YAMAKATO 3/4" ID Heat Shielded Fire Thermo Armor Fire

YAMAKATO's 3/4" ID Heat Shielded Fire Thermo Armor Fire Sleeve is a 5-foot silicone-coated fiberglass sleeve designed to protect hoses, fuel lines, wiring, and cables from extreme heat, abrasion, and flame exposure.

This heavy-duty protective sleeve combines a fibreglass inner core with a durable silicone outer coating to offer thermal insulation, abrasion resistance, and temporary flame protection where space is limited. Built for automotive, industrial, and marine applications, the sleeve fits 3/4" inner diameter hoses and comes with stainless-steel clamp compatibility for secure installation. Temperature tolerance covers continuous exposure from -65°F to +500°F and short-term exposure to much higher temperatures, making it a practical choice for areas near exhausts, turbochargers, and engine bays.

How does this sleeve protect hoses and wiring under high heat?

The silicone-coated fiberglass construction reflects radiant heat while the fibreglass core adds insulating mass to slow heat transfer. It also resists abrasion and chemical exposure, extending service life of protected components in hot environments.

• Continuous temperature range: -65°F to +500°F (-54°C to +260°C)
• Short-term heat resistance up to 2000°F–3000°F for brief exposures
• Silicone coating cleans easily and resists oil and grease
• VW-1 flammability rating for added safety

Will this sleeve fit my hose, and how is it installed?

The sleeve is specified for a 3/4" (19.05 mm) internal diameter and supplied in a 5-foot (1.52 m) length, allowing trimming to custom sizes. Installation is straightforward: slide the sleeve over the hose, cable, or line and secure the ends with compatible clamps or ties.

• Nominal ID: 3/4" (19.05 mm)
• Length: 5 ft (1.52 m) – easily cut to fit
• Suitable clamps: 20–25 mm stainless-steel hose clamps
• Works on fuel lines, brake lines, hydraulic hoses, and wiring harnesses

What environments and industries is this sleeve suited for?

This product is built for demanding situations where heat, abrasion, or incidental flame exposure threaten equipment. It's commonly used in automotive engine bays, industrial machinery, marine systems, and motorsport installations to protect critical lines and wiring.

• Automotive and motorsport: near exhausts, turbos, headers
• Industrial equipment: hydraulic and oil lines
• Marine systems: engine compartments and steam-prone areas
• Any application requiring compact, high-temp protection

How durable and maintainable is the silicone coating?

The silicone outer layer provides abrasion resistance, water repellency, and easier cleaning than bare fibreglass. It protects the inner fibre from mechanical wear and contaminants while keeping flexibility for routing in tight spaces.

• Silicone coating resists oils, greases, and road grime
• Easy to wipe clean and inspect without specialized tools
• Maintains flexibility across rated temperatures
• Layered construction shields inner fibre for longer service life

Who is this for: The YAMAKATO 3/4" Heat Shielded Fire Thermo Armor Fire Sleeve is aimed at mechanics, fabricators, motorsport teams, marine technicians, and DIY vehicle owners who need compact, high-temperature protection for hoses, lines, and wiring. Choose this sleeve if you require a short-length, tough, silicone-coated solution that balances thermal resistance, abrasion protection, and ease of installation for confined engine or equipment spaces. A 12-month support policy from the seller is included for peace of mind.
