Rectangular Gasket, Rietschle, V-VCA-VCE, Part# 520611 – vacstellar

Rietschle pumps are solid machines that run for years. But even the best ones need the right seals to stay in top shape. This rectangular gasket, part number 520611, is one of those key pieces that sits between the pump body and the head.

It is made from C-4401 material – a strong mix that handles oil and heat without breaking down. When you tighten the bolts, it presses flat and fills every small gap. That means no oil leaks and full vacuum power.

This gasket is made for the VCA25 and VCE25 models. These are the smaller pumps you see in workshops, labs, and light manufacturing. If your pump is starting to show a little drip or the suction is dropping, this is often the first part to check.
