Description
Spare O-Ring, Perbunan, DN 160 ISO-K is a replacement sealing ring for larger ISO-K vacuum flanges in the DN 160 nominal size. Fabricated from Perbunan elastomer, it provides the circumferential seal between ISO-K flange faces on vacuum pumps, process chambers, and laboratory vacuum lines. The part is supplied as one piece for maintenance and repair when the installed O-ring shows compression set, cuts, or leakage. Correct seating in the ISO-K groove and uniform clamp force restore the sealing line without altering flange hardware. Perbunan is a practical choice for many technical vacuum environments involving oils and related media. This spare O-ring from manufacturer WELCH is aimed at facilities that operate DN 160 ISO-K connections and need a straightforward elastomer replacement for service intervals or unplanned downtime. It fits standard DN 160 ISO-K flange geometry used across laboratory and pilot-scale vacuum equipment, supporting reliable reassembly when handled and compressed according to the host system’s installation practice and torque or clamp guidance.
