The Nor coupling originated in Norway and was used for many years in shipbuilding. Nor couplings are available in 1”, 2” and 3” (Nor Las1, Las2 and Las3) and are used for delivery purposes only. For suction operations, Norway uses the well-tried Storz coupling. The Nor coupling is also symmetrical, but what differentiates it from Storz and Gost couplings, are the locking rings. For safety reasons, we offer the Nor couplings only as pressure forgings in aluminum and brass. In addition, the Nor Las1 is available in stainless steel.
