Silicone-coated or inner-fiber outer-silicone?

Coated braid is flexible and breathes; inner-fiber outside-silicone gives a thicker, more insulated wall for hotter leads. Wellele makes both builds.

What is the continuous temperature?

About 260°C for silicone fiberglass sleeving, used on motor and transformer leads. Confirm the exact class on the product page.

Silicone resists many oils and solvents; for strong solvents switch to fluoropolymer sleeving.

When the spec calls for heat, three silicone-and-glass builds come up. They share a high temperature class but differ in flexibility and wall.

Silicone-coated fiberglass sleeving is flexible and dielectric, the standard for motor leads and coils.

Inner-fiber / outer-silicone sleeving puts a braided glass core under a silicone skin, more body and abrasion resistance while staying flexible.

Extruded fiberglass sleeving is the rigid, highest-temp option for fixed bus and terminal protection.

Moving or bent sections → coated or inner-fiber/outer-silicone. Fixed high-heat bus → extruded. See more under products by material.

Silicone-coated fiberglass; inner-fiber/outer-silicone adds body but stays flexible.

Rigid, highest-temperature protection of fixed bus and terminals.
