Wellhead Grease Fittings, Packing / Bonnet Injection Series

Brand: Parker PGI
Parker PGI’s Packing / Bonnet Injection Wellhead Grease Fittings come in two designs.

These Wellhead Grease Fittings are a Free Flow or a floating ball - tapered cavity design and a floating ball - tapered cavity design that is available in NPT or UNC threads.

The Free Flow design of the Body Grease Fitting has been incorporated into our Packing Injection Fittings.

Compared to standard floating ball designs, the Free Flow's specially designed spring retainer allows even the heaviest of lubricants and/or sealant to flow freely through the Packing Injection Fitting.
Features
  • Service up to 10,000 PSI
  • Positive back seating is provided without relying on the presence of back pressure
  • Guaranteed against "Blow Out" when used within design limitations of the fitting. Excellent in extreme cold environments
  • Increased flow rates due to the unrestricted flow path
  • 316 SS or 4140 body materials meet latest revision of NACE - no cold working of materials
  • Offered in NPT threads only
