HellermannTyton Heat Shrink Tubing, Black, PVC, 12.7 mm Sleeve Diameter x 5m Length, 2:1 344-01270 LVR-12.7/6.4-PVC-BK

HellermannTyton 344-01270 LVR-12.7/6.4-PVC-BK Heat Shrink Tubing is engineered for high-performance cable insulation and protection. With a 12.7 mm original sleeve diameter that shrinks to 6.4 mm, it allows secure fitment on various wiring and cable bundles. Made from flame-retardant, cadmium-free polyvinyl chloride (PVC), this tubing delivers enhanced fire safety and reliable electrical protection in demanding industrial and commercial settings.

This product features a 2:1 shrink ratio, making it easy to apply and ensuring optimal coverage and mechanical strain relief for components and conductors. The tubing is self-extinguishing and offers robust fire protection in compliance with ASTM D2671 standards. Its dielectric strength reaches 15 kV/mm as per IEC243, making it suitable for high-voltage cable insulation needs.

HellermannTyton’s LVR Series heat shrink tubing is compliant with ANSI and UL standards. It exhibits excellent resistance to chemicals and abrasion, supporting installation in environments where durability and long-term reliability are critical. Despite its robust nature, PVC construction ensures relatively easy handling and installation, even in tight spaces or complex cable management setups.

Applications include insulation and protection of power rails, drive shafts, batteries, grips, and other sensitive wiring in automation panels, electrical enclosures, battery systems, and motor drives. Its halogen-free composition supports enhanced environmental safety requirements.

Ideal for industrial automation, panel building, cable sleeving, electrical installation, and maintenance environments. The tubing is supplied in a 5m length reel, offering convenient bulk handling for cable runs and sleeving needs.

Suitable for cable sleeving and insulation in industrial, laboratory, and automation environments. Can be used for protecting and bundling wires, connector joints, and electronic assemblies. Offers enhanced safety for battery packs, motor leads, and electrical rails with robust flame-retardant properties.

Provides reliable mechanical resistance in construction, manufacturing, and facility maintenance applications. Meets ANSI, UL, ASTM and IEC standards - ideal for compliance-driven electrical projects.
