Poly Tubing

At Midland we offer a high quality UV stabilized 4mil & 6mil ventilation poly tubing which also comes with a hole punched option.

Single Line Punching is the most widely used system for heating and ventilation. Our tubing is punched to your specifications to suit all known fan systems. With many available hole sizes, we offer a range of punching and spacing requirements, so ultimately  the air flow can be directed where it’s needed most. Convection Tubing is available in the following options:

  • Diameters: 6″, 8″, 10″, 12″, 14″, 16″, 18″, 20″, 24″, 25″, 30″ and 37″
  • Hole sizes: 0.5″, 1″, 1.5″, 2″, 2.5″ and 3″
  • Hole Positioning: 4/8 (standard), 5/7, and 3/9. The numbers refer to the numbers on a clock (i.e. 4/8 means holes in the 4 o’clock and 8 o’clock positions).
  • Distance Between Holes: 12″, 18″, and 24″ (18″ and 24″ are the most common)
