Makita Genuine 213643-1 O Ring for Makita AN501H Nailers

The Makita 213643-1 is a genuine OEM replacement O ring designed to restore a reliable air seal in Makita AN501H and AN510H pneumatic nailers.

Manufactured from a durable black elastomer, this O ring seats precisely within the nailer to prevent air leaks and maintain consistent operating pressure. A stable seal is essential for reliable nail driving — even minor pressure loss can affect firing consistency and reduce tool efficiency on site.

Sourcing a genuine Makita part ensures correct material specification and dimensional accuracy, which matters when a nailer is subject to repeated cycling and continuous exposure to lubricated compressed air. Aftermarket seals may not offer the same fit or long-term resistance to deformation.

This O ring is equally suited to planned preventative maintenance and reactive repairs, helping tradespeople and contractors minimise downtime and keep pneumatic equipment performing as intended.
