Sealing ring, Copper- Becker U Series, Part# 94802300000 – vacstellar

This Sealing ring, Copper- Becker U Series, Part# 94802300000 is the exact replacement part you need. It is made from high-quality, soft copper, a material specifically chosen for its excellent ability to create a tight, reliable seal when compressed between metal surfaces. When you tighten a bolt or fitting against this ring, the copper deforms slightly, filling any tiny imperfections and creating a leak-proof barrier. It is used across a remarkably wide range of U Series models, including U4.70D, U4.70E, U4.70F, U4.70G, U4.70H, U4.70, U4.100D, U4.100F, U4.100, U4.100G, U4.100H, U4.400D, U4.400, U4.630D, and U4.630 pumps . Its primary function is to create a durable, leak-proof seal between metal components, which is essential for maintaining proper vacuum levels and preventing oil leaks .
