KASTAS ROD SEALS K37
K37 is a two piece single acting rod seal which consists of a reinforced cotton fabric and nitrile rubber vulcanized together forming an integral sealing element and one thermoplastic back-up ring.
PRODUCT ADVANTAGES
• Functions well even with poor surfaces
• Reinforced cotton fabric base prevents the seal from extrusion
• Good sealing effect at low pressures
• Improved sealing gap due to the active back-up ring
APPUCATION
Mining equipment, after market, mobile hydraulics, presses and
standard cylinders.

INSTALLATION
K37 is to be assembled into open grooves. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.
