RHINO

About RHINO

RHINO is a brand of standard heat shrink tubing, primarily recognized for its Color-Coded Shrink Tubing (RCT) series. The product line is designed for electrical insulation, mechanical protection, and color-coding of wires and cables in industrial, commercial, and utility applications. RHINO tubing is manufactured from cross-linked polyolefin, a material that provides a balance of flexibility, durability, and thermal stability. The tubing is rated for a continuous operating temperature range typically from -55°C to +135°C, with a shrink temperature of approximately +90°C to +125°C. All RHINO Color-Coded Shrink Tubing products feature a 2:1 shrink ratio, meaning the tubing reduces to half its original inner diameter when heated. This ratio is standard for general-purpose applications, allowing the tubing to conform snugly over connectors, terminals, and cable splices. The tubing is available in multiple colors—including Clear, Yellow, Orange, Blue, and White—to facilitate wire identification and organization in complex wiring systems. Inner diameters before shrinking range from 1 inch to 4 inches, with corresponding after-shrink diameters from 0.5 inch to 2 inches. Each piece is supplied in 4-foot lengths, providing sufficient material for multiple installations or large-diameter cable bundles. RHINO tubing meets basic flame-retardant requirements, typically rated VW-1 or equivalent, and is RoHS compliant, ensuring it is free from restricted hazardous substances. The tubing is suitable for use in environments where moderate abrasion resistance and electrical insulation are required, such as in control panels, switchgear, motor leads, and cable harnesses. 3G Electric stocks a range of RHINO Color-Coded Shrink Tubing SKUs, covering the most common sizes and colors. This allows procurement specialists and maintenance managers to source tubing for routine repairs, new installations, or inventory replenishment without minimum order constraints. The tubing is packaged in individual 4-foot sticks, making it easy to handle and store. For applications requiring larger diameters or specific color codes, the RCT series provides a consistent specification across all sizes. 3G Electric supports the RHINO line with logistics for global shipment, enabling engineers and buyers to obtain standard heat shrink tubing for projects in any region. The product is a practical choice for general-purpose wire and cable protection where certified performance to UL or CSA standards is not explicitly required but where reliable, repeatable shrink characteristics are expected.
