BullDog Hose Mainline

Mainline™

Mainline™ is a flexible lay-flat hose with a wide diameter which ensures that your operation moves liquid as efficiently as possible. Featuring a unique “through-the-weave” one-piece construction comprising a circular woven high tenacity polyester reinforcement totally encapsulated in a tough elastomeric polyurethane cover and lining. Designed for long life and maintenance free service – in even the toughest field conditions. High flexibility and kink resistance allows natural ground contours to be followed without putting stress on the line and eliminates expensive path cutting work.

Features
  • Designed for long life and maintenance free service in even the harshest environments. Tough and durable with exceptional resistance to abrasion and cutting for use on a wide variety of ground conditions. No corrosion or scaling. Resistant to fuels, chemicals, UV, ozone, weathering, hydrolysis, and microbiological attack
  • A low-pressure loss for efficient pumping. Swells up to 10% above uncharged diameter at maximum operating pressure enabling more water to be pumped
  • Features a unique “through-the-weave” one-piece construction comprising a circular woven high tenacity polyester reinforcement totally 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 eliminates expensive path cutting work. Fewer joints and faster connections mean reduced labor and equipment costs
  • Long-term storage in coiled configurations will have minimal impact on hose life
  • Available with bonding wires, conforming to MIL-PRF-370 Type C, are fitted to allow couplings to be electrically bonded when transferring fuels
  • A wide range of couplings, manifolds, and hardware available for connecting the hose to additional segments, fluid supplies, or auxiliary hardware
