It is essential you know certain things before getting seal for whatever unit you are working on. You will need to know the pressure range, temperature range, maximum diametrical clearance and seal width. The main reason a seal wears out is the clearance gap. They can be pinched or cut into, if not seated properly. …
Of course we all know when the hydraulics in the cylinders start to go out, makes our jobs alot harder. It is inevitable the seals will go out from everyday wear and tear, age and seals thinning out. Just don’t use it til you have erosion going on, will cost you more in the long …
