Thanks to all who gave their 10c worth (or other currency) to raise the safety
awareness of rubber LN2 tranfer hoses.
We found a real inexpensive solution to the problem. We purchased a 10 Ft
(3.05m) stainless steel standard gauge metal hose with a 1" (25.4mm) ID and
1-1/8" OD, with a 6.5" minimum inside bend diameter. We placed a rubber hose of
7/8" OD, 5/8" ID inside the metal hose over the entire length. The home made
assembly is very flexible, easy to use and in our perception very safe. The
metal and rubber hoses could be joined together at the ends via adhesive tape.
We would appreciate any comments or questions.
The 10Ft hose was purchased for about $25 from McMaster-Carr Supply Company,
600 County Line Rd., Elmhurst, Illinois 60126-2081. Phone (708)833-0300. They
sell it in any desired length.
