The 8800X18 Bonded Sealing Washer (18 mm) is a reliable sealing solution for metric parallel thread connections, designed to prevent leaks in hydraulic and fluid transfer systems. This bonded seal combines a carbon steel outer washer with a rubber sealing insert, creating a tight, dependable seal when compressed between mating surfaces. Built for M18-1.5 metric threads and 18 mm tube OD applications, it’s a small component that does a very big job—because when fluid systems start leaking, they rarely do it politely.
