Brief description:
1.Piston styled to spring, two-point (Nylon) valve guide design, piston action offers fine qualities such as balance and smooth movement.
2.Piston is made from nickel-plated nickel silver which offers good protection against corrosion/ oxidation.
3.Through extra honing, the valve cast inner walls have excellent degree of surface roughness and have the “#” Shaped etching refueled for lubrication. This quality reduces frictional damage, lowers noise due to movement and helps the piston recovery action to be smoother.
