1727 Multi-Lon

Chesterton 1727 Multi‑Lon™ is a premium PTFE-based packing designed for pumps, mixers, and agitators handling aggressive chemicals and abrasive slurries. Its interlaced PTFE braid, embedded with lubricants, resists hardening and extrusion under high pressures and temperatures (up to 500 °F/260 °C) and across the full pH range.

Offering low friction, excellent dimensional stability, and robust sealing performance, 1727 reduces maintenance needs and extends equipment life—perfect for continuous-operation industrial environments.
