Update : well... my order of Frozenboost AN fittings and teflon braided hose came in . Nice looking AN fittings and teflon hose for the $$$ . well decided to put them thru the test . made up a few pieces with fittings and presurized them to 125psi (air) and drop them in water . well...they came thru with flying colors . nice AN fitting for the $$ IMO .
