy doors and hatches
• camper and caravan access panels
• marine lids and hatch openings
• toolboxes and storage boxes
• machine covers and industrial enclosures
• outdoor equipment compartments

If you need a profile that compresses from the side, our Side Bulb Rubber Seal range may be a better fit. However, if you only need edge protection without compression sealing, you can also view our Rubber Edge Trim range.
