FAQs

What does '5/16 UNF' mean?

5/16 UNF refers to the thread size. '5/16' is the nominal diameter in inches, and 'UNF' stands for Unified National Fine, indicating a specific thread pitch (number of threads per inch) common in imperial systems.

Can I use these with any grease gun?

You can use these with any grease gun that has a coupler specifically designed for a 5/16 UNF threaded grease nipple. Not all grease guns have interchangeable couplers, so check your equipment.

What is the purpose of the 45° angle?

The 45° angle is designed to provide better access to lubrication points that are located in tight or awkward spaces, making it easier to connect a grease gun.

How many grease nipples are in a pack?

Each pack contains 50 Connect Grease Nipples.

Are these nipples suitable for high-pressure applications?

These nipples are designed for standard greasing applications. While durable, extremely high-pressure industrial systems might require specialized fittings. Always refer to the machinery's manual for specific lubrication requirements.

How do I clean a grease nipple before installation?

Wipe the nipple and its threads with a clean, dry cloth. If there is stubborn grease or dirt, a mild solvent can be used, ensuring it is completely dry before installation.

Troubleshooting

Grease not entering the fitting

Check if the grease gun coupler is fully engaged with the nipple. Ensure the nipple is screwed in correctly and not cross-threaded. Verify the thread pitch matches your grease gun coupler.

Nipple is difficult to screw in

Confirm that the thread size (5/16 UNF) is correct for the port. Clean both the nipple threads and the port threads before attempting to screw it in again. Avoid forcing it if resistance is significant.

Grease leaking around the nipple base

Ensure the nipple is tightened appropriately. If the leak persists, the mating surface or the port may be damaged, requiring inspection or repair.

Pros and Cons

Pros

  • Enhanced accessibility due to the 45° angle.
  • Broad compatibility with standard 5/16 UNF equipment.
  • Durable build for long service life.
  • Cost-effective bulk packaging.

Cons

  • Specific thread size (5/16 UNF) may not fit all equipment.
  • Requires a compatible grease gun with the correct coupler.
  • Angle might still be challenging in extremely tight spaces.

Setup, Compatibility & Care

Setup:

  1. Ensure the grease nipple thread is clean and free from debris.
  2. Screw the grease nipple into the designated port on the machinery by hand until snug.
  3. Use a wrench to tighten gently; do not overtighten, as this can damage the threads or the fitting.
  4. Attach a compatible grease gun coupler to the nipple.

Compatibility:

  • Thread: This nipple features a 5/16 UNF (Unified National Fine) thread. It is compatible with grease guns and fittings designed for this specific thread size.
  • Grease Guns: Use with standard manual or pneumatic grease guns equipped with a suitable coupler for 5/16 UNF nipples.

Care:

  • Keep nipples clean and protected from dirt and moisture when not in use.
  • Replace any nipples that show signs of damage, corrosion, or wear.
