Kluber Barrierta L 25 DL is a special lubricating grease for lubricating sensitive plastics and elastomers. Engineered with perfluorinated polyether oil and PTFE this helps the resistance to water or hydrocarbons. Barrierta L 25 DL is designed to provide reliable, low-friction lubrication for sensitive friction points and demanding environments.

Barrierta L25 DL is able to deliver consistently low friction in elastomer/metal and plastic/plastic contacts across a wide temperature range. It performs effectively even at temperatures as low as –25 °C, which makes L 25 DL Barrierta suitable for door seals and systems, particularly on trains, to help them maintain stable actuating forces and controlled pressure variations in tunnel operation. Kluber Barrierta L 25 DL also absorbs part of UV radiation, which is found in direct sunlight, so using this lubrications help seals remain functional for longer.

Applications for which Kluber Barrierta L 25 DL is designed for is lubricating seals on train doors, it has also been a special lubricant for optical equipment. 

Also available in other sizes: 180g and 10kg.
