RaceFlux Fire-Retardant Silicone Fiberglass Hose Sleeve
RaceFlux Fire-Retardant Silicone Fiberglass Hose Sleeve
Armor for hoses running near heat: this fire-retardant sleeve pairs a silicone outer layer with a fiberglass inner braid, protecting hoses, wires, and cables at continuous temperatures up to 500°F and intermittent exposure up to 3,000°F. In direct flame, the silicone outer layer transforms into a protective, non-flammable silica coating while the fiberglass insulates against radiant heat — the same approach used in aerospace and motorsport to protect critical components in an engine fire.
Key Features
- Rated 500°F continuous, 3,000°F intermittent exposure
- In flame, silicone converts to a protective silica (SiO2) coating over insulating fiberglass
- Extremely flexible, non-conductive, and highly abrasion-resistant
- Won't melt or become brittle over time; matte finish resists dirt pickup
Fitment & Compatibility
- Select the ID and length for your hose: 3/8" fits -3AN to -4AN, 1/2" fits -4AN to -6AN, 5/8" fits -6AN to -8AN, 3/4" fits -8AN to -10AN, 7/8" fits -10AN to -12AN (larger AN size is a snug fit — for runs over 5 ft, size up)
- Common uses: fuel and oil lines near headers, turbo plumbing, wiring in hot zones
Note: Seal cut ends with RaceFlux heat shrink seals for a finished, secured installation.
