402 Series Double Bulb Seal

Product Details

About This Lid Seal

Rubber double-bulb seals consist of two flexible bulb-shaped profiles made of durable EPDM and sponge rubber materials. Our double bulb lid seal with EPDM sponge rubber has a height of .500" and a width of 1.500". Find out which adhesive to use with your EPDM bulb seal below so you can choose BT or HT when ordering.

Double-Lip Seal Applications

Our extruded double-bulb lid seals, gaskets, and weatherstrips are used in conjunction with each other to protect cargo and other areas of your vehicle or boat from:

  • Humidity
  • Water 
  • Outdoor elements

When a truck cap or similar truck cover, these bulbs compress against the frame, creating a tight seal. This dual-seal design enhances insulation, minimizing air and moisture infiltration, thus improving energy efficiency and preventing drafts.

3M™ BONDED TAPE SYSTEM 

The 3M Bonded Tape System enables you to achieve the ultimate bond to the rubber and the ultimate bond to the substrate. This tape option creates a moisture barrier and air-tight seal. With the highest peel-and-sheer resistance, the 3M Bonded Tape System can be used under high loads of stress and force. It has low initial tack for easy repositioning during installation and needs 72 hours of cure time to come to full-bond strength. It is rated for good heat performance between -20°F to 158°F.

3M™ Heat-Activated Acrylic Foam and Acrylic Plus Tape Application Guidelines

STANDARD PRESSURE SENSITIVE ADHESIVE

The Standard Pressure-Sensitive Adhesive option for your seal is an acrylic-based adhesive. It works best when used to hold the seal in place while installing in a static application or when it’s compressed between two stationary objects. It may be used in some light-duty dynamic applications against a variety of substrates. It is rated for good heat performance between -20°F to 158°F. Please note: During installation, the ambient temperature must be above 60°F.
