High-Pressure-Rated Metal-Bonded Sealing Washers
316 Stainless Steel with PVC Plastic Sealant Seal
Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.
316 stainless steel washers have excellent resistance to chemicals and salt water and may be mildly magnetic. They are bonded to a PVC sealant that, when tightened, creates an impervious 360° seal around your fastener’s threads. Washers are not reusable.

Metal-Bonded Sealing Washers
Create a stronger seal than metal or rubber alone. These one-piece washers are metal for strength with a bonded rubber seal that creates a tight grip. Made of neoprene, the seal has good oil and abrasion resistance. Washers are reusable.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic.
