High-Quality Ashton Bonded Seals for Industrial Applications
Ashton bonded seals are reliable, cost-effective sealing washers designed for general industrial, hydraulic and fluid sealing applications. Manufactured to consistent quality standards, these seals provide a dependable leak-proof solution for bolts, screws and threaded connections. Produced using trusted global manufacturing partners, Ashton bonded seals offer a practical alternative to premium brands while maintaining strong performance across a wide range of applications.
What Are Ashton Bonded Seals?
Ashton bonded seals are metal washers with a bonded elastomer sealing element, designed to prevent leakage under compression.
They consist of:
- A metal outer ring for structural strength
- A rubber inner sealing element for leak prevention
- When installed, the elastomer compresses to form a tight seal between mating surfaces, making them ideal for hydraulic, pneumatic and fluid systems.

FAQs About Ashton Bonded Seals
1. What are Ashton bonded seals used for?
They are used to create a leak-proof seal around bolts and threaded connections in hydraulic, pneumatic and fluid systems.
2. Are Ashton bonded seals suitable for hydraulic applications?
Yes, they are commonly used in hydraulic systems where reliable sealing is required under pressure.
3. What materials are Ashton bonded seals made from?
They are made from a metal outer ring (such as steel or stainless steel) with a bonded rubber inner seal (e.g. nitrile, Viton or EPDM).
4. How do bonded seals work?
When compressed, the rubber inner ring deforms to fill gaps between surfaces, creating a tight seal that prevents fluid leakage.
5. Are Ashton bonded seals reusable?
They can be reused if undamaged, but for critical applications it is recommended to replace them to ensure optimal sealing performance.
6. What industries use bonded seals?
They are widely used in hydraulic systems, automotive engineering, industrial machinery and general maintenance applications.
