About This D-Shaped Weather Stripping

This D-shaped sponge rubber seal, measuring .375" (w) by .250" (h), creates a moisture barrier, as well as a water-tight and air-tight seal between your substrate and the rubber. It seals out air leaks, moisture, dirt and debris. D-shaped weather stripping also reduces vibration and helps to cancel some noise.

You can use these D-shaped EPDM sponge rubber seals between a variety of two substrates that have even or uneven gaps, such as:

• Doors (house, garage, auto, RV
• Car trunks
• Windows
• Hatches
• Electrical enclosures
• Coolers
• Lids
• And more

When you’re choosing between D-shaped sponge rubber seal sizes, choose the one that will provide 25-40% compression for your application. This will give you optimal seal performance, especially at 25% compression. Review the specs, adhesive, installation details, and more for this EPDM D-shaped rubber seal below.
