  • Moisture
  • Dirt and debris

These half-round sponge rubber seals also provide vibration reduction and some noise cancellation. They’re recommended for use between two substrates such as:

  • Doors (house, garage, auto, RV, etc.)
  • Car trunks

  • Hatches
  • Electrical enclosures
  • Coolers
  • And more

Half-Round Rubber Seal Industries

When used as a self-adhesive door seal, D-shaped EPDM sponge rubber seals can fill in gaps on doors and lids where the gap may vary in size. They are also chosen by OEMs for a variety of industries, such as manufacturing, automotive, and more. For optimal performance, remember to choose the D-shaped weatherstripping rubber seal in a size that will provide 25–-40% compression for your application.

The BT option for your self-adhesive rubber seal provides the ultimate bond to the rubber and the ultimate bond to the substrate. It creates a moisture barrier and air-tight seal. With the highest peel and shear resistance, it can be used under high loads of stress and force. It has low initial tack for easy re-positioning 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.

The HT option for your D-shaped EPDM sponge rubber seal is an acrylic-based adhesive. It works best when used to hold the rubber seal in place while installing in a static application or 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.
