DAI is a single-acting elastomeric dirt wiper with bearing segments. Main and secondary seals, as well as the guidance of modern sealing systems, require reliable protection of the wiper. Dirt, dust, and moisture must not contaminate the working medium and, most importantly, must be kept away from the pressure seal edges. Depending on the application, a simple wiper with or without metal reinforcement and a double wiper with or without pressure relief can be used. DAI wipe seals can be used with mineral oil and many other types of hydraulic fluids. Special versions are available for use at high ambient temperatures. Care must be taken to ensure that there is no pressure buildup inside the wiper, including grease lubricant pressure. DSH Seals’ DAI wiper seals are designed referring to Merkel company’s P6,  Hunger’s AI.
