K57 is a double acting complete piston seal which consists of an aluminum plate vulcanized with elastomeric nitrile rubber using special production methods.
PRODUCT ADVANTAGES
• Ready to fit complete piston
• Reliable pressure application at the end of stroke by the
venting passages
• Low friction and smooth running due to sealing lip
geometry
• Easily fastened to the piston rod without using additional
sealing elements
• Economical sealing solution
APPLICATION
Standard pneumatic cylinders and after market.
