300-30953 Description

Short technical summary and product information.

The HellermannTyton 300-30953 is a general-purpose heat shrink tubing from the HIS-PACK family, designed for reliable electrical insulation and protection against corrosion and mechanical stress. It features a 2:1 shrink ratio, with a supplied inner diameter of 0.187" (4.75mm) recovering to 0.094" (2.38mm). The recovered wall thickness is 0.023" (0.58mm).

 

Made from cross-linked polyolefin (PO-X), this clear tubing operates over a temperature range of -55°C to +135°C and requires a minimum shrink temperature of 120°C. It provides a dielectric strength of 20 kV/mm per ASTM D2671 and carries a UL224 VW-1 flammability rating (note: datasheet indicates VW-1 except clear; apply cautiously). The tubing is supplied on a reel, with a typical package length of 10 meters.

 

This tubing is suitable for a wide range of applications requiring insulation, strain relief, and environmental sealing. Its flexibility and corrosion-resistant properties make it ideal for use in electrical enclosures, wire harnesses, and general maintenance tasks.
