Description

Tefapak RAM 220 Gland Packing

The RAM 220 gland packing is made of PTFE and specially selected ramie fiber with a particularly high resistance to friction wear. This packing is braided in square profiles, which during this process is deeply impregnated with PTFE dispersion. Because the fiber for packing production is not bleached with chemical treatment, it keeps its full original strength and natural ivory-pale yellow color.

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.
