ERGAL DMR AIR-BRAKE piston head with DELRIN BEARING (TMTPDMR-E)

The front shape of the AIR-BRAKE piston head has been designed to effectively convoy the air inside the PAD of the cylinder head reducing to the lowest point the sound of the impact with the cylinder head. The DMR AIR-BRAKE piston head has the double O-RING of sealing/stabilization, to avoid contact with the cylinder interal surface. The total height of the TopMax piston head is standardized to the size of the other piston heads on the market. The ERGAL and DELRIN insert for fixing the piston head on the piston is slightly shorter than the standard market size, so you can use the TopMax piston head on any piston on the market.

The DMR AIR-BRAKE piston head is designed to have a narrow compression chamber to achieve a faster compression phase on the O-RING, a faster opening time and ensuring that the cylinder’s air volume is fully compressed almost instantly as soon as the O-RING overtakes the cylinder milling. We suggest to use the DMR AIR-BRAKE piston head to a maximum of 30bb/s R.O.Fs. configurations. The stress-tests on the DMR AIR-BRAKE piston head were performed with a more powerful springs than those required by italian law, so the product will guarantee reliability and performance even with more advanced configurations. For maximum performance, we recommend pairing the piston head with the TopMax piston and cylinder head.
