Pigtails used on your transfilling system, if maintained properly, can last for years. Everytime you fill, you should visually inspect your pigtails for damage. If there are kinks or weak points, such as from folding, the the pigtails could snap from the high pressure and become dangerous to you or others.

Additionally, Applied recommends that your pigtails used with transfilling systems be tested annually to ensure that they are safe for use. You should also test them if you suspect there might be a problem with them.  

Perform the following inspections on pigtails. If the pigtail fails any inspection it should be removed from service and either repaired or replaced. Don’t forget to wear proper safety equipment when testing high pressure equipment.   

   * Visually inspect pigtails for corrosion, kinked areas, crimps, or any other external damage.
   * Spray the pigtail and its connection point with an oxygen compatible leak testing solution. 
     The solution will form large bubbles if a leak is present.
   * Conduct pressure testing on the pigtail by slowly pressurizing the pigtail and checking for damage.
   * Inspect the threads of the connection. If the threads are damaged, the connection should be replaced

Instead of performing this testing in house, you can have Applied technicians perform the testing for you, just send us your pigtails, along with our pigtail inspection form.
