4. FAQ
Q: What material is this piston seal ring made from?
A: It is most commonly made of nitrile rubber (NBR) for general use, or high-performance polyurethane (PU) for heavy-duty hydraulic systems. Some premium versions use fluorocarbon rubber (FKM) for extreme heat and chemical resistance.
Q: What is the main purpose of this piston seal ring?
A: It acts as the primary pressure barrier on the piston, preventing high-pressure hydraulic fluid from bypassing the piston inside the cylinder. This ensures the cylinder maintains its force, holds loads reliably, and operates without drift.
Q: What color is this piston seal ring?
A: It is a solid, deep black. This is typical for these seals, as the color comes from carbon black additives that improve durability, heat resistance, and resistance to aging.
Q: What is the structure of this piston seal ring?
A: It is a thin, continuous circular ring with a precision cross-sectional profile designed to fit into the piston’s groove. The shape is engineered to maintain consistent, low-friction contact with the cylinder wall while withstanding repeated movement.
