Tube & Fitting Assemblies permit safe, reliable and convenient operation of miniature Joule-Thomson Cryostats. The standard 0.040 inch (1.0 mm) diameter x 0.005 inch (0.1 mm) wall copper-nickel tubing has been found to be a convenient means for plumbing high pressure gas lines. The flexibility of the small-diameter tubing is essential in reducing the stress imposed on glass Dewars by high pressure plumbing. Tubing and fittings are rated for 7,500 psi service; burst pressures are in excess of 20,000 psi.

R. G. Hansen and Associates' miniature pressure fittings are designed for compatibility with all RGH miniature cryostats and with 0.040 inch (1.0 mm) flared tubing. Adapters are available to fit military and commercial hydraulic components.
