Brass series with tie rods
The hydraulic cylinders of the brass series with tie rods are designed to work at very high pressures. The brass material is also appealing aesthetically considering that these cylinders are usually used in the yachting sector, but also others. The cylinder tube is made of brass, a material which has higher resistance to pressure than aluminium. The piston rod is made of stainless steel, chromed and rectified; the chromium plating in a protected environment guaranties a high quality plating, and an excellent protection against the marine corrosion, combined with a very smooth surface guaranties a long endurance of the seals. The chromium helps to eliminate at least 30% of the friction caused by the use of seals and its hardness protects the piston rod from accidental scratches which could damage the seals. The support is made of bronze. All MARSILI cylinders are certified CE and are approved by the most important international classification societies.
