Grease guns and fittings

SOLANO GREASE GUNS AND FITTINGS
To effectively use a grease gun or press, you need compatible grease fittings (also known as Zerk fittings or grease nipples) that allow grease to flow directly into lubrication points without leakage. The right fittings ensure a secure connection and efficient grease delivery.

Types of Grease Fittings

Standard (Straight) Grease Fittings

• Description: The most common type, with a straight shape.
• Use: General-purpose lubrication points on machinery, vehicles, and equipment.

Angled Grease Fittings

• 90-Degree Fittings: Suitable for tight spaces where access is limited.
• 45-Degree Fittings: Provide better access in moderately tight spaces.
• Use: Ideal for areas where straight fittings are inaccessible.

Flush Grease Fittings

• Description: Installed flush with the surface of the equipment.
• Use: Suitable for applications where protruding fittings might be damaged or obstruct operation (e.g., in moving parts).

Button Head Grease Fittings

• Description: Larger head size and designed for high-volume grease delivery.
• Use: Heavy-duty applications such as construction equipment, mining machinery, and industrial presses.

Pin-Type Grease Fittings

• Description: Have a small pin-like shape instead of a ball check valve.
• Use: Common in older machinery and some specialized industrial equipment.

Drive-Type Grease Fittings

• Description: Driven into a hole instead of being threaded.
• Use: When threaded fittings aren't an option or for quick installations.

Metric or Imperial Grease Fittings

• Description: Differ in thread size and pitch, based on regional standards.
• Use: Ensure compatibility with equipment specifications (e.g., metric fittings for European machines).

Pressure-Relief Fittings

• Description: Have a valve that releases grease if excessive pressure builds up.
• Use: Prevent over-greasing or damage to components.

Choosing the Right Grease Fitting

Thread Type and Size

• Ensure the grease fitting threads match the equipment. Common thread types include:
  • SAE Standard (e.g., 1/8" NPT).
  • Metric Threads (e.g., M6, M8).

Operating Pressure

• Heavy machinery might require high-pressure fittings like button-head types.

Accessibility

• Use angled or flush fittings for hard-to-reach or confined spaces.

Material and Durability

• Opt for stainless steel or zinc-plated fittings in harsh environments to resist corrosion.

Grease Gun Couplers

To connect the grease gun to the fittings, you need the appropriate grease gun coupler. Here are some types:

Standard Couplers

• Compatible with most grease fittings.

Locking Couplers

• Lock onto fittings to prevent accidental disconnection and minimize grease leakage.

Needle Couplers

• Designed for flush or pin-type fittings.

Angle Couplers

• Allow access to fittings in tight or angled spaces.
