AP Racing/ Lockheed Hi-Temperature Caliper Piston Seal, Each, Choose Size

Genuine Lockheed/ AP Racing High Temperature Seal-in-bore brake caliper piston seals:

• These seals are manufactured specifically for racing use.
• Sold individually.
• Typical applications:
  • LD19 are CP4900-193, 1.62″ dia
  • LD20 are CP4900-162, 1.75″ dia
  • LD65 are CP4900-165, 36mm/ 1.42″ dia
• These seals are for AP/Lockheed seal-in-bore calipers only. They do not fit AP Racing seal-on-piston calipers or any other brand of calipers. Brakes are a critical safety component. We strongly recommend against trying to use these seals in other brands of calipers, even if the nominal piston size is the same. The results of brake system failure can have devastating effects!
• These seals get compressed to size when they are installed in the caliper bore. This is required for a tight seal. They will be slightly oversize (up to about 0.10″ larger than the nominal size) when they are loose. They will not fit tight against the piston until they are installed in the caliper bore.
