They can be used to solve difficult application problems involving hightemperatures, as well as acidic, corrosive and wash-down environments. Because oftheir long life and self-lubricating qualities, they are especially suitable for installationsthat cannot be accessed easily, or where performing regular maintenance is difficult.• Sizes - 1 ½ to 6"
