8800-27 Bonded Seal (Buna-N) for Metric Parallel Thread

Product Overview

The 8800-27 Bonded Seal (Buna-N) for Metric Parallel Thread is a precision sealing washer designed for metric parallel thread hydraulic port connections.

It combines a carbon steel outer ring with a Buna-N (NBR) elastomer sealing element, creating a durable, pressure-resistant sealing solution between a threaded fitting and its mating port surface. This design is essential where threaded engagement alone cannot provide a reliable leak-free seal.

It is widely used in hydraulic systems, industrial machinery, and OEM applications requiring dependable static sealing under pressure.
