3M Fire Barrier Putty Sleeve Kit DT 200
Best for through-penetration firestop when you need a compact, ready-to-use kit. This 2 inch round kit is tested for up to 4 hours in accordance with ASTM E814 (UL 1479). It covers complete cable or blank firestop installations without requiring additional gaskets, simplifying the install and reducing downtime. Ideal for electrical rooms or data centers where quick, compliant firestopping matters. Limitation: larger penetrations may require alternative sleeve sizes or combinations of products.
CrocSee 25ft Flame Retardant Split Wire Loom Tubing
Best for everyday wiring protection with flame retardant properties. The split loom features a 1/2 inch inner diameter and 25 feet of length, and includes a wire insertion tool to ease loading. Suitable for automotive, industrial, office, and home projects. Caution: ensure correct installation to maintain fire resistance across long runs and consider heat exposure from nearby equipment.
YesBes 120 FT Wire Loom 1/2 Inch
Best for long wiring runs needing economical protection and easy installation. The 1/2 inch split loom is made of polyethylene and can handle a wide operating range from -40°F to 200°F. It helps prevent damage from electrical fires and heat buildup. Limitations include the potential need for additional shielding in extreme heat or high-EMI environments.
Electriduct 1.5″ Flexo Remix PET Expandable Braided Sleeving
Best for high-temperature, flexible applications with expanded diameter. This sleeving expands from 1 3/8″ to 2 3/8″ and supports continuous operation from -94°F to 257°F, with a melt temperature of 482°F. It suits large bundles or equipment with dynamic movement. Limitation: it may be bulkier and not ideal for tight conduits or small spaces.
Pangda 50ft Split Wire Loom Tubing Flame Retardant Braided Sleeve
Best for broader, industrial-scale protection with flame retardant braided construction. The split design allows easy loading while the 50-foot length covers long runs. Suitable for automotive, marine, and industrial electrical wiring. Caution: braided sleeves can be bulkier and may require extra routing space in tight panels.
Buying Guide: Key Considerations For Fire Rated Conduit Sleeves
- Fire resistance requirements: Match sleeve or kit ratings to your local code and the fire rating needed for the penetration or enclosure.
- Installation ease: Ready-to-install kits save time; split loom designs simplify loading but may require careful routing.
- Temperature range: Select materials that tolerate your environment’s high and low temperatures.
- Physical protection: Braided sleeves offer abrasion resistance and flexibility for complex routes; rigid sleeves suit through penetrations.
- Size and length: Choose inner diameter and length that accommodate the wire bundle without excessive slack.
- Material safety: Flame retardant materials reduce risk, but verify chemical compatibility with cables and surroundings.
- Expansion and flexibility: For dynamic equipment, expandable sleeving reduces stress on cables during movement.
- Installation tools: Some products include insertion tools to speed up loading and reduce damage to wires.

It provides a fire rated seal around cables passing through walls or floors, preventing flame spread for a defined period.
Many split loom products offer flame retardant properties but verify their specific fire rating and code compliance for your project.
Yes, braided sleeving often handles high heat and provides flexible protection, but confirm temperature limits and fitment for your engine bay.
Measure the cable bundle diameter and add a buffer for easy installation and future expansion.
Some kits include tools or gaskets; if not, plan for standard insertion or cutting tools as needed.
Follow the product’s guidelines, maintain proper clearance, and ensure the assembly meets applicable fire codes and standards.
