The valve design includes significant improvements not found in similar versions from other manufacturers. The Norell High Pressure Valve requires no special tools or tubing preparation procedures prior to use. Secure, leak-free connections to standard 1/8" O.D. laboratory instrumentation pressure tubing need only be made finger-tight, unlike competitor's versions that often leak at this connection point even after tightening with a wrench.
We supply the necessary components of the compression tube fitting (consisting of a compression nut, ferrule and gripper) with the High Pressure assembly, whereas other manufacturers do not. The special compression fittings do not permanently attach to the pressure line. This permits removal and reuse in other locations or connection to different gas supplies without installing dedicated metallic double ferrule fittings at each point of use. We also include a short length of 1/8' O.D. Type 316 stainless steel tube to provide versatility when making pressure connections.
