Insulation Heat Shielded Fire Sleeve, 3/4″ ID
The Fire Sleeve features a silicone rubber-coated fiberglass construction designed to protect hoses, wires, and fuel lines from high temperatures. It is rated to withstand 800 degrees F continuous heat and 2200 degrees F intermittent heat. The inner sleeve uses fiberglass, with a silicone coating for abrasion resistance and easy cleaning. This option is suitable for brake lines, fuel lines, wiring harnesses, and cables, and can guard welding lines during operation.
Key considerations: suitable for 3/4″ ID applications, VW-1 flammability rating, sturdy silicone outer layer; practical for automotive and mechanical uses where heat exposure is high and movement is expected.
Insulation Heat Shielded Fire Sleeve, 1″ ID
This 1″ ID sleeve continues the same silicone-coated fiberglass approach, offering robust heat protection for automotive hoses, wiring, and electrical bundles. Withstand ratings and flammability align with the 800°F continuous / 2200°F intermittent guidance. The sleeve’s silicone layer reinforces abrasion resistance and simplifies cleaning, making it a durable choice for high-temperature environments.
Important considerations: ideal for larger wiring bundles or hoses that require a 1″ diameter sleeve, compatibility with VW-1 fire rating, and reliable performance across automotive and industrial settings where heat exposure is persistent and variable.
Design Engineering Fire Sleeve And Tape Kit
This kit provides a practical bundle for protecting hoses and electrical wiring from heat. It offers fire sleeve coverage plus tape for securing insulation around bundles. The sleeve withstands 500 degrees F continuous heat and 2000 degrees F intermittent heat, making it suitable for a broad range of automotive and industrial applications where heat is intermittent but intense.
Considerations: convenient for temporary or semi-permanent installations, comprehensive for bundling and protection, and a cost-effective way to add heat protection to existing wiring and hoses.
1/2″ ID Fire Sleeve, Silicone Coated Fiberglass
This sleeve offers a 1/2″ inner diameter with a 5-foot length. It is designed for standard silicone rubber-coated fiberglass, suitable for protecting hoses and wires against high temperatures. Operating range extends from -60°C to 260°C, with VW-1 flammability and fiberglass inner sleeve. Silicone coating may have a mild odor when first heated, which is normal in some silicone compositions.
Important considerations: best for smaller bundles or tight spaces, ensure accurate identification of required inner diameter before purchase, and check for potential odor during initial use.
1/4″ ID Fire Sleeve, Silicone Coated Fiberglass
With a 1/4″ inner diameter and 5-foot length, this sleeve is designed for compact wiring and small-diameter hoses. It shares the silicone-coated fiberglass construction, providing heat resistance and abrasion protection. Operating range remains -60°C to 260°C with VW-1 flammability and fiberglass inner sleeve. Note that silicone coatings can emit a slight odor under high heat, which is typical for some formulations.
Considerations: ideal for tight engine bays, reliable protection for small-diameter lines, and compatibility with common automotive insulation standards.
1″ ID Fire Sleeve, Black
This 1″ ID sleeve from STEBER uses a silicone-coated fiberglass construction with a 5-foot length designed for medium-to-large size bundles and hoses. It features an operating temperature range to -60°C through 260°C and VW-1 flammability, providing durable protection against heat for automotive, HVAC, and industrial wiring and piping. The sleeve’s robust materials make it suitable for enduring high-heat environments and mechanical wear.
Buying Guide: Key Considerations For Choosing Fire Sleeves
When selecting a fire sleeve, buyers should balance diameter, length, heat resistance, and installation practicality. Consider these factors to ensure optimal protection and fit for your application.
- Diameter and Length: Measure the external diameter of hoses or bundles and choose a sleeve that allows for a comfortable but snug fit. Longer sleeves are useful for extending protection across bends and joints.
- Heat Resistance: Look for sleeves rated for continuous heat and intermittent peaks that match your environment. Silicone-coated fiberglass sleeves often offer robust protection, typically around 500–800°F continuous and up to 2000–2200°F intermittent.
- Flammability Rating: VW-1 or equivalent ratings indicate a level of fire resistance appropriate for automotive and industrial settings. Confirm compliance with relevant safety standards for your region or application.
- Material Durability: Silicone coating adds abrasion resistance and easier cleaning, while fiberglass cores provide structural integrity under heat. Consider resistance to oils, fuels, and solvents if used near such fluids.
- Installation and Reusability: Some sleeves are designed for quick installation with easy securing methods, while others are part of a kit with tapes for bundling. Reusable designs can save time in maintenance or temporary setups.
- Environmental Exposure: Outdoor or UV exposure requires sleeves with UV-resistance and weatherproof outer layers to maintain performance over time.
- Odor Considerations: Silicone coatings may emit a mild odor when first heated; this is generally normal but may be a factor in enclosed spaces.
For system-wide protection, evaluate whether to use sleeves individually or as part of a kit that includes additional mounting or securing materials. In automotive or HVAC projects, ensuring compatibility with fuel lines, hydraulic hoses, and electrical wiring reduces the risk of heat-related degradation and improves overall reliability.
