Six constructions, one purpose: hold the seal
Braided gland packing is the workhorse of valve and pump sealing. We braid square-section packing from PTFE, graphite, acrylic and aramid yarns — each grade selected for a different combination of temperature, chemical attack and shaft speed.
Every grade is supplied as continuous square braid, cut to length, or as die-formed rings to drawing. Impregnation and lubrication are matched to the yarn, not applied as an afterthought.
- Square braid from 5×3 mm to 38×6 mm
- PTFE, graphite, acrylic and aramid yarns
- Impregnation and lubrication matched to the duty
- 5 kg or 10 kg rolls in export cartons

Choosing between the three families
Chemical resistance first
PTFE and graphite PTFE packings cover pH 0–14 and most aggressive media. Start here for acids, solvents and caustics.
Heat and pressure first
Graphite fiber packing runs to 560 °C and 250 MPa — steam valves, power plants, thermal circuits.
Abrasion first
Aramid fiber packing is braided for slurry pumps, mining duty and media carrying solids.
