Cylinder Head Repair Kit
This kit contains the head valve O-rings and gaskets which form the primary seal for the main cylinder. A leak from the top of the tool or the exhaust port during the reset cycle indicates that these seals have flattened or hardened, preventing the head valve from seating correctly under pneumatic pressure. Replacing the head-side seals restores the pressure differential required for the tool to cycle without losing air.

Trigger Valve Assembly
If the leak is heard coming from the trigger area, the internal O-rings of the trigger valve have failed. These small seals are subject to high cycle counts and are often the first to fail if the tool is not lubricated daily. The assembly replacement is the standard service procedure as individual O-rings within the plunger are difficult to seat without specialized tools.

O-Ring (A) Piston Driver
The piston O-ring maintains the seal between the driver blade assembly and the cylinder wall. A failure here results in air 'bypassing' the piston, often manifesting as a leak through the nose of the tool or a significant loss in driving power. This component is a high-wear item that requires periodic replacement to maintain the tool's kinetic energy output.
