Introduction
O-Rings are prone to wearing out due to generally wear and tear during operation and worsened by a lack of lubrication or improper oil. O-rings maintain proper seals through out the nail gun and leaks make the gun prone to misfires, jams, and lack of power needed for the fasteners to reach proper depth. O-Rings are disposable once they have deteriorated to the point of effecting the nail guns operation and will need to replaced with new O-rings.
