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.

FAQ

Common questions

How do I choose between PTFE, graphite and aramid packing?

Match the grade to the dominant stress: chemical attack points to PTFE or graphite PTFE, temperature and pressure point to graphite fiber, abrasion points to aramid. Send us the media, temperature, pressure and shaft speed and we will confirm.

Can you supply die-formed rings?

Yes — rings are formed to your stem or shaft diameter, with the joint angle and compression allowance calculated for the application.

What is the minimum order?

Small trial orders are possible for standard cross-sections. Mixed pallets with different sizes are normal for us.
