Dual-Purpose Piston and Piston Rod Seals

VAD Type Universal Rod and Bore Seal adopts an innovative lip seal structure. Through the synergistic effect of polyurethane (PU) and nitrile rubber (NBR) composite materials and star rings, it achieves excellent sealing performance in the full range of high and low pressures. It is resistant to vibration, extrusion, low temperature adaptability and ultra-long life. It is designed by Ruichen Seals specifically for harsh working conditions such as forging machines, heavy hydraulic cylinders and mobile equipment.

Ruichen Seals manufactures high-quality, reliable BA-Type Universal Rod and Bore Seals for heavy-duty hydraulic equipment. These symmetrical seals are suitable for the demanding working conditions of forging machines, construction machinery travel devices, and hydraulic cylinder piston rods. They offer excellent resistance to vibration, pressure spikes, extrusion, and low-temperature sealing, maintaining a stable seal even under extreme conditions.

professional piston rod seal manufacturer in China, our symmetrical seals feature a sophisticated cross-section design that allows for direct installation into integral grooves.
