Honda Civic/Integra/Prelude Clutch Master Seal 46928-SF1-000

Honda Clutch Master Cylinder Seal, Civic, Integra, Del Sol, Prelude, Accord

This is the Honda Civic clutch seal, 46928-SF1-000, you replace when the rubber at the firewall gets hard, cracked, or starts letting the engine bay into the cabin. It sits between the clutch master cylinder and the firewall, so it works as both a Honda clutch firewall seal and a locator that keeps the master sitting flat. When it fails, you can get extra vibration, squeaks, a little stink of fumes, or moisture and grime sneaking past the pedal area. It is one of those small parts that makes the car feel cheap when it is bad, and normal again when it is fresh.

You pull the master or at least loosen it, swap the rubber, and tighten everything back down so the cylinder clamps evenly. We use these exact seals on our own cars because a clean firewall and a solid master mount beats chasing random pedal noise later. If you want factory style fitment without guessing on thickness, this is the straightforward fix for Acura clutch cylinder sealing and the usual Honda and Acura clutch master setups.
