HST Splice Calculator
Eurotech HST Splice Calculator
Use this form to calculate the overall size of your splice and to choose the best HST size. For a single-sided splice, use only the Side A column.

Bundle Cross-Sectional Areas
Use the box 4 numbers and the graph in Figure 6 of the Eurotech Heat-Shrink Tube Installation Guidelines to review the sealability of your splice design.
HST Selection by Bundle Diameters
Use the box 5 numbers to select your HST size from the appropriate Eurotech drawing or data sheet.
Divide the smaller box 5 side by the larger side. Use this number to estimate the recommended Shrink Ratio.
Chose an IDe (expanded) that fits over the larger side.
Chose an IDr (recovered) that is less than the smaller side.
1.00 to 0.50 = 2:1
0.49 to 0.33 = 3:1
0.32 to 0.24 = 4:1
0.49 to 0.33 = 3:1
