2x Replacement O-Ring Seals for 4iiii Precision 2 Power Meter Battery Cap Non Drive Side.

If your O ring seal has split then simply replace it with this seal. This seal is made of a different and more robust rubber material better suited to a friction O ring cap application. The original white O ring seals are very soft and easily wear or break allowing water ingress which damages the power meter or creating a loose fit for the cap which is then lost. This O ring provides a better/tighter seal and is more resistant to wear/abrasion.  Note: It does not include the Battery Cap itself.

This listing is for 2 O rings. If you want just 1 O ring then see my other ebay listing (there is a 10% discount included in this listing price for buying 2 O rings). This is a multi item listing, so if you need multiples of 2 O-rings, then simply change the quantity required at the top of the listing before buying.  

Note - This is the Non drive side O ring. The O ring for the drive side crank arm battery cap is a different size and you can buy this on another of my listings
