The BOSS BLACK range of AG Cylinders are 100% pressure tested and designed with Dual Ported UN-O-ring threads. This innovation provides 2 ports at the rod end and 2 ports at the rear clevis end of the cylinder to suit a wider variety of applications.
ALL BOSS BLACK cylinder piston rods are hard chrome plated, the barrel is CDSM honed and the rod gland is manufactured from ASTM A536 ductile iron. This tough and versatile range is shipped with port sealing plugs, and in plastic bags, to prevent dirt ingress during transportation and storage.
