UL 3172 Silicone Rubber Fiberglass Braid Wire for Saudi Arabia and Dubai
UL 3172 is a silicone rubber insulated wire with an outer treated fiberglass braid, rated 200°C and 600V AC under UL AWM Style 3172. The construction combines the thermal stability and electrical insulation of silicone rubber with the abrasion resistance and mechanical protection of the fiberglass braid outer covering — making UL 3172 the specification for high temperature internal wiring applications where the wire must be routed through, past, or in contact with hot metal surfaces, conduit edges, or structural elements inside industrial equipment.
The distinction from bare UL 3135 silicone wire is mechanical: UL 3172’s fiberglass braid resists cutting, chafing, and abrasion at wire routing points in enclosed equipment, extends the wire’s service life in applications with vibration or repeated mechanical flexing, and provides an additional layer of insulation integrity if the silicone rubber insulation is nicked or compressed during equipment assembly. In Saudi Arabia’s industrial equipment sector and Dubai’s manufacturing and maintenance operations, UL 3172 is specified wherever the routing environment demands covered wire rather than bare silicone.

Applications in Saudi Arabia and Dubai
Industrial oven and furnace internal wiring (Saudi Arabia)
Industrial ovens, curing furnaces, and process heaters in Saudi Arabia’s manufacturing and petrochemical sectors specify UL 3172 for internal wiring where leads are routed through metal conduit or past structural edges inside the heated chamber — the fiberglass braid protecting the silicone insulation from abrasion at conduit entries and routing clips.
Heating element connections (Dubai equipment OEMs)
Equipment manufacturers in Dubai Industrial City assembling industrial heating equipment for the GCC market use UL 3172 for the connections from the control panel internal wiring to the heating element terminals — where the wire crosses through insulated panels and passes through grommets in hot metal walls. See also: UL 3135 bare silicone wire for open-routing high temperature applications.
Motor leads in vibrating equipment
Motor lead connections in equipment subject to vibration — industrial mixers, compressors, and pump drives — where UL 3172’s fiberglass braid resists the chafing and insulation wear that bare silicone wire develops at routing contact points under repeated vibration cycles over a long equipment service life.
Other applications
- HVAC equipment heat exchanger zone internal wiring
- Transformer internal leads with routing through metal structures
- Commercial kitchen equipment — oven cavity wiring
- Gas appliance burner zone internal connections
