O-ring, 140 x 5 mm – Viton, Part# 48656700 – vacstellar

Description

This O-ring is made for those important jobs. With a 140 mm inner diameter and a 5 mm thick cross-section, it’s built to seal large flanges, chamber doors, or pipe connections.

Getting the size exactly right is key. A 140×5 mm O-ring fits snugly into a specific groove. When you tighten the connection, the ring compresses evenly. This creates a continuous barrier that air or fluids cannot pass through.

For vacuum systems, the material is just as important as the size. This ring is made from Viton® (FKM). Viton® is a top choice for vacuum and industrial use because it’s very resistant. It handles high temperatures and aggressive chemicals much better than standard rubber. This means your seal stays reliable longer, even in tough environments.

This specific part (48656700) is compatible with popular Pfeiffer vacuum pumps. It ensures a perfect fit and optimal performance for your equipment.

Whether you’re doing routine maintenance or a specific repair, using the correctly sized, high-quality O-ring makes all the difference. It keeps your vacuum strong and your system running smoothly.
