Actual operational experience with the spheres will allow more accurate sizing for any given pipeline or meter power.

  • Urethane – 1% larger than pipe ID
  • All other compounds – 2% larger than pipe ID
  • Remove quick coupling from pressure hose end and thread it into filling adapter.
  • Fill reservoir on pump with suggested liquid and operate pump until all air is removed from the pump and the hose before connecting filling adapter to sphere.
  • Connect hose filling adapter and proceed to size sphere to proper diameter.
  • After reaching proper size, pressure may be relieved from filler hose with small hand valve.
  • Remove filling adapter from sphere valve.
  • Firmly replace valve cap.

Precautions necessary when sizing spheres:

  • Insure all air is evacuated from the sphere during filling and sizing.
  • Tighten all valve and valve caps firmly, but do not force threads.
  • If valve leakage occurs, replace entire sphere valve assembly if necessary.
  • Custom made to your exact requirements
  • 24 hour shipment
  • Precision laser cut from 1/4” Micarta (advise pipe size, schedule and percent oversize required)
