3. Protection Against Contaminants Hydraulic systems are often exposed to dust, dirt, and other contaminants that can compromise performance. Oil seals act as barriers, preventing these harmful particles from entering the hydraulic system and causing wear or damage to the internal components.

An oil seal, often referred to as a fluid seal, is a device that seals the interface between two components, preventing the leakage of oils or lubricants. Oil seals are typically made from elastomeric materials that provide flexibility, resilience, and resistance to wear and tear. They are essential for ensuring the proper functioning of machinery by minimizing contamination from external elements and retaining lubricants within the system.

The design of high-pressure rotary shaft seals typically includes a flexible sealing lip that makes contact with the rotating shaft, combined with a robust outer component that holds the seal in position. The materials used in these seals must be durable and resistant to wear, heat, and chemicals. Common materials include elastomers like nitrile rubber, fluorocarbon rubber, and special composites designed for high-performance situations.

The process of extrusion in aluminum usually involves the passage of a solid aluminum billet into a die. This is typically done with the assistance of a high-pressure hydraulic press, or ram, to force the block into the die. 

Even little items like the screws and bolts used can be something that makes installation a pain or detracts from the look of the fence.  Make sure the hardware is color matched to your pieces and uses a stronger hex-head on the bolts that allow use of a socket.  Phillips head style screws can often strip easily and make installation a pain.
