Specification

Center Joint Seal Kit Describe

Standard seal: Unless otherwise specified on your unit, you most likely need to purchase a standard seal kit. Standard seals are usually made of nitrile and are intended to be used in air and mineral-based hydraulic oils.
Loaded lip seal: Loaded lip seal configurations are ideal for low-pressure applications in a variety of industries including construction, automation and manufacturing. While loaded lip seal designs are generally extremely durable, they occasionally need to be replaced.
Fluorocarbon seals: Combining high-temperature resistance with superior chemical resistance, Fluorocarbon seals are ideal for high-pressure applications. Because these seals are often utilized regularly, they tend to break down over time. Yates Cylinders sells seals in a variety of sizes and price points.
Cast iron piston rings: These rings are used in a variety of high-speed and high-temperature applications including automation and construction. Cast iron piston rings are highly durable and are often used for heave shock applications because of their strength. Keep in mind these rings do not create the complete seal that urethane or rubber seals do. However, they can withstand much higher shocks and are wider and deeper than the standard ring configuration.
Low-friction seals: Operators of systems powered by fluid frequently need friction-optimized seals for hydraulic cylinders. Having too much friction wastes energy and can cause the seal to fail prematurely. However, having too little friction can cause leaks. Our low-friction seals are specially calibrated to create the right amount of friction for a variety of applications.

Features

O ring kit are suitable for use on a variety of mechanical equipment, in the prescribed temperature, pressure, and different liquid and gas media in a static or moving state to seal. In Machine tools, ships, automobiles, aerospace equipment, metallurgy machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, as well as various types of instrumentation, a large number of applications of various kinds of sealing elements. O-ring seals are mainly used for static seals and reciprocating movement seals. For rotary motion seals, it is limited to low-speed rotary seals. O-type seals generally installed in the outer circle or the inner circle of the rectangular groove in the sealing function. O-type seals in the oil, acid and alkali, grinding, chemical erosion and other environments still play a good seal, damping effect. Therefore, O-ring is one of the most widely used seals in hydraulic and pneumatic transmission systems.
