About Washers
More
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.
Delrin® acetal plastic washers combine a slippery, wear-resistant surface with good strength and rigidity.
