248-7178 SEAL O RING

Description:
O-Rings are used for static sealing and some dynamic applications.
 
Features:
O-Rings are made from materials that match the fluids, temperatures, and pressures found in engines and machines. The materials are resistant to wear and extrusion, providing superior resistance to seal compression tools. Additionally, certain O-Rings are coated with PTFE to minimize seal twisting and cutting during installation.
Our O-Ring sizes are regularly subjected to tight tolerances to ensure they sit properly in the seal channels with the required compression.
With over 2,500 different sizes and materials, Cat O-Rings provide the best solution for your O-Ring needs and other mobile equipment applications.
Sealing systems protect more expensive parts from leaks and contamination. Protect your investment with Original Seals.
