Panduit HSTT Dry-Shrink™ Heat Shrink Tubing, Black

The Panduit HSTT Dry-Shrink™ Heat Shrink Tubing is a flame-retardant, cross-linked polyolefin tubing that shrinks around wires, connectors, joints, and terminals when heated, protecting them from abrasion in indoor, dry locations. This family is available in diameters ranging from 1" through 375", letting installers match tubing to the exact wire bundle, splice, or terminal size required for the job. Every size in the HSTT line shares a 2:1 shrink ratio, a shrink temperature of 194°F (90°C), and an operating temperature range of -67°F to 275°F (-55°C to 135°C). Built to UL E122770 and Mil Spec AMS-DTL-23053/5 Class 1 standards, HSTT tubing delivers dependable insulation and mechanical protection for professional wire and cable installations across commercial and industrial environments.

Key Features

  • Size Range: Available in diameters from 1" through 375" to accommodate a wide range of wire bundles, connectors, and terminal sizes.
  • Durable Construction: Flame-retardant, cross-linked polyolefin material resists abrasion, chemicals, and heat damage.
  • Shrink Ratio: Consistent 2:1 shrink ratio with a shrink temperature of 194°F (90°C) across the entire size range for a snug, protective fit around wires, connectors, and terminals.
  • Operating Temperature Range: -67°F to 275°F (-55°C to 135°C) for reliable performance across demanding indoor conditions.

Panduit HSTT38-C – Frequently Asked Questions

1) What size wire or connector will Panduit HSTT heat shrink tubing cover, and which roll should I order?
Panduit Dry-Shrink HSTT is sold by expanded inside diameter, and the size you pick has to slide over the largest point on the joint (usually the connector barrel or the lug), not just the wire. Four rolls are offered: HSTT38-C, HSTT50-C, HSTT75-C and HSTT100-C. With a 2:1 shrink ratio, each one recovers to half its supplied diameter, so a roll will not grip anything smaller than half its expanded size. Every roll is 100 feet long and ships as one roll.
2) What temperature does HSTT tubing need to shrink, and can I use a heat gun?
Recovery starts at 194 degrees F (90 degrees C), which is well within the range of a standard electrical heat gun. Keep the gun moving along the length so the polyolefin recovers evenly instead of scorching in one spot.
3) Can Panduit HSTT heat shrink be used outdoors or in a wet location?
No. Dry-Shrink HSTT is for indoor, dry locations, protecting wires, connectors, joints and terminals from abrasion. It is not adhesive lined, so there is no internal sealant to block moisture from tracking under the tubing. For a buried splice, a wet well, or an exterior run, use an adhesive lined (dual wall) tubing or a proper sealed splice kit instead.
4) Is this heat shrink flame retardant and UL listed for a commercial job?
The HSTT tubing is flame retardant cross-linked polyolefin, UL Listed under E122770, and built to Mil Spec AMS-DTL-23053/5 Class 1. That combination is what a facility or government spec usually calls out for insulating and protecting terminations, and it is RoHS compliant with no lead or mercury content and no Prop 65 cancer warning.
5) What temperature range can HSTT tubing handle once it is installed?
Installed, the tubing holds up from -67 to 275 degrees F (-55 to 135 degrees C). That covers unheated warehouses and walk-in cooler wiring at the low end and motor, ballast, and panel terminations at the high end.
6) Is Panduit HSTT sold by the roll or in pre-cut pieces?
It comes as continuous 100 foot roll, one roll per order, so you cut your own lengths on the bench or in the field. Minimum order is one roll. Continuous stock is the practical choice when you are terminating a panel or a harness and need dozens of different cut lengths off the same diameter.
7) How much length do I lose when the tubing shrinks?
Plan the cut with the recovered diameter in mind rather than the length. HSTT is a 2:1 diameter shrink product, so the tubing closes down radially onto the connector; cut a piece that overlaps the insulation on both sides of the joint so nothing is left exposed after recovery at 194 degrees F.
