Oberdorfer 7130 Shaft Packing – PTFE Replacement Part
The Oberdorfer 7130 is shaft packing in PTFE. Packing seals a rotating shaft by being compressed into a stuffing box, and Oberdorfer lists packing alongside lip and mechanical seals as one of the dynamic sealing options across its pump range.
Packing consolidates in the first hours of running, so expect to readjust the gland shortly after a repack and then again once it has settled.
Inspect the shaft or sleeve where the packing runs. A grooved surface will chew through new packing quickly.

Frequently Asked Questions
Q: How much should the gland drip?
A few drops a minute with the pump running. A completely dry gland is running too tight and will score the shaft.
Q: How many rings does the box take?
That depends on the pump and the depth of the box. Count the rings that come out before they go in the bin.
Q: Can new packing be added on top of old?
It is a false economy. The old material is already consolidated and will keep the new rings from sealing.
Q: Why does new packing keep needing adjustment?
It consolidates as it beds in. Expect two or three small adjustments in the first hours and then long stability.
