Frequently asked questions

What exactly is gland packing?

A braided sealing cord with a square profile that is laid around the shaft in the stuffing box of a pump or valve. Tightening the gland follower compresses the cord slightly so it seals the shaft without blocking rotation.

Which gland packing materials are there?

Among others pure and graphited PTFE, expanded graphite, aramid, carbon fibre, phenolic fibre and ramie fibre, also in combinations such as aramid-reinforced corners.

Up to what temperature is gland packing resistant?

Depending on the material 120 to 600 °C; the temperature resistance and dimensions are listed per packing on the product page.
