O-ring lubrication is essential for installing o-ring seals of all kinds. The highest benefit of using o-ring lubricant is obtained during o-ring installation. Using an oil or a grease while assembling will help protect an o-ring from damage by cutting, pinching, or abrasion. O-ring lubrication helps install the o-ring with accuracy and speeds up assembly operations. Order o-ring lubricant, o-rings, and other water filter parts from Serv-A-Pure today!
