Co-Extruded Tubing

Envir-A-Line™ XX is commonly used for many gases and hydrocarbons. has a unique co-extruded construction, incorporating a highly inert Hytrel® inner-liner that exhibits excellent dielectric properties and provides a superior gas and moisture barrier. Its moisture permeability is similar to poly-ether based urethanes. The product’s outer shell is comprised of a permeable photo-opaque black PVC, so the product can be repeatedly autoclaved without the two materials separating.
Used widely in the welding industry because of its superior barrier and dielectric characteristics, Hytrel® contains no plasticizers and does not outgas. The consistant quality and performance of Envir-A-Line™ XX is due partly to the industry leading thickness of our Hytrel® inner-liner thickness. Envir-A-Line is also commonly used in the beverage industry. It is FDA approved and compliant with NSF51 standards for potable water. *Also available with photo opaque hygienic white outer shell, high pressure outer braiding for higher pressures.
