Panduit Dry-Shrink™ HSTT Series Heat Shrink Tubing, Flame-Retardant Polyolefin

The Panduit Dry-Shrink™ HSTT Series is a family of thin-wall heat shrink tubing built from green, cross-linked polyolefin, available in .25 in. (6.4 mm) and .38 in. (9.5 mm) diameters and supplied 100 ft. (30.5m) per reel. Every diameter in the HSTT Series shares a 2:1 shrink ratio, flame-retardant resistance properties, and a shrink temperature of 194°F (90°C) for fast, reliable application in dry-location electrical installations. The tubing carries UL Recognized, CSA Approved, and MIL SPEC listings, giving electrical professionals a code-compliant option for insulation and mechanical protection across commercial and industrial wiring projects.

Key Features

  • Diameter Range: Available in .25 in. (6.4 mm) and .38 in. (9.5 mm) thin-wall diameters to match a range of wire and cable bundling needs.
  • Durable Construction: Green, cross-linked polyolefin material with flame-retardant resistance properties.
  • Shrink Ratio: 2:1 shrink ratio activated at a shrink temperature of 194°F (90°C) for fast, reliable application across the entire HSTT Series.
  • Operating Temperature Range: Rated from -67°F (-55°C) minimum to 275°F (135°C) maximum for wide environmental durability.
  • Wall Thickness: 0.025 in. (0.6mm) nominal recovered wall thickness for a low-profile finish.
  • Application: Intended for dry-location use in commercial and industrial electrical systems.
  • Packaging: Supplied on a 100 ft. (30.5m) reel for continuous-length installations.

Panduit HSTT25-C5 – Frequently Asked Questions

1) What temperature does HSTT tubing need to shrink, and can I use a heat gun?
Recovery starts at 194 F (90 C), which is well within the range of any standard electrical heat gun. Keep the gun moving along the tube so the polyolefin recovers evenly rather than scorching in one spot. Once installed, the tubing holds service from -67 F (-55 C) up to 275 F (135 C).
2) Can I use this Panduit heat shrink tubing on a direct burial or outdoor wet splice?
No. The HSTT Series is rated for dry locations only and it is not adhesive lined, so there is no sealant wall to block moisture at the ends. For a buried, submerged, or weather exposed splice you need an adhesive lined (dual wall) tubing instead. HSTT belongs in panels, enclosures, conduit runs, and interior harnesses.
3) Is Panduit HSTT tubing flame retardant and does it carry any listings?
The polyolefin is cross-linked and flame retardant, and the HSTT Series carries UL Recognized, CSA Approved, and MIL SPEC listings. It is also RoHS compliant. That combination is what most industrial and commercial specs are looking for on panel and enclosure wiring.
4) How is Panduit HSTT heat shrink sold, by the foot or on a reel?
It ships on a continuous 100 ft. (30.5 m) reel, and the reel is the unit of sale, with a minimum order of one roll. Cut your own lengths off the spool rather than buying pre-cut sticks. A standard carton holds 10 reels if you are stocking a truck or a shop.
5) Which Panduit part number do I order for 3/8 inch heat shrink?
Order HSTT38-C5 for the .38 in. (9.5 mm) diameter and HSTT25-C5 for the .25 in. (6.4 mm). Both are green flame-retardant polyolefin, 2:1 ratio, on 100 ft. reels; the only difference between them is the expanded diameter.
6) Why is this heat shrink green, and can I use color for circuit identification?
The HSTT reels are green through the body of the material, not a surface coating, so the color stays after recovery. Electricians commonly use colored thin-wall shrink to code grounds or to keep circuits straight inside a panel. If your marking scheme needs a different color, this reel will not give it to you, only green.
7) Is the 0.025 inch wall on HSTT thick enough for mechanical protection, or just insulation?
At 0.025 in. (0.6 mm) nominal recovered wall this is a thin-wall product. It gives you dielectric insulation, strain relief at a termination, and abrasion cover on a bundle. For heavy impact or crush protection on a cable pulled through rough structure, a heavy-wall tubing or a sleeve is the better call.
8) Does this Panduit tubing contain lead or mercury, or need a Prop 65 warning?
No lead, no mercury, and no California Proposition 65 cancer warning applies. It is RoHS compliant and is not flagged as hazardous material for shipping. Country of origin is China. That covers the usual submittal questions on a government or healthcare job.
