Is your compressor taking longer and longer to fill, or no longer reaching cut-out pressure? With use, the piston ring wears and the pump loses compression. This piston ring and seal kit restores the pump's tightness and your compressor's original air flow.
It is the spare for the AP1500 oil-free silent pump fitted to PRO104 and PRO204 compressors. It includes the piston ring and seals, everything needed for a complete, leak-free repair.
It is one of the most cost-effective repairs on an oil-free compressor: small, inexpensive parts that restore the lost performance to the unit.
✅ Key benefits

Complete kit: piston ring and seals.
Specific to AP1500: for PRO104 and PRO204.
Leak-free after repair: new seals every time the pump is opened.
Inexpensive repair: avoids replacing the whole pump.
🏗️ What it's for

📋 Technical specifications
Pump: AP1500 silent, oil-free

💡 Vetonek tip: fit the new ring carefully so as not to score the cylinder and always replace the seals when opening the pump; reusing an old seal is the most common cause of leaks after a repair.
