BullDog Hose Mainline lay flat

Mainline™

Lay-Flat Agricultural Hose

Mainline™ is a flexible lay-flat drag hose with a large diameter to ensure that your operation moves as smooth and efficiently as possible. Mainline features a unique through-the-weave one-piece construction—comprising a circular-woven high-tenacity polyester reinforcement completely encapsulated in a tough elastomeric polyurethane cover and lining—designed for long life and maintenance-free service, even in the toughest field conditions. High flexibility and kink resistance allows natural ground contours to be followed without putting stress on the line and eliminating costly path cutting work.

Features
    • Low pressure loss for efficient pumping. Swells up to 10% above uncharged diameter at maximum operating pressure.
    • Features a unique “through-the-weave” one-piece construction—comprising a circular-woven high-tenacity polyester reinforcement completely encapsulated in a tough elastomeric polyurethane cover and lining.
    • Long continuous lengths can be quickly deployed and retrieved using a wide variety of systems including light-duty trailers, flaking boxes, and power-driven reels. High flexibility and kink resistance allows natural ground contours to be followed without putting stress on the pipeline and eliminating costly path cutting work. Fewer joints and faster connections mean reduced labor and equipment costs.
    • Available with bonding wires—conforming to MIL-PRF-370 Type C—fitted to allow couplings to be electrically bonded when transferring fuels
    • A wide range of couplings, manifolds, and hardware are available for connecting additional segments, fluid supplies, or auxiliary hardware.
