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)
