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.

What size do I need for heater lead wires?
Most heater leads fall in the 3 mm to 8 mm nominal range (SYN-HTFS-003 to SYN-HTFS-008). Measure the lead or pair and pick the size whose expansion range covers it comfortably.
Is the sleeve suitable for process plants?
Process and chemical plants use it over instrument and heat-trace cables in hot zones. Check chemical exposure with us too, since fibreglass and its finish behave differently from polymer sleeves.
Do you supply dealers and distributors?
Yes. Dealers usually take a spread of sizes such as 3, 6, 8, 10 and 12 mm. Our minimum order is 500 metres; confirm the size split and volume pricing in the quotation.
What HSN code applies to fibreglass sleeving?
Glass-fibre sleeving generally falls under HSN chapter 7019. We state the exact HSN code and GST rate on the quotation and invoice.
