Rubber Seals create an easy-to-close seal against dust, noise, and vibration. To prepare, cut to length with scissors or knife. Prior to installation, ensure bonding surface is properly cleaned with a 50/50 mix of denatured alcohol and water solution. The Solid Rectangle Rubber Seals are available with two adhesive application options: high-strength foam acrylic adhesive (BT) and general-purpose pressure sensitive adhesive (HT). The (BT) adhesive creates an airtight seal between the rubber and substrate and has low initial tack for easy repositioning. Square foam rubber is flexible and easily cut to match the equipment, it has dust resistance to prolong service life of equipment.
