The Runlin Cold Shrink Tubing is a factory‑expanded sleeve made from EPDM rubber, designed for telecom and power cable sealing. Each sleeve is pre‑mounted on a removable plastic core that expands the tube for field installation, allowing the tube to shrink around the conductor without heat. The product is supplied in bulk kits for large‑scale infrastructure projects and is compatible with GSM, 4G LTE and 5G NR base‑station equipment. The tubing is marketed as a moisture‑tight seal for coaxial and RF cable assemblies.
EPDM provides excellent weather, ozone and ageing resistance, and operates over a temperature range typically from - 50 °C to +150 °C. Cold‑shrink technology offers a shrink ratio of about 2 : 1, covering inner diameters from 4 mm to 30 mm and achieving outer diameters after shrink of 6 mm to 45 mm, which is standard for telecom sealing. The material complies with IEC 60512 for shrinkable sleeves and meets IEC 60228 conductor standards when used on coaxial cables. Compared with heat‑shrink tubing, cold‑shrink retains flexibility over a long service life and resists cracking under thermal cycling.
The tubing is used for sealing coaxial and RF cable joints, protecting medium‑voltage and low‑voltage power cables, and insulating secondary splices in both indoor and outdoor environments. Buyers typically order in bulk rolls or kits, with shipment arranged on a CIF or FOB basis depending on the contract; exact MOQ, Incoterms and payment terms must be verified with Fast Industrial And Trading Limited. Because the supplier’s response rate is currently 0 %, importers should request lead‑time estimates and confirm any required certifications such as RoHS. The product is suitable for harsh environments, offering long‑term moisture protection.

Before confirming a purchase, verify the exact EPDM formulation, operating temperature range and any compliance certificates such as IEC 60512 or RoHS that may be required for your market. Request a material data sheet or a recent test report to ensure the tubing meets your project's specifications.
Logistics for cold‑shrink tubing from China often involve sea freight on a CIF or FOB basis. Because the supplier’s response rate is currently zero, ask for confirmed lead‑time estimates, agreed Incoterms and payment terms such as T/T or LC before finalising the contract. Clarify the packaging size and weight to avoid freight calculation errors.
Arrange a third‑party inspection at the point of loading or upon arrival to check material integrity, dimensions and compliance with stated standards. Request documentation including a test report, packing list and bill of lading. Incorporate these quality‑assurance steps into your purchase agreement to protect against non‑conforming deliveries.
