What this product is

HellermannTyton 300-73608 is a thin-wall heat shrink tubing supplied on a 200 ft reel. It has a 2:1 shrink ratio with a .75 inch supplied diameter that recovers to .38 inch. The black polyolefin material is cross-linked and self-extinguishing for electrical insulation and wire protection.

Check before ordering

Verify that the .75 inch supplied diameter fits over your largest wire bundle or connector before shrinking. Confirm the operating temperature range of -67 °F to +257 °F (-55 °C to +125 °C) matches the environment where the tubing will be installed. Ensure the 600 V voltage rating meets the circuit requirements.

Who this suits and who it does not

This tubing suits installers needing a continuous 200 ft length of UL 224 and CSA recognised sleeving for general harnessing. It is not for buyers who require an adhesive lining for environmental sealing. It is not for applications needing a halogen-free material. It is not for projects where a higher shrink ratio or thicker wall is specified.

Questions about this item

What does the 200 ft reel contain and is anything else needed to use it?

The reel supplies 200 ft of thin-wall PO-X heat-shrink tubing with a 2:1 shrink ratio, supplied diameter .75 in and recovered diameter .38 in. A heat gun or similar heat source is required to shrink the tubing; no adhesive liner or extra components are included.

How do I choose between the listed diameters and lengths for this part?

This specific part number 300-73608 is a single variant: 3/4 in nominal diameter, 0.031 in wall thickness, black, 200 ft per reel. Other diameters or lengths carry different part numbers, so select the variant that matches the cable bundle size you need to cover.

What does the 2:1 shrink ratio mean when the tubing is on a real cable?

When heated, the tubing shrinks to half its supplied diameter — from .75 in down to .38 in — conforming tightly around the cable. The operating range of -67 °F to +257 °F and self-extinguishing PO-X material maintain the seal in harsh environments.
