Product Details

The Honda OEM Clutch Master Cylinder Seal Ring is a genuine factory replacement designed to provide a secure, leak-resistant seal at the clutch master cylinder hydraulic connection on compatible Honda and Acura vehicles equipped with manual transmissions.

This small but essential sealing component helps maintain proper hydraulic pressure within the clutch system, allowing consistent clutch pedal operation and smooth gear changes.

Over time, the original seal ring can deteriorate, flatten, harden, or become damaged during clutch master cylinder replacement or hydraulic line servicing. A worn or damaged seal may allow hydraulic fluid to leak, potentially causing reduced clutch pressure, inconsistent engagement, or difficulty shifting gears.

Manufactured to Honda's original equipment specifications, this genuine seal ring provides reliable sealing performance and factory-quality fitment. It is an excellent replacement when servicing the clutch master cylinder, replacing hydraulic fittings, or installing compatible aftermarket clutch hydraulic components.

Features
  • Genuine Honda OEM Part: Manufactured to Honda's original factory specifications.
  • Clutch Master Cylinder Seal: Designed to seal the hydraulic connection on compatible clutch master cylinders.
  • Leak-Resistant Design: Helps prevent hydraulic fluid from escaping the connection.
  • Maintains Hydraulic Pressure: Supports consistent clutch pedal operation and proper clutch disengagement.
  • Factory Replacement: Matches the original Honda sealing component.
  • Ideal for Clutch Repairs: Recommended when disconnecting or replacing clutch master cylinder hydraulic fittings.
  • Aftermarket Compatibility: Also used with certain K-Tuned clutch master cylinder upgrade kits and -3AN hydraulic fittings.
  • OEM Part Number: 46943-S5A-003.

Installation Notes
  • Before installation, inspect the clutch master cylinder hydraulic fitting and connection surfaces for damage, corrosion, or debris.
  • Remove the original seal ring and clean the sealing area. Install the replacement Honda OEM seal ring in the correct position, ensuring it is not twisted, pinched, or damaged.
  • Reconnect the hydraulic fitting and secure it using the appropriate factory retaining hardware.
  • If the hydraulic system has been opened, refill the clutch fluid reservoir with the Honda-specified fluid and thoroughly bleed the system to remove trapped air.
  • After installation, inspect the connection for hydraulic fluid leaks and verify proper clutch pedal operation before driving.
