MC-331 Transport Trailers


From Start to Finish

Engineered for Performance –

Polar’s comprehensive line of MC-331 pressurized trailers brings together the full complement of engineering design and performance features you’d expect from the industry’s leading transport innovators. Built on the Polar Tank Trailer / JARCO heritage of quality, every unit is backed by the nation’s largest propane parts and service network, for ongoing support and lasting value you can count on.


Distinctive Polar Features –


  1. Powder Coated Barrel for Longer Lasting Finish Standard on all Polar MC-331 trailers, powder coat over zinc undercoating provides:
    • Uniform finish stays brighter longer for lower overall maintenance.
    • More durable than liquid paints, resists corrosion, chemicals, chipping and scratching.
    • Nicks and scars are isolated to the point of impact for easy repair.
  2. Powder Coated Stainless Steel Undercarriage for Longest Trailer Life
    • Suspension and Undercarriage
    • Pump and Pipe Load Rack
    • Landing Gear
    • Fifth Wheel Plate Frame
    • Fender Supports
  3. Stainless Steel Piping, Valves and Hardware for Easy Maintenance All-weld stainless steel piping reduces the chance of leaks and maintains the unit’s appearance over time. All non-torque-sensitive bolts and U-bolts, and even the mounting studs for the internal valves are also stainless steel, ensuring easy maintenance for year to come.
  4. Stainless Steel Hydraulics and Blowdown Lines All welded, stainless steel tubing, pressure tested at two times operating pressures. Stauff (need R enclosed in circle to designate trademark registered name) clamps hold lines secure versus standard U-bolts which loosen over time.
  5. Hendrickson Axles Hendrickson Air Ride Suspension Axles available in soft coat or painted and rock guarded for superior chip resistance and corrosion control.
