48633-94500 – O-Ring Head Seal – Suzuki

The 48633-94500 Suzuki o-ring is a genuine OEM marine seal used in Suzuki trim cylinders and related engine head assemblies. This sealing ring fits inside the trim head or cylinder housing to create a tight fluid-resistant seal. It helps keep hydraulic fluid or other engine fluids inside the correct chambers and prevents leaks that could lower performance or cause damage. Suzuki designed this o-ring to match strict factory dimensions and material requirements so it performs reliably in harsh marine conditions like saltwater and vibration.

This o-ring is commonly used in trim cylinder head assemblies on various Suzuki outboards. It forms part of the seal set in hydraulic trim systems where the trim piston and cylinder meet. Before installing the 48633-94500 Suzuki o-ring, clean the cylinder bore and piston surfaces thoroughly. Make sure to remove old seal material and inspect the grooves for wear. Then place the o-ring into its groove and coat it lightly with a marine-safe lubricant to ease installation. This prevents pinching or twisting during seating. Proper installation ensures the hydraulic system maintains pressure and the trim piston moves smoothly.

Genuine OEM parts like this o-ring typically hold up better over time and fit more precisely than many aftermarket replacements. Also, because it matches Suzuki’s original engineering, it helps your engine’s trim or hydraulic components operate correctly without fluid loss or slip. Replacing worn seals as part of regular maintenance helps protect your outboard over the long term.
