Lubrication Fitting And Why It Is Essential To Equipment Longevity

Lubrication fitting is a vital element in any machinery or equipment that has moving parts. A grease nipple is a fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun. Grease nipples are available in different threads angles, materials and finishes. In the United States, “grease nipples” are generally known as “grease fittings”.

Before lubrication fittings or a grease system existed, bearings were lubricated in various other ways that tended to be more maintenance intensive and often provided less effective lubrication. For example, a machinery bearing in the 19th and early 20th centuries was a plain bearing with a cross drilled hole to receive oil or grease, with no fitting at its mouth, or at best a cap or a cup. Lubricants were delivered under no pressure other than gravity. For example, oil was gravity fed into the hole, or grease was then pushed in. Grease guns were used to feed the grease with higher pressure, but the lubrication fittings were not as good for making a clean, sealed contact, and they were less widely used than today.

Understanding Lubrication System Functions

Function Of A Grease Nipple Work

Lubrication fittings are used to lubricate mechanical parts which require grease. A spring loaded ball inside the lubrication fitting compresses when pressure is applied with a grease gun, which then allows the grease to flow through the fitting into the application. After pressure is released from the grease gun, the spring-loaded ball check returns to the head of the fitting and stops dirt and other contaminants from entering the oil lubrication fittings as well as preventing grease from escaping through the head of the fitting.

Lubrication Fittings Accessories And Component Parts

High Pressure Lubrication Hose and Fittings for Central Lubrication

The high pressure hose and fittings are suitable for grease lubrication and central lubrication systems of all conventional lubrication system manufacturers.

High pressure hoses are used in lubrication systems to connect the progressive distribution unit with the lubrication point or the relubrication distributor to the lubrication point. The materials have excellent resistance properties and are insensitive to oil, grease and lubricants. They are suitable for application in central lubrication systems.

Our range of high pressure fittings and hoses:

  • Type LL Lubrication Compression Fittings
  • Push-in Lubrication Fittings
  • Straight Extensions
  • Lubrication Adaptors
  • Banjo Fittings
  • High Pressure Reinforced Hose
  • Ferrules for 8.75mm OD Hose
  • Ferrules for 11.3mm OD Hose
  • Inserts for 8.75mm OD Hose
  • Inserts for 11.3mm OD Hose
  • Tube & Hose Protection

How To Eliminate Hidden And Hard To Reach Fittings

Hard to reach lubrication fittings can cause maintenance problems for all types of machinery. Hidden or guarded lubrication fittings can lead to production downtime, higher operating and maintenance costs, and the risk of personal injury. All lead to poor lubrication fitting access. How do you eliminate these problems? By using Remote Lube Fitting Systems.

The benefits of such lubrication fittings accessories are:

  • Easy access to lubrication fittings
  • Easier, quicker and safer lubrication
  • Assures that all bearings are lubricated
  • Bearings can be safely lubricated while machine is operating
  • Reaches hidden, inaccessible or hazardous bearings
