O-ring, 39.35 x 2 mm – Buna, Part# 320230 – vacstellar

This little O-ring might look small, but it does a big job. It creates a perfect seal where oil and air meet inside your pump.

Made from Buna rubber – the same strong, oil-resistant material used in the original pump. It measures exactly 39.35 mm across and 2 mm thick.

It slips right into place on Rietschle VC300, VC400, VC500 and VC700 models. These are the popular oil-lubricated rotary vane pumps you find in factories, hospitals, labs and workshops.

When this O-ring gets old or damaged, you might notice oil leaks, weaker suction or strange noises. Replacing it is one of the easiest ways to bring your pump back to full power.

It’s the real OEM part, not a cheap copy. So it fits perfectly and lasts just like the one that came from the factory.

Changing it takes just a few minutes during regular service. No special tools needed. Just pop out the old one, clean the groove and slide in the new one.

Keep your pump happy and your work moving smoothly with this replacement.VC500
