The 5053144070 is a flexible, flame-retardant polyolefin heat-shrinkable tubing from the RNF-100 series, designed for general-purpose insulation and mechanical protection. It features a 2:1 shrink ratio and operates over a temperature range of -55°C to 135°C. The tubing requires a minimum shrink temperature of 95°C and fully recovers at 121°C, allowing it to conform to irregular shapes. It provides superior abrasion and solvent resistance and is rated for 600V at 125°C per UL and CSA standards. This tubing is widely used for insulating wire terminations, providing strain relief, jacketing wire bundles, and color-coding components.
