TZRS-DR150(2X)
VOLSUN
TZRS-DR150(2X) diesel resistant elastomeric heat shrink tubing is engineered for electrical insulation and mechanical protection of cables, wire harnesses, terminals, branch joints and connectors exposed to fuels, oils and high-temperature environments. The tubing is manufactured from radiation-modified polymer elastomer and offers a combination of flexibility, flame retardancy, long-term heat resistance and fluid resistance.
It is suitable for use in military vehicles, high-speed railway vehicles, marine equipment and commercial cable assemblies where protection against diesel, aviation fuel and high-temperature fluids is required. The product has a 2:1 shrink ratio, operates from -75°C to 150°C and complies with RoHS environmental requirements.

How to Select the Right Size
Choose a supplied ID that is large enough to slide over the cable, terminal or joint before shrinking. After heating, the recovered ID should be smaller than or close to the outside diameter of the covered object to ensure a tight fit. Refer to the dimensions table for supplied ID, recovered ID and wall thickness.
Installation Guidelines
Apply heat evenly around the tubing until it fully conforms to the cable, terminal or joint. The recommended shrinking temperature range is 110°C to 220°C. Avoid overheating or applying direct flame unless approved by the installation procedure.
Compliance and Test Methods
RoHS compliant
Tensile strength and elongation tested according to ASTM D2671
Dielectric strength tested according to IEC 60243
Flame retardancy tested according to ASTM D2671 Procedure B
