The NS-Series, Hydraulic Nut Splitters are specially designed to suit standard ANSI B16.5 / BS1560 flanges. They contain a single-acting (spring return) or double-acting cylinder and interchangeable heads which provide maximum nut range flexibility. The tri-blade technology provides three cutting surfaces on a single blade while the grip tape and handle are included for more secure manoeuvrability. In additon, the splitters include an internal pressure relief valve for overload protection. A nickel-plated cylinder body for excellent corrosion protection and improved durability has been incorporated for harsh environments. The preset scale allows controlled blade extension, which avoids damage to bolt threads. A CR-400 coupler and dustcap are also included on all models.
