The ERMAL 7075 cylinder line of TopMax Elaborazioni is entirely made of CNC machined solid bars, and this allows you to better manage the expansion / shrinkage phases (due to overheating by rubbing the O-RING on the walls of the cylinder itself) of the finished product when working in contact with the O-RING during the firing cycles. The ERGAL expansion / shrinkage memory effect allows the O-RING of the piston head to work tightly without unnecessary efforts even for R.O.F. high, giving greater reliability and consistency even in shooting

Technical Specifications of the C-31.00mm 2-hole cylinder:

Cylinder length - 72.20mm,

External cylinder diameter - 25.50mm,

Internal cylinder diameter - 23.85mm.

Internal finish of ANODIZING and POLISHING, to ensure the reduction of friction between the contact surfaces, greater smoothness and resistance to rubbing of the O-RING during use.

The cylinders of TopMax Elaborazioni are compatible with the majority of the GearBoxes on the market. TopMax Elaborazioni recommends the use of the BLUE C-31.00mm cylinder in combination with barrels between 100.00mm and 150.00mm in length.
