Soft PTFE Coated Fiberglass Sleeve: High Temperature, Heat / Chemical Resistant & Thermal Insulating for Wire, Cable, Hose Protection 
550°F / 287°C Maximum Continuous:

This high temperature, heat / chemical resistant and thermal insulating PTFE coated fiberglass sleeve offers the advantage of a non-asbestos material with a higher temperature range and with excellent resistance to almost all solvents, caustics and acids.

The base fiberglass fabric is rated to 1000°F / 537°C while the PTFE coating melting point is 620°F / 327°C.

Available in 1/16" (thin wall) and 1/8" (thick wall) wall thickness.

Inside Diameters available from 0.25" up to 5.0".

The PTFE is applied to the sleeve by dipping the sleeve through an immersion tank of liquid PTFE dispersion.  The sleeve is then air dried as it leaves the dip tank.  The result is a PTFE coating on the sleeve which is soft, robust and flexible; however, it can be abrasively removed from the sleeve with aggressive fingernail scraping, resulting in a thinner and thinner layer of ptfe remaining with each pass.

The PTFE also causes the yarns to be sealed and the small gaps between the yarns filled, resulting in an almost air-tight / liquid-tight sleeve wall.
