Honda OEM Drain Plug Washer 94109-14000 – 14 mm

The Honda OEM drain plug washer 94109-14000 is the original sealing washer used on the oil pan drain bolt in most Honda engines. Made to factory specifications, it ensures a proper seal between the drain bolt and the oil pan during every oil change.

This washer fits a 14 mm drain bolt and is also used on the drain plugs of some Honda manual transmissions. Because the washer deforms slightly during tightening, it should be replaced at every oil or gearbox fluid change to ensure reliable sealing and prevent leaks.

Why use the original Honda washer?

• perfect fitment – correct diameter, thickness and material composition,
• reliable sealing – prevents oil seepage and protects the oil pan threads,
• stable installation – no need to overtighten the drain plug,
• compatible with many Honda engines – widely used across multiple generations,
• also fits some manual transmission drain plugs where a 14 mm washer is required.

Important note about packaging

Honda supplies the 94109-14000 washers in bulk packaging (e.g., a factory bag of 50 pieces, visible in one of the photos). For this reason, individual washers are sold without individual OEM packaging. The product is 100% original and sourced directly from official Honda distribution.
