Hydraulic cylinders rely on multiple sealing elements working together to convert hydraulic pressure into controlled mechanical movement. Among these components, rod seals and piston seals are two of the most important sealing solutions, each performing a different function within the hydraulic system.   Although both are designed to control fluid leakage, their installation location, sealing...

Seals are vital for stable hydraulic system operation. Wrong material selection causes leakage and premature aging, leading to costly downtime. Nitrile Butadiene Rubber (NBR), Fluoroelastomer (FKM) and Polyurethane (PU) are the most common hydraulic sealing materials, with distinct performance in temperature, pressure and fluid compatibility.   NBR (Nitrile Butadiene Rubber) NBR is a cost-eff...
