Wiper WPM 16x22x3/4 NBR+Stal

The WPM 16x22x3/4 NBR+Stal wiper ring is an essential element for protecting the glands of hydraulic cylinders against external contamination. Thanks to its design, it effectively prevents mud, water and dirt from entering the system, thereby protecting the seals and the piston rod surface against accelerated wear. This wiper is made of oil-resistant NBR rubber mounted in a steel case, which ensures a durable and secure fit in the housing. This design is intended to be press-fitted into the housing, which ensures firm retention even in difficult operating conditions. The flexible rubber lip fits precisely against the piston rod surface, effectively cleaning it of dirt and moisture during the working stroke of the cylinder. Materials: - Working part: NBR (nitrile rubber) – resistant to oils and greases. - Case: steel – provides rigidity and stable fixing. Dimensions: - Inner diameter (d): 16 mm - Outer diameter (D): 22 mm - Height / thickness (H): 3/4 mm Size in inches: - 0.63" × 0.87" × 0.12" The ring is used in the glands of hydraulic cylinders, in working mechanisms of construction and agricultural machinery, and in other systems exposed to mud, dust and water. Thanks to its modern design, the ring provides effective protection against contamination, easy installation and a durable fit in the housing.
