This Dowty Petcock Sealing Washer Set is as the original and will fit Triumph and Norton petcocks as well as BSA models that have been retrofitted with Triumph petcocks. The kit includes 4 flat washers and 4 bonded rubber washers.

Key Features of Dowty Petcock Sealing Washers Set:

• Bonded Seal Design: Dowty washers, also known as bonded washers, feature a seal that is bonded to the metal washer. This design provides a reliable and effective seal, preventing leaks in static applications such as fuel systems.
  
• Material Composition: The combination of a metal washer and an elastomer seal enhances the durability and sealing capability. The metal component provides structural integrity, while the elastomer element ensures a tight seal by compensating for surface irregularities.
  
• Versatility: Dowty washers are used in various applications, including automotive and industrial settings, due to their ability to provide effective sealing under high-pressure conditions. This versatility makes them suitable for classic motorcycles like Triumph and Norton, where reliable sealing is crucial
