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 heat-treated fibreglass sleeve used for motor lead wires?
Yes. Motor, pump and alternator makers use it over lead-out wires and joints near the winding. Send the lead diameter, insulation class and curing temperature and we suggest a size and confirm the grade data.
