5/8 Inch Dowty Washer for Hydraulic Connections SKU: QT1528

A failing seal in hydraulic connections means more than just fluid leaks—it creates pressure loss that robs your hydraulic system of power and responsiveness when operating loaders, three-point implements, or remote hydraulics. This 5/8 inch dowty washer provides the bonded rubber-to-metal seal that prevents hydraulic fluid loss and air contamination in high-pressure applications.

Why This Seal Design Works

• Bonded rubber gasket creates positive seal under hydraulic pressure
• Steel washer backing prevents deformation during bolt tightening
• Designed for repeated assembly cycles without seal degradation
• Resistant to hydraulic fluid breakdown and temperature extremes

Hydraulic systems depend on tight connections to maintain proper pressure and flow. These dowty washers eliminate the guesswork in achieving leak-free hydraulic fittings, whether you're servicing pump connections, valve bodies, or hydraulic cylinder assemblies. S&H Parts has been supplying reliable hydraulic components since 1969—call if you need help identifying the right seal for your application.
