Features and Benefits
The GRASSO Piston Rings provide an excellent seal between the piston and the cylinder, ensuring complete compression of the refrigerant without pressure loss.
They also regulate the flow of lubricating oil, preventing excess oil from entering the compression chamber — reducing contamination and enhancing overall cooling efficiency.
Designed specifically for RC12, RC612, and RC912 compressor models, these piston rings fit perfectly without modification, reducing maintenance time and improving operational safety.
They also help protect key components such as pistons, cylinders, and connecting rods, extending the compressor’s service life.
In addition, GRASSO piston rings contribute to maintaining internal system balance, enabling smooth, continuous operation with less noise and vibration — ensuring stable and efficient compressor performance over time.
