Making a Tight Seal

Working in multiple mechanical setting for a number of years, one of the first lessons you learn and must always follow is never connect two items without a gasket or seal. There are a number of different gaskets and seals for all shapes and sizes. These ensure a tight seal and prevent future leaks, breaks, blow-outs or other hazards. A common type of asket for a round or “o” shaped object is an o-ring. There are several companies that are o-ring manufacturers. O-rings are versatile and can be used in a variety of applications, large or small. They can also be made to withstand temperature extremes, both hot and cold.

O-rings are a simple perfectly round design that can be made out of a number of different materials, which depend on the composition of the items that the gasket is buffering. Some materials that o-ring manufacturers typically use are: polyurethane, neoprene, silicone, fluorocarbon and nitrile rubber. It is imperative that the o-rings fit well and hold their seal in order to perform their function. That function could be keeping a tight seal for a combustion engine cylinder, to a vacuum hose or even pipes that hold the water inside of your home.

Depending on the location of the o-ring, it may need to be lubricated before being inserted into its resting place. If the joint is motionless the o-ring usually does not need to be lubricated. However, it the joint is moveable it most likely will have to be. This will extend the lifetime of the ring and slow deterioration. They are an easy to manufacture and relatively cheap to produce. Although inexpensive and easy to produce the importance of them is priceless. Some accounts have said that the 1986 Challenger catastrophe was a failure because of an o-ring that did no seal properly.
