Online Intro To Hydraulic Seal

A hydraulic seal is a device that restricts an escape of fluid and any other foreign materials from entering a hydraulic device or application. A cylinder is an example of a hydraulic device. All hydraulic seals are designed to managed high pressure and dynamic applications, such as in the case of hydraulic cylinders. For all kinds of industrial use machinery, hydraulic seals remain one of the most important components. Customized seals continue to be designed, manufactured and prepared for those industrialists dealing with unique manufacturing and/or processing situations.

Customized seals can be applied to support rotary and reciprocating movements. Typical seals being manufactured for industry situations around the country, and across the world, include back up rings, O rings, rod seals, piston seals, rotary shaft seals, symmetrical seals, wipers, static seals and wear rings. Buffer rings, U cups, oil and grease seals and gaskets are also being prepared. Piston rings are manufactured from cast iron. Hydraulic seals are designed to be double acting or single acting. Single acting seals will only be utilized for one (axial) direction.

Double action seals will be prepared for use in both directions in order for the reciprocating motion to be put in motion if you will. Hydraulic seals are built from a variety of materials. These include PTFE. PTFE can be glass filled, nickel filled or bronze filled. Other materials being utilized to build the hydraulic seal include nitrile, polyurethane, fluorocarbon or FPM rubber, silicone and nylon. And then there are those seals that are being molded directly from leather as well as fabric reinforced rubber.

So, it is plain to see that if you are thinking of moving into an industrial space, you will most likely end up utilizing hydraulic seals if you are going to be working with fluids.
