Importance of O Ring Lubrication

o ring lubrication

Why is O Ring lubrication important? Why lubricate? All kinds of lubrication, including oils, greases, water and air are used to reduce wear by minimising heating and friction of moving elements. Any substance that accomplishes this, can be called a lubricant. Types of lubricants Lubricants help reduce friction in the application. These lubricants can be: Semi-Permanent Lubricant Coatings There are […]
