Dust wiper VAY

VAY wipers are protective seals for hydraulic cylinder rods, available in a standard version with a single lip and in a double-lip version for increased protection against pressurized water and fluid mud. This makes them useful in applications where the rod is exposed not only to dry dust, but also to water or mud actively flowing over its surface — a common situation with foundation, drilling, and wetland equipment. Both versions, with complete dimensions, are available at hydsealstore.ro, with comparative application tables.

Technical Specifications and Role of VAY Wipers in Sealing

The standard version has a single wiping lip, effective for dust and dry particles — the appropriate solution for most ordinary construction site applications. The double-lip version adds a secondary lip that forms a capture chamber between the two lips — it blocks pressurized water and fluid mud that would pass through a standard wiper. The intermediate chamber acts as an additional barrier, while internal drainage prevents the accumulation of contaminants. Made of polyurethane or polymer-metal combinations, depending on the application. They operate between -30°C and +100°C. The other sealing components of the cylinder are available in the range of hydraulic seals.

Industrial Applications and Compatibility with Hydraulic Cylinders

Standard VAY is chosen for construction machinery exposed to dry dust and fine particles, agricultural equipment operating in the field, and cylinders with moderate dry contamination. Double-lip VAY is chosen for excavators operating in wetlands, foundation and drilling equipment exposed to pressurized mud, machinery that frequently passes through water, and any cylinder where water is the main contaminant. The additional cost of the double-lip version pays for itself with a single avoided maintenance cycle, especially on machinery with long and expensive rods. Both versions, standard and double-lip, are available in the range of hydraulic wipers.

Selection and Installation Criteria for VAY Wipers

Choose the version according to the predominant type of contaminant: dry dust, fine particles, and ordinary construction site environments — standard VAY; water, fluid mud, wetlands, or frequent exposure to splashes — double-lip VAY. For machinery operating alternately in both conditions (dry summer, winter with snow and mud), the double-lip version is the safe choice. The groove must be thoroughly cleaned and inspected. The VAY wiper is inserted with the main lip facing outward, paying attention to the orientation of the secondary lip in the double-lip version. The piston seals that complete the system are available in the range of piston seals.

Advantages of Purchasing VAY Wipers from Hydraulic Seals Store

VAY wipers are available in different configurations, which allows them to be selected according to the environment in which the cylinder operates. The standard version is suitable for ordinary contamination with dust and particles, while the double-lip model provides additional protection when the rod is exposed to water or mud.

Before ordering, it is useful to determine what type of contaminant most often occurs in the cylinder area and to check the groove dimensions. At Hydraulic Seals Store, you can find the available VAY versions and request assistance in selecting the appropriate profile. Correct installation, with the correct orientation of the lips, is essential for the operation of the wiper.
