Hd.Valve Piston

Fix Number FIX10246998

Manufacturer Part Number 180450-S

This is a manufacturer-approved replacement head valve and is sold independently. It controls the amount of air that enters the cylinder when the trigger is initiated. This action creates an imbalance in pressure between the cylinder and the air reservoir, allowing the head valve to open, firing the piston. The head valve can harden and crack and the valve body itself can break too. This will usually become obvious because air will leak from the gun exhaust. To access this part for the repair, you will need to remove the top cap from the nail gun.

O-Ring

Fix Number FIX10246996

Manufacturer Part Number 180448

This is an OEM replacement O-ring for a nailer, sold individually. This O-ring is what seals the cylinder to the housing of the gun and creates separation between the upper and lower air chambers. Due to its rubber material, over time, it can wear. For this repair you will need to remove the cap, disassemble the head valve, remove the spring, and remove the old O-ring. Apply some lubrication to the new O-ring and place it on the valve.

Piston Ring

Fix Number FIX17016268

Manufacturer Part Number N905972

This is an OEM piston ring and is sold individually. The seal allows pressure in the cylinder when the gun is engaged. The pressure pushes the piston down into the cylinder. This piston ring will deteriorate with time and this seal will loosen. When the piston ring is not sealing as it should, the driver can lose power and not work at all. This is a very simple repair and starts by removing the top cap from the tool. Next, remove the piston and ring. The new piston can now be installed in its place. The new piston ring fits over the top of the piston, just be careful not to damage it.
