DUCTILE IRON PISTON/GLA..

DUCTILE IRON PISTON/GLAND COMPARED TO STEEL PISTON/GLAND

Ductile iron piston/gland is outdated technology. Ductile iron was originally an appealing material for cylinders because of its strength and high concentration of carbon. However, these same positive traits are also its weakness, because the hardness of the iron causes greater wear on the rod and the honed tube of the cylinder.
Cylinder manufacturers that use iron pistons do not have any seals and only have one rubber o-ring, causing the rest of piston to create friction against the tube. Magister Hydraulics’ steel pistons have high quality polyurethane seals that greatly reduce friction inside the tube and prolongs the life of the cylinder.
Cylinders with standard ductile iron piston/glands have an average lifespan of 3 years, whereas Magister Hydraulics’ cylinders manufactured using steel piston/gland combined with polyurethane seals prove to have an average lifespan up to 7 years.
