WILDCATTER® Multipurpose Fracking Hose
Supersedes Series 7309, 7311 & 7311XT

Series 7311N/7311NXT is a high pressure oilfield stimulation/fracking discharge hose designed to handle oil and refined fuels such as biodiesel (to B20 in dedicated service), diesel, ethanol and gasoline, as well as brine, mild chemicals, fracking fluids, drilling mud, petroleum waste, slurries and water. The heavy duty multipurpose hose construction helps to extend service life in multiple applications, and incorporates dual static wires that provide a path to conduct an electrical charge to ground. The cover is resistant to abrasion, oil and weathering.

Series 7311NXT features a layer of ultra high molecular weight polyethylene (UHMWPE) bonded to the cover for extreme abrasion resistance and service life.

Series 7311N and 7311NXT are available in optional 200-foot continuous lengths through 4" ID.

NOTE:
• Refer to Technical Resources>Guides & Tables for fuel compatibility and service conditions.
