K43 is a three piece single acting sealing set which consists of onereinforced cotton fabric and nitrile rubber vulcanized together , one L shaped thermoplastic guide back-up ring and a retainingring.

PRODUCT ADVANTAGES
• Functions even with poor surfaces
• Limited space due to the open housing in one-piece piston
• Reinforced cotton fabric base prevents the seal from extrusion
• Good sealing at low pressures

APPLICATION
Mining equipment , after market , mobile hydraulics , presses andstandard cylinders.

Groove Base Ød ≤1.8 μm ≤6.3 μm
Groove Flanks B ≤3.2 μm ≤16 μm
Note: It is recommended to have 50% to 90% of the working surface material contact area value.

INSTALLATION
Easily assembled into one-piece piston by hand. Open groove design gives an advantage for easy machining and reducing the machining costs. 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.
