O-ring Pusher Mechanical Seals

John Crane’s O-ring pusher seals are engineered for reliability. The Type 1648 is a high-performance single cartridge pusher seal designed to help prevent emissions leakage in most refinery and API 682-qualified applications. Classified as Type “A” O-ring pusher seals, the Type 1648, Type 2648 and Type 3648 are high-performance, low-emission cartridge seals. Their ability to safely and completely contain hazardous fluids makes them particularly suitable for operations such as refineries and petrochemical plants, where precise control over the sealing environment is critical.
