UL 3172 Silicone Fiberglass Wire

UL 3172 Silicone Fiberglass Wire for High Temperature Internal Wiring

UL 3172 wire is a silicone fiberglass insulated AWM wire used in internal wiring applications where higher temperature resistance and a more durable lead wire construction are required. Compared with ordinary silicone wire, UL3172 is often selected for equipment sections exposed to greater heat or where additional fiberglass protection is preferred for internal routing.

This style is commonly reviewed for heating equipment, ovens, furnaces, appliance hot zones, and other electrical assemblies where standard internal wiring is not suitable for long-term use. The combination of silicone insulation and fiberglass braid makes UL3172 a practical choice for high temperature lead wire applications in OEM and industrial equipment.

Buyers often choose UL3172 when the internal wire needs to remain stable in a thermal environment while still fitting the routing and installation requirements of the assembly. It is especially useful in equipment where lead wires pass through protected but consistently hot sections.

When sourcing UL3172 wire, buyers usually confirm conductor size, conductor finish, insulation color, package format, and the actual operating condition. For OEM projects, it is also common to review whether the wire is used for fixed internal routing, heating sections, or equipment lead connections before quotation.

If the application requires a more flexible general silicone wire, UL3135 may be suitable. If the project requires high voltage silicone wire, UL3239 may be more relevant. UL3172 is more appropriate when the buyer needs a silicone fiberglass wire for higher-temperature internal lead use.
