Description & Features

Designed for use in hydraulic and fluid power assemblies, this 52mm x 2.0 bonded seal provides a reliable face seal between a bolt head and a machined port surface. The bonded seal construction combines a metal washer with a vulcanized elastomeric sealing element, allowing it to compress and form a leak-resistant seal when torqued into position. This design is well suited to applications where a secure, reusable seal is needed at threaded port connections.

Supplied by Adaptall under part number 9500-52MM, this seal is sized for 52mm applications with a 2.0 profile designation. Adaptall is a recognized manufacturer of hydraulic adapters and sealing components, and this bonded seal is consistent with their standard product line for metric port sealing.

Question by: Tammy G on Jan 6, 2026, 9:18 PM
what exactly is a bonded seal and how's it different from just using a regular washer at a port connection?
Answer by: Customer Support on Jan 8, 2026, 6:17 PM
A bonded seal combines a metal washer with a rubber sealing element that's vulcanized directly onto it. When you torque it down, that elastomeric ring compresses against the machined port surface and forms a leak-resistant face seal. A plain washer doesn't have that sealing element, so it won't close off fluid paths the same way. The bonded construction is what makes it work as both a fastening and sealing component at the same time.

got a 52mm metric port, is this the kind of seal that goes under the bolt head to keep it from weeping?
Answer by: Customer Support on Sep 19, 2025, 6:40 AM
For a 52mm setup, this bonded seal is meant to sit between the bolt head and the machined port face. When you torque the bolt down, the metal washer supports the seal and the vulcanized elastomer compresses to make a leak-resistant face seal.
