Overview

Support reliable maintenance with Honda Genuine OEM Automatic Transmission Drain Plug Washers. This 5-pack uses a precise 18mm sizing and is designed for single-use during fluid changes, helping to restore the intended seal after draining and refilling. The washers are built to match Honda’s factory specifications, offering a confident, straightforward replacement when servicing transmission drains and rear differentials.

What’s included and sizing

The kit provides five washers that align with Honda automatic transmission drain plugs and the rear differential drains used on popular models such as the Pilot and Ridgeline. The 18mm dimension ensures a consistent, even crush for a proper seal during service.

  • Factory-grade replacement washers, sold as a five-pack
  • 18mm size fits Honda automatic transmission drain plugs
  • Compatible with Pilot and Ridgeline rear differential drains

Why use OEM washers

Choosing genuine Honda components helps maintain compatibility with factory fit and material quality. Using authentic washers supports expected seating and seal behavior during maintenance and reduces the risk of using non-OEM parts.

How to use

During a routine fluid service, replace the old washer with a fresh 18mm Honda drain plug washer. Replace the washer whenever you drain and refill fluids, and dispose of the used washer properly.

  • Use one new washer per plug during transmission or differential service
  • Do not reuse old washers to maintain sealing integrity
  • Follow the vehicle’s service manual for torque recommendations and procedures

Real-world benefits

While results vary by vehicle and service conditions, these factory washers are designed to align with OEM specifications, offering consistent seating and a clean seal during routine maintenance.
