Wire Size Chart Generally, the largest tube that shrinks down tightly onto an object should be chosen. This allows the heat shrink tubing maximum stress relief and this will yield the longest service life. Example: A multi-conductor cable needs to be covered with HSTT Type Dry-Shrink ™ Heat Shrink. The area to be covered has a measured outside diameter of .700" (17.8mm). The two possibilities are HSTT75-48-5 and HSTT100-48-5. Approximate Wire Outside Diameter In.

The wire is rated 75°C wet or dry. THWN wire suitable for exposure to mineral oil and to liquid gasoline and gasoline vapors at ordinary ambient temperature is marked “Gasoline and Oil Resistant I” if suitable for exposure to mineral oil at 60°C, or “Gasoline and Oil Resistant II” if the compound is suitable for exposure to mineral oil at 75°C. Gasolineresistant wire has been tested at 23°C when immersed in gasoline. It is considered inherently resistant to gasoline vapors within the limits of the temperature rating. HSTT75-48-5 HSTT100-48-5 Expanded I.D In. (mm) Recovered I.D. In. (mm) .750 (19.1) 1.00 (25.4) .375 (9.5) .500 (12.7) The proper choice is HSTT100-48-5 since the tube will recover more than HSTT75-48-5. The HSTT75-48-5 will fit over the .700 inch (17.8mm) outside diameter; however, this is not the proper choice since it is smaller than the HSTT100-48-5. In general, heat shrink should recover at least 10% – 20% to reduce stress and yield the longest service life and thicker walls, resulting in thicker insulation, more abrasion protection, and more strain relief.

Pick the right diameter. (See Wire Size Chart on page 5) Consider the overlap between the tube and the cable insulation Heat evenly around the tube If using a flame, use a diffuser and keep it moving; start further away from the tube and move closer gradually If it’s adhesive lined product, the adhesive will be pushed away from the recovery starting point; in general, start recovering at the center and work toward each end 2. What’s the significance of a material being cross linked? The majority of heat shrink is made from cross linked materials. Cross linked materials do not melt and flow; they soften and become rubbery but still hold their basic shape. The main benefit is improved thermal, physical and chemical resistance. 3. Why is shrink temperature important? A tube with a lower shrink temperature will generally shrink faster. Products with higher shrink temperatures generally have higher performance. With any heat shrink tube, you can increase the shrink speed by using hotter temperatures, within reason. Be sure to consider the heat resistance of components under or around the heat shrink. D R Y 4. Can the tube be damaged by overheating and what are the signs of overheating? Excessive temperatures and long exposure times cause damage faster. Most tubes will withstand 200°C to 250°C for a couple of hours without significant damage. Overheating can be difficult to detect since damage may not be obvious. If using a torch, use a flame diffuser, keep the flame at a proper distance, and keep the flame moving to apply heat gradually. Heat guns are easier to work with but can still cause damage. Charring, blistering, or cracking of the surface is a definite sign of overheating and damage. 5. How does operating temperature range relate to shrink temperature? If the operating temperature is above the shrink temperature of the tube, the tube will be in a soft rubbery state, and it will have lower mechanical properties and abrasion resistance. 7. What’s the maximum voltage at which I can use Panduit heat shrink? Unless noted otherwise, all the products have a 600V AC rating. They are “low voltage” products. Per NEMA, Low Voltage is 600V or less; Medium Voltage is 2,400 to 69,000 V; and High Voltage is 115k to 230kV.

THWN wire suitable for exposure to mineral oil and to liquid gasoline and gasoline vapors at ordinary ambient temperature is marked “Gasoline and Oil Resistant I” if suitable for exposure to mineral oil at 60°C, or “Gasoline and Oil Resistant II” if the compound is suitable for exposure to mineral oil at 75°C. Gasolineresistant wire has been tested at 23°C when immersed in gasoline. It is considered inherently resistant to gasoline vapors within the limits of the temperature rating. HSTT75-48-5 HSTT100-48-5 Expanded I.D In. (mm) Recovered I.D. In. (mm) .750 (19.1) 1.00 (25.4) .375 (9.5) .500 (12.7) The proper choice is HSTT100-48-5 since the tube will recover more than HSTT75-48-5. The HSTT75-48-5 will fit over the .700 inch (17.8mm) outside diameter; however, this is not the proper choice since it is smaller than the HSTT100-48-5. In general, heat shrink should recover at least 10% – 20% to reduce stress and yield the longest service life and thicker walls, resulting in thicker insulation, more abrasion protection, and more strain relief.

Part Number THWN – Indicates a single conductor having flame-retardant, moisture and heat-resistant thermoplastic insulation with a jacket of extruded nylon or equivalent material. The wire is rated 75°C wet or dry. THWN wire suitable for exposure to mineral oil and to liquid gasoline and gasoline vapors at ordinary ambient temperature is marked “Gasoline and Oil Resistant I” if suitable for exposure to mineral oil at 60°C, or “Gasoline and Oil Resistant II” if the compound is suitable for exposure to mineral oil at 75°C. Gasolineresistant wire has been tested at 23°C when immersed in gasoline. It is considered inherently resistant to gasoline vapors within the limits of the temperature rating. HSTT75-48-5 HSTT100-48-5 Expanded I.D In. (mm) Recovered I.D. In. (mm) .750 (19.1) 1.00 (25.4) .375 (9.5) .500 (12.7) The proper choice is HSTT100-48-5 since the tube will recover more than HSTT75-48-5. The HSTT75-48-5 will fit over the .700 inch (17.8mm) outside diameter; however, this is not the proper choice since it is smaller than the HSTT100-48-5. In general, heat shrink should recover at least 10% – 20% to reduce stress and yield the longest service life and thicker walls, resulting in thicker insulation, more abrasion protection, and more strain relief.
