Introduction

This guide will help you replace a leaky O-Ring caused by exposure to the elements or damage during disassembly. All you will need to access this are iFixit opening picks. It is recommended that this is replaced anytime the device is opened as it can be pinched or torn during removal of the face plate or device housing.
