Brand new Viking Norseman double hose regulator #NOT9-A
Viking Regulator: A Vintage Diving Marvel
The Viking Regulator, produced between 1958 and 1963, became a key innovation in diving technology. Developed by Christensen Tool and Engineering Inc. in Connecticut, this double-hose regulator was noted for its unique “beer-can” shape and advanced pressure control, which relied on Schrader valves. Christensen’s team, led by Kaj Christensen and based on designs by engineer James P. Fay, aimed to make the Viking Regulator durable and efficient for mid-20th-century divers exploring underwater depths
Groundbreaking Design and Challenges
The Viking Regulator introduced several firsts, including a two-stage mechanism and the pioneering octopus feature, which allowed divers to share air. Initial tests by the Navy’s Experimental Diving Unit (NEDU) revealed some challenges, especially at greater depths where airflow could be limited by the Schrader valves. To address these issues, Fay collaborated with commercial diver George Swindell, refining the regulator’s design. Even with these adjustments, the Viking Regulator occasionally faced airflow restrictions in high-pressure environments, affecting its performance in demanding conditions
The Norseman Model for Navy Use
In 1962, Christensen developed a Norseman version tailored to U.S. Navy specifications, producing about 150 units. Each Norseman had an “N” prefix on its serial number, designating its military-grade status. This model differed from the Viking Regulator by excluding the Reserve and Flush lever but adding a respiratory resistance adjustment to meet Navy standards. The Norseman also used black hoses and added intake labels, which distinguished it for collectors today
Legacy and Collector Appeal
Today, the Viking Regulator is highly prized by vintage diving collectors. Its limited production and engineering innovations make it a treasured artifact, symbolizing an era of intense diving innovation. Owning a Viking Regulator offers enthusiasts a tangible connection to the history of underwater exploration and engineering advancements.
