Prime-Line #8 x 1/2 in. O.D. Galvanized Steel Bonded Sealing Washers (25-Pack)

Designed to provide a stronger seal than metal or rubber washers alone, these 1-piece washers are metal for strength laying atop a bonded rubber seal that creates a secure grip. Made of neoprene rubber, the seal produces good oil and abrasion resistance. Washers are reusable. Bonded sealing washers also provide more corrosion protection compared to standard washers.
