8800-18 Bonded Seal (Buna-N) for Metric Parallel Thread

Product Overview

The 8800-18 Bonded Seal (Buna-N) for Metric Parallel Thread is a precision-engineered sealing washer designed for metric parallel thread hydraulic port connections.

It features a carbon steel outer ring bonded with a Buna-N (NBR) elastomer sealing element, providing a strong, pressure-tight seal between the fitting and the port surface. This design is essential in applications where threaded connections alone cannot ensure leak-free performance.

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