FAQ

What are the recommended operating conditions for the Kastas K52 seal?

The standard K52 with an NBR ring typically operates at pressures up to 300 bar, temperatures from -30 deg C to +105 deg C, and speeds up to 0.5 m/s. It is compatible with mineral oil based hydraulic fluids (HL, HLP).

Is this the complete K52 seal set or just the NBR profile ring?

This listing is for the main NBR profile ring as shown in the images. The complete K52 set also includes two thermoplastic support rings and two POM guide rings, which are not included here.

What are the critical installation steps to prevent damage to this type of piston seal?

Ensure the housing and piston surfaces are free of sharp edges and burrs. Use an appropriate lubricant and a correctly sized installation tool. The seal should be carefully guided into the groove without twisting or folding to avoid premature failure.
