SEAL - QUAD RING (Hyster HY1570344)

A damaged quad ring can allow fluid or gas to bypass the sealing surface, reducing system pressure. During inspection, a quad ring may show wear, cuts, or extrusion that compromises its seal. The quad ring type uses a four-lobed cross-section to provide a more stable seal than a standard O-ring in dynamic applications. Keeping a quad ring in sound condition helps prevent leaks that can lead to component contamination or premature wear. This aftermarket replacement part references the Hyster catalog number HY1570344. Verify the serial number or application, then call (562) 693-7748. The part is a seal, specifically a quad ring, which functions by creating a barrier between mating surfaces.
