Buying Guide
• Insulation diameter – The insulation diameter depends on the wires you want to join. Choose a connector that can fully encapsulate your wires. Larger diameter connectors for thicker wires and smaller ones for thinner wires.
• Insulation thickness – Thicker insulation provides better insulation and protection. Consider the voltage rating and environmental conditions of use to determine if you need extra thick insulation.
• Voltage rating – Choose connectors that can withstand the voltage of the wires you want to join. Higher voltage connectors for high voltage wires and lower voltage connectors for low voltage wires.
• Temperature resistance – The connector should be rated to withstand the maximum temperatures it will be exposed to. Higher temp resistant connectors for environments with extreme heat.
• Durability – Consider the flexibility, abrasion resistance and cut-through strength of the material as per your application needs. Stiffer or softer tubings depending on flexibility needs.
• Coloring – Heat shrink connectors come in different colors like black, red, yellow, etc. Choose a color that matches or contrasts your wires for easy identification.
• Material – Popular materials include Polyolefin, Polyvinylchloride (PVC), Fluoropolymer (FEP, PTFE), Silicone rubber, Etc. The material depends on properties like flexibility, temperature, chemical resistance, etc. needed for your application.
• Brand – Like for any product, reputed and high-quality brands generally offer better durability, reliability and consistency. Check reviews to determine top brands for heat shrink tubing and connectors.
• Certifications (optional) – Look for certifications like UL, RoHS, etc. depending on usage environment and industry standards. These ensure the product meets safety and quality standards.
