k504

K504 is a three piece double acting compact seal which consists of one fabrik reinforced elastomeric sealing element and two thermoplastic guide back-up rings.

PRODUCT ADVANTAGES
• Low friction , free of stick-slip
• Improved abrasion resistance
• Good dynamic and static sealing
• Long service life
• Reliable solution in water and water based media

APPLICATION
Mining equipment , iron and steel industry , marine hydraulics and earth moving equipment.

INSTALLATION
K504 profile has been designed to be installed in a closed or open grooves taking the indicated catalogue information into consideration. We recommend having open groove design for dimensions that are smaller than Ø 50mm. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.
