SOLANO Recommendations for Grease Fittings and Tips for Their Installation and Maintenance

Recommendations for Specific Grease Fittings

Standard Applications (General Machinery & Vehicles)

• Type: Straight or angled grease fittings.
• Material: Zinc-plated steel or stainless steel (for corrosion resistance).
• Example:
  • SAE Standard: 1/4"-28 UNF thread straight grease fittings.
  • Metric Standard: M6 x 1.0 straight grease fittings.

Tight Spaces or Obstructed Areas

• Type: 90-degree or 45-degree grease fittings.
• Material: Stainless steel for durability.
• Example: M8 x 1.0 90-degree grease fittings for confined lubrication points.

Heavy-Duty Applications (Construction & Industrial Machinery)

• Type: Button-head grease fittings.
• Material: Case-hardened steel for high-pressure tolerance.
• Example: 5/8"-18 UNF button-head fittings for mining or construction equipment.

High-Temperature or Harsh Environments

• Type: Stainless steel grease fittings or pressure-relief fittings.
• Material: Stainless steel or brass for resistance to heat and corrosion.
• Example: M10 x 1.0 pressure-relief fittings.

Older or Specialized Equipment

• Type: Flush or pin-type fittings.
• Example: 1/8" NPT flush grease fittings for older industrial tools.

Installation Guidelines

Prepare the Installation Area

• Clean the hole or port where the grease fitting will be installed to remove dirt, grease, or debris.
• Check for thread compatibility (SAE, metric, or pipe threads) to ensure a proper fit.

Apply Thread Sealant (Optional)

• For threaded fittings, use a thread sealant or tape for a leak-proof connection.

Install the Fitting

• For threaded fittings: Screw them in using a wrench or socket until snug. Avoid overtightening to prevent damage.
• For drive-type fittings: Use a mallet or hammer to gently tap them into the hole.

Test the Connection

• Attach the grease gun coupler and apply grease to verify that it flows smoothly into the lubrication point.
• Check for leaks or grease ejection from unintended areas.

Maintenance Tips

Regular Inspection

• Periodically check fittings for clogs, damage, or corrosion.
• Replace damaged or corroded fittings immediately to maintain lubrication effectiveness.

Unclogging Fittings

• Use a fitting unblocker tool to clear clogs caused by dried grease or debris.
• Soak stubbornly clogged fittings in a solvent like kerosene before cleaning.

Grease Compatibility

• Ensure that the grease used is compatible with the fitting and the equipment's specifications (e.g., NLGI grade and type).

Protect Fittings

• Install caps or covers on grease fittings to prevent dirt and contaminants from entering.

Avoid Over-Greasing

• Apply grease gradually and stop once resistance is felt to prevent over-pressurizing seals or bearings.

Recommended Tools and Accessories

• Grease Gun Couplers: Lock-on grease couplers for secure attachment.
• Grease Fitting Assortment Kit: Includes various types and sizes of grease fittings for multiple applications.
• Grease Fitting Installation Tool: For inserting or removing fittings easily.
• Grease Fitting Caps: Prevent contamination when fittings are not in use.
• Unblocker Tool: Clears clogged grease fittings quickly.
