The 107 Series U-cup seal is one of System Seals’ most popular designs used in standardduty applications. The symmetrical design utilizes an O-ring loader to maximize lip force, making it the preferred choice in lower-pressure applications. The symmetrical design ensures that the seal lip forces are equal for every cross section and diameter. The 107 is widely used in standard- to moderate-duty hydraulic applications. Manufactured in a variety of materials and sizes from 6 mm up to 2100 mm in standard and custom diameters.
