Product description

Ensure a leak-free environment in your professional workshop with the Snap-On ST0019121 O-Ring Seal. This precision-engineered elastomeric seal measures 29.75 x 3.53 mm and is a critical component for maintaining pressure in the hydraulic and pneumatic systems of tire changers, balancers, and lifts. Identified by the reference 8-13314A, this O-ring is manufactured from a high-quality nitrile or Viton compound designed to resist degradation when exposed to hydraulic oils, compressed air, and typical automotive chemicals. Its precise cross-section and diameter ensure a perfect fit within the gland, providing a reliable static or dynamic seal that prevents pressure loss and equipment contamination. Small but essential, the ST0019121 is the professional's choice for preventing messy leaks and ensuring the safe, efficient operation of Snap-On and John Bean service machinery.
