Material integrity is critical when dealing with hydraulic fluids and varying operating temperatures. Our standard GA seals utilize high-grade NBR, which offers excellent compatibility with mineral-based hydraulic oils and provides high resistance to compression set. For environments involving high-temperature spikes or aggressive chemical agents, we also offer FKM options, which retain structural elasticity and chemical resistance at temperatures exceeding 200°C. Careful selection between these elastomers ensures that the seal remains pliable rather than brittle, preventing the seal extrusion that typically leads to catastrophic hydraulic failure.

Proper installation is paramount to achieving the seal’s rated service life. The GA seal should be installed with the lip facing the pressure side to ensure it self-energizes correctly. During maintenance, avoid using sharp tools that could scratch the rubber lip, as even minute surface imperfections can lead to fluid bypass. Because the CFKS GA seal is designed for low-friction operation, it does not require significant pre-lubrication, though applying a thin film of clean system oil is recommended. Regular inspection of the rod surface for pitting or scoring is advised, as a damaged rod will accelerate wear on even the highest-quality elastomer.
