PRODUCT PARAMETERS

High-expansion silicone rubber cold shrink tubing is made from specially formulated silicone rubber, featuring a large shrinkage ratio, excellent physical and mechanical properties, and puncture resistance. It is suitable for waterproof and moisture-proof sealing of communication and flexible hose connections, insulation sealing of wire and cable connections, and insulation protection of other types of connectors.

Product Features

• Continuous operating temperature: -60℃~200℃

• Expansion ratio up to approximately 4 times, suitable for connections and seals of different diameters, featuring strong resilience, high constant pressure resistance, long-term moisture and water resistance.

• Weather resistance, sun exposure resistance, ozone aging resistance, wind resistance, and salt spray corrosion resistance.

• Extremely high expansion strength; after a small cut is made with a knife, the cut will not continue to expand.

• No heating or special tools required; no hot melt adhesive or tape is needed to reinforce the seal at the joint.

• Colors: Black, Gray
