The HTS-3000 Heavy Wall Heat Shrink Tube is a high-performance, military-grade insulating solution engineered for demanding electrical and aerospace applications. Designed to meet the rigorous requirements of MIL-DTL-23053/5 Type II, this 3:1 shrink tubing delivers exceptional mechanical protection, environmental sealing, and dielectric integrity. With an ultra-durable 0.8mm wall thickness and a wide recoverable inner diameter range (3.2mm–25.4mm), the HTS-3000 offers superior abrasion resistance, crush strength, and long-term reliability—making it ideal for harsh-condition wiring harnesses, cable splices, and connector overmolding.
Its precise 3:1 shrink ratio ensures tight, conformal fit over irregular geometries and bundled assemblies without voids or wrinkles, while the cross-linked polyolefin base provides excellent flame retardancy (UL 224 VW-1), fluid resistance, and operating temperature stability from –55°C to +135°C. As a certified heavy wall heat shrink tube, HTS-3000 exceeds commercial-grade alternatives in both durability and compliance assurance.
