The Kable Kontrol® 3:1 Heavy Wall Adhesive Lined Heat Shrink Tubing is built for applications where maximum protection and a fully sealed connection are essential. Designed with a rugged polyolefin outer layer and an inner EVA adhesive lining, this tubing delivers a dependable moisture-tight bond that shields electrical splices, joints, and terminations from harsh environmental conditions. Once heated, the 3:1 shrink ratio allows the tubing to conform tightly around oversized connectors and uneven shapes, creating a secure and long-lasting seal. Its heavy-wall construction provides strong resistance against abrasion, impact, and mechanical wear, while also offering excellent electrical insulation. With an operating range of –45°C to 125°C (-49°F to 257°F) and a low minimum shrink temperature of 125℃ (257°F), it performs reliably in both indoor and outdoor environments. Supplied in convenient 4-foot sticks and compliant with RoHS standards, this tubing offers a durable, professional-grade solution for protecting and sealing electrical connections.
