WILDCATTER® Multipurpose
Fracking Suction Hose
Supersedes Series 7330 & SW333

Series 7331/7331XT is a high pressure oilfield stimulation/fracking suction and 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 provides an extended service life in multiple applications, and incorporates a wire helix that provides full suction capability, kink resistance, flexibility for ease of handling and a path to conduct a static electrical charge to ground. The cover is resistant to abrasion, oil and weathering.

Series 7331XT features a layer of ultra high molecular weight polyethylene (UHMWPE) bonded to the cover for extreme abrasion resistance and service life.

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