Lumaco M4B-3.0-6.0 Stem O-Ring, Buna, Replacement Part, Use for Lumaco Sanitary Minidisc® Valve, 1 Each

Lumaco M4B O-Ring serves as a vital sanitary replacement component specifically designed for the Lumaco Minidisc Valve.

The stem O-ring is engineered to form a robust seal between the valve stem and the valve body. This critical function prevents process fluids—including liquids, powders, or slurries—from leaking along the stem and infiltrating the stem housing, ensuring efficient and secure operations.

Made from Buna, this O-ring delivers superior resistance to petroleum-based oils, fuels, hydraulic fluids, and silicone greases. This durability is essential in various industrial applications where exposure to these substances is common.

Buna retains its shape under pressure, ensures a tight seal over time. This feature is crucial in preventing leaks, which can lead to costly downtime and maintenance.

Designed to withstand friction and wear from the valve stem's movement, Buna O-rings contribute to a longer lifespan, thus reducing the frequency of replacements and associated costs.

Lumaco's Minidisc sanitary valve features leak detector holes, providing immediate alerts if the O-rings become worn or begin to leak. This proactive approach enhances safety and reliability in operations.
