Wiper GA
GA wipers are protective seals with a simple profile for standard hydraulic cylinders in mobile and stationary industries. A reliable and affordable solution for applications with moderate contamination — dry dust, fine particles from workshops or light construction sites. They can be found in many standard hydraulic cylinders where environmental conditions are not extreme and where regular preventive maintenance is possible. They are the right choice when the price-to-service-life ratio matters more than maximum resistance. The profile, dimensions, and materials are available at hydsealstore.ro, with filters by rod diameter and groove type.
Technical Characteristics and Properties of GA Wipers for Hydraulic Applications
Made of polyurethane (better resistance to mechanical wear, the standard choice) or NBR (more flexible at temperatures below -30°C and compatible with fluids where polyurethane fails). The simple single-lip profile ensures uniform contact around the entire circumference of the rod. They operate between -30°C and +100°C. They are installed in standard grooves, compatible with the vast majority of cylinders on the Romanian market — both European and Asian cylinders with ISO dimensions. The material should be selected according to temperature and fluid, not just price. Complementary components are available in the range of hydraulic seals.
The Role of GA Wipers in Protecting Hydraulic Cylinders and Preventing Contamination
GA is chosen for cylinders with moderate exposure to dry dust and fine particles, equipment with regular maintenance at scheduled intervals, and applications where the affordable price of the wiper matters. Replace it preventively during every cylinder overhaul, regardless of its visual condition — a seal that appears to be in good condition may already be microscopically degraded and will fail shortly after the installation of new internal seals, which cancels out the effort of the overhaul. The cost of a GA wiper is insignificant compared to a repeated overhaul. Versions for more aggressive conditions are available in wipers, with options for environments with abrasives or moisture.
Selection and Installation Criteria for GA Wipers
If the environment contains coarse abrasives, heavy mud, or pressurized water — not GA, but GHP, DKBI, or VAY with double lips. GA is for standard moderate contamination, not extreme conditions. Confirm the maximum temperature and fluid type before ordering. The groove must be thoroughly cleaned and inspected for burrs and corrosion. The lip must face outward, with care during insertion to avoid deforming the profile. Lightly lubricate before the first stroke. The rod seals that complete the system are available in seals.
Advantages of Purchasing GA Wipers
GA wipers are intended for hydraulic applications where the level of contamination is moderate and specialized profiles for extreme conditions are not required. Hydraulic Seals Store offers polyurethane and NBR versions, allowing the material to be selected according to temperature and the fluid used.
To identify the product, the rod diameter and groove dimensions must be checked. If the cylinder operates in heavy mud, with pressurized water, or with coarse abrasive particles, it is worth considering another profile from the range. If the application is standard, we can help identify the appropriate GA size.
