Thanks, Bill for getting me off my duff to say a few words re rubber hose
for LN2 transfer. DON'T. I know one person who eventually lost an eye
when a rubber hose fractured. I have been using thick rubber vacuum hose
thinking it must be safe. I was wrong. After about a year of use the hose
split and a piece flew off about 2" long. This could have injured an eye
easily. I have a quote for a 6' stainless flex hose for about $230 from
airproducts. I think MVE is the manufacturer. Also Southland Cryo. sells
them 800-usa-cryo. Be Safe, Lew
