Vented Cap Body Grease Fittings

Our standard body grease fitting features the Positive Flow Ball Support. This design directs the flow of the lubricant and/or sealant through the centre of the spring without passing through the spring coil, reducing the tendency to “pack-off.” The Positive Flow Ball Support is available in many other fitting styles.

Another feature of the standard body grease fitting is the heavy-duty radial rivet crimp. This special crimp provides the best “blow-out” protection of any available crimped style fitting. The radial rivet crimp process conforms to the latest revision of NACE.

The Free Flow fitting utilises a unique spring retainer that is threaded into the body of the fitting. This special retainer also acts as a ball support and spring guide, and its design allows for the Free Flow of lubricants and sealant around the spring, instead of through it.

• Only unrestricted flow path on the market-the straight-line passageway significantly reduces tendency to “pack-off.”
• 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.
• Meets latest revision of NACE-no cold working of materials.

Packing/Bonnet Injection Fittings

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.

• 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 conditions
• Meets latest revision of NACE-no cold working of materials.
