When installing O-rings, a suitable lubricant should be used to reduce friction and prevent damage. A tool called an O-ring installation tool can also be used to ensure proper placement and avoid twisting or pinching the O-ring. This information is found on the Global O-Ring and Seal website (https://www.globaloring.com/o-ring-in...) under the sections "Lubrication" and "Tools." Moreover, the surface where the O-ring will be installed must be clean and free from sharp edges, burrs, or spiral machined finishes to prevent damage. This information is found on the Parker Hannifin O-Ring Handbook (https://www.parker.com/literature/O-R...) on page 6-3 under the section "Surface Finish and Hardness." See full answer »
