3M Fire Barrier Putty Sleeve Kit DT 200
The DT 200 kit provides a ready-to-install solution for complete cable or blank firestop installations. It is tested up to 4 hours for fire-rated through-penetration systems in accordance with ASTM E814 (UL 1479). Installation is eased by the absence of a gasket requirement, enabling faster on-site work while maintaining fire resistance.
3M Fire Barrier Putty Sleeve Kit DT 400
The DT 400 kit is designed for larger cable or blank firestop installations. Like the DT 200, it is tested up to 4 hours for fire-rated through penetration systems in accordance with ASTM E814 (UL 1479). The kit format supports straightforward installation without the need for gaskets, helping reduce installation time and complexity.
1-1/2 ID Fire Wrap 25″ Length
This fire wrap features a 1-1/2 inch inner diameter with a 25″ length, heat shielded protection, and a silicone-coated fiberglass construction. It includes a Hook and Loop Closure for easy fastening. Rated to withstand direct heat up to 500°F, it supports temperatures from -60°C to 260°C, and carries VW-1 flammability, making it suitable for critical wiring and hose protections in demanding environments.
5/8 ID Fire Wrap 25″ Length
The 5/8 inch ID fire wrap matches the same construction as the larger wrap, offering a compact 25″ length with a Hook and Loop closure. It provides heat shielding for wiring and hoses, with a silicone-coated fiberglass composition rated to handle heat exposure similar to larger wraps. Suitable for routine protection needs in tighter installations.
ReHaffe Kevlar Sleeves
ReHaffe kevlar arm sleeves are designed to deliver thermal and cut protection for arms during welding, metalwork, and other high-heat tasks. Made with 100% Kevlar fabric, these sleeves are lighter than some alternatives and offer EN388 Level 3 cut resistance with level 2 abrasion resistance. They tolerate temperatures up to about 200°C, and their non-toxic, odor-free composition supports prolonged wear in industrial settings.
Buying Guide
- Heat resistance and temperature range: Choose sleeves with clear limits (e.g., up to 200°C or higher) that match your work environment and exposure duration.
- Material and protection type: Consider silicone-coated fiberglass wraps for heat shielding versus Kevlar sleeves for cut resistance and puncture protection.
- Installation ease: Kits that require no gasket and use simple closures save time on-site; look for Hook and Loop or straightforward mounting options.
- Diameter and length: Ensure inner diameter (ID) and total length cover the targeted cables, hoses, or limbs without restricting movement.
- Standards and certifications: ASTM E814/UL 1479 compliance, VW-1 ratings, and EN388 certifications indicate performance under recognized benchmarks.
- Durability and reuse: Reusable sleeves with durable stitching and heat-resistant fabrics provide cost benefits over single-use options.
- Application scope: For through-penetration firestop, prioritize products that explicitly state fire rating duration and installation compatibility.
- Maintenance and replacement: Check for wear indicators or signs of degradation, especially in high-heat or abrasive environments.
