While rigid plastic, threaded caps can be the ideal solution for certain applications, many people opt for our line of flexible vinyl Short Caps instead. In short, plastic threaded caps need to be screwed in and out in what is typically a rather labor intensive activity. For greater speed and flexibility, many opt for our line of vinyl Short Caps as an alternative.

  • Vinyl caps are also typically easier to install and do not crack, split, or shred in the way that many polyethylene caps will over time.
  • Unlike Threaded Caps, vinyl Short Caps can be made in virtually any length one desires with no additional tooling charges. 
  • Short Caps can be manufactured in wide variety of colors and materials without extensive lead times.
