Flexible Heat Shrink Tubing for Gas Pipelines is manufactured from radiation‑crosslinked polyolefin material. With soft and flexible texture and stable shrinkage performance, it delivers outstanding physical, chemical and electrical insulation properties. Featuring great aging‑resistance and abrasion‑resistance, it can withstand daily friction and impact. It is designed to provide thermal insulation and protection for household gas connecting hoses, isolating external high‑temperature heat source to avoid overheating damage, slow down hose aging and reduce potential safety risks. Widely used for protective sleeving on connection hoses of household gas stoves and gas water heaters. Easy for installation, it closely conforms to hose surface after heat shrinking, serving as an ideal supporting protective component for domestic gas pipeline systems.
