Self-Sealing Washers

Self-Sealing Washers

Panova provides a product line of Self-Sealing Washers and Self-Sealing Lock Washers engineered to provide long-term reliability in a wide range of rubber seal applications. Our Self-Sealing Washers are conveniently designed to use in combination with standard screws and bolts to seal out water, oil, dust, solvents, and other intrusive materials or contaminants.

• Our one-piece molded Self-Sealing Washers are designed with offset sealing elements that allow the seal to fit with standard, oversize, and eccentric holes.
• Our standard washers are made from stainless steel, bonded with a sealing element that is made from either silicone or Buna-N rubber.
• Our symmetrical Self-Sealing Washers feature identical designs on both sides. This allows for a simpler, more streamlined installation process and facilitates automated assembly solutions.

Self-Sealing Washer Features and Benefits

Manufactured from premium quality rubber materials, Panova’s custom self-sealing washers provide reliable sealing for screws and fasteners. Upon installation, the screw head seals, stopping the ingress of water, oil, and dust to protect internal components and/or prevent corrosion. Additionally, our self-sealing washers feature carefully-engineered elastomer properties which provide ideal screw tension once compressed.

• Metal-to-metal contact provides torque control and a premium finished appearance.
• Sealing element is not exposed to external damage, improving long-term reliability.
• Designed to work with vacuum sealing as well as high-pressure liquids or gasses.
• Reliable rubber seals which completely prevent leakage or intrusion of liquids, gasses, solids, and dust.
• Engineered to conveniently work with standard screws and bolts.

Self-Sealing Lock Washers

Panova’s Self-Sealing Lock Washers are economical washers that are ingeniously designed to provide sealing and locking simultaneously.

Molded within each of our Self-Sealing Lock Washers is a high-quality lock washer with internal teeth that is encapsulated in rubber. Internal tooth-lock washers have teeth located along the inside diameter to provide a good connection with fastener heads and the mating surface. This connection prevents fasteners from turning, slipping or loosening due to vibration or torque.

Our standard Self-Sealing Lock Washers are available in quality stainless steel or zinc steel. The standard sealing materials used are silicone or Buna-N rubber.
