Notes:
1. The hi-ratio tubing is heat-shrinkable and has expansion ratios as high as 6:1.
2. “X” indicates reference-recovered length in inches (e.g. for 3.0-inch length: HRHT-2/3).
The tolerance shall be +/- 10% of the specified recovered length.
3. The tubing is UL recognized in sizes 1 through 4 only. The reference number is E85381(R).
Material: -152, heat shrinkable, crosslinked flexible polyolefin.
Standard factory applied hot melt adhesive is /97 or /42, as required.
