Water- and Steam-Resistant Plastic Washers
Low moisture absorption and good heat resistance make these washers suitable for wet and harsh environments. All are good electrical insulators.
Fiberglass washers are stronger than Delrin® acetal plastic washers and have excellent resistance to salt water. Color ranges from light green to light tan.

Adhesive Lock Washers
When a metal fastener is tightened onto the washer, the embedded epoxy activates and bonds the underside of the fastener head to the mating surface to prevent loosening. The adhesive fills gaps and spaces that other washers fail to seal. Made from fiberglass, these washers have excellent resistance to salt water.
