So, let’s start!

Why Your Air Compressor Leaking From the Bottom! [Fixed]

1. Worn or Damaged O-Ring

The O-ring is a small, circular ring that helps to create a seal between two surfaces. If this O-ring is damaged, it can cause your air compressor to leak oil from the bottom. You can replace a damaged O-ring by purchasing a new one from your local hardware store.

2. Damaged Piston Ring

The piston ring is a small, metal ring that helps to seal the gap between the piston and cylinder wall in your air compressor. If this piston ring is damaged, it can cause oil to leak from the bottom of your air compressor. You can replace a damaged piston ring by purchasing a new one from your local hardware store.

3. Worn or Damaged Valve Seal

The valve seal is a small, rubber seal that helps to create a seal between the valve and the cylinder head in your air compressor. If this valve seal is damaged, it can cause oil to leak from the bottom of your air compressor. You can replace a worn or damaged valve seal by purchasing a new one from your local hardware store.

4. Loose Drain Plug

The drain plug is located at the bottom of your air compressor and is used to drain any condensation that has accumulated in the unit. If this drain plug is loose, it can cause oil to leak from the bottom of your air compressor. You can tighten a loose drain plug by using a wrench or socket set.

5. Cracked Cylinder Head

The cylinder head is located at the top of your air compressor and houses the valves that control the flow of air into and out of the unit. If this cylinder head becomes cracked, it can cause oil to leak from the bottom of your air compressor. You can replace a cracked cylinder head by purchasing a new one from your local hardware store.

6. Failed Pressure Relief Valve

The pressure relief valve is located at the top of your air compressor and is used to release any excess pressure that builds up inside the unit. If this pressure relief valve fails, it can cause oil to leak from the bottom of your air compressor. You can replace a failed pressure relief valve by purchasing a new one from your local hardware store.

7. Worn or Damaged Gasket

The gasket is located between the cylinder head and pump body in your air compressor and helps to create a seal between these two components. If this gasket becomes worn or damaged, it can cause oil to leak from the bottom of your air compressor. You can replace a worn or damaged gasket by purchasing a new one from your local hardware store.”
