Heat-treated vs standard fibreglass sleeve
Heat treatment gives the braid its bronze finish and is a separate construction from standard white fibreglass sleeving.
−40 to +800 °C catalogue reference
For radiant heat near furnaces, elements and exhausts. Confirm continuous and peak exposure with the grade data before you specify.
Standard fibreglass sleeve
White expandable fibreglass braid with 1500-denier yarn for general cable covering. Thermal and electrical ratings on request.
Aramid / Kevlar sleeve
When cut and abrasion resistance matter as much as heat, compare aramid braided sleeving.

Does the sleeve stop molten metal splash?
Heat-treated fibreglass handles radiant heat well, but heavy molten-metal splash needs a dedicated splash-guard product. Describe the exposure and we will advise whether this sleeve is right.
Can it protect thermocouple cables near furnaces?
It is widely used over thermocouple and compensating cables near furnaces and ovens. State the surface temperature, distance from the heat source and exposure time so we can confirm suitability.
Can you support power-plant maintenance shutdowns?
Yes. For shutdowns, send the sizes and metres early and we confirm availability and dispatch date in the quotation.

Glass-fibre sleeving generally falls under HSN chapter 7019. We state the exact HSN code and GST rate on the quotation and invoice.
