Title: O-ring insertion tool

Abstract: An O-ring insertion tool for installing O-rings, packings, or seals of various flexible materials into female seal grooves; especially those grooves remotely located, may include a syringe configuration consisting of a barrel and disc-like mandrel that forms an annular opening through which such a seal as forementioned may be ejected at a specifically desired location, and a plunger from which the ejection method is initiated and controlled. With such an arrangement O-rings and other seals of various flexible materials can be easily installed into deeply located female grooves hidden within complicated mechanical parts or assemblies of such.
