Note: This is a variation of Glastic UTR Composite Tubing (350ºF Economical Round, Square, and Rectangular Tubing).

  • UL Recognized
  • Highly Flame-Resistant
  • Arc-and Track-Resistant
  • Uncommon Dimensional Stability
  • Strong & Durable, yet Easily Cut and Chamfered
  • Cost-Effective

Glastic® Grade UTR Pultruded Tubing is a fiberglass-reinforced thermoset polyester tube. It meets the requirements of NEMA grade GPO-3, as well as being recognized by Underwriters Laboratories®.
Highly flame-, arc-, and track-resistant, Glastic UTR pultruded tubing provides reliability in a wide range of applications. The product exhibits exceptional dimensional stability and is impervious to high humidity or immersion. Also, because it is constructed of a reinforced plasticell nameomposite, it is electrically non-conductive.
This tubing has a UL index rating of 130ºC electrical and 160ºC mechanical. Its burst strength is 1,200 to 1,400 psi, yet it is easily chamfered and cut with carbide or diamond saws.
