K12 is a single acting scrapper ensuring that foreign particles are not introduced into the hydraulic cylinders , avoiding wear and damage to all the internal components including seals.

PRODUCT ADVANTAGES
• Superior scraping effect
• Simple , easy-construction groove
• No twisting in the housing
• Design in a way that the wiping lip contacts with the rod surface to remove heavily deposited mud , ice , etc so that the particles do not enter into the cylinder
• Outside diameter contacts the housing and has a sealing lip to prevent moisture entering the groove.

APPLICATION
Especially used in heavy construction machinery that operate in the open field , telescopic cylinders , cranes , mining equipment and loading platforms.
