This type of product is designed for installation on the pistons of hydraulic and pneumatic cylinders as the primary sealing element.
With its distinctive asymmetrical construction of the sealing lips this product allows construction of pistons of lower total height. Its durability, low cost and flexibility even if machine parts are moderately damaged makes this product a very good choice for piston sealing (outer sealing) in hydraulic and pneumatic cylinders.
