Parker's (improved) 472LT and 792LT low temp hoses should be used instead. They provide the same low temperature rating for your extreme applications as well as a higher pressure rating in most sizes. 301LT hose is rated to 2,000 PSI in 1” size to 5,000 PSI in 1/4” size; 722 is rated from 2,500 PSI in 1-1/2” through 4,000 PSI in 3/8” size. By comparison, 472LT ranges from 2,500 PSI in 1” ID to 5,800 PSI in 1/4” ID size and 792LT hose features constant pressure rating of 6,000 PSI in all sizes (1” ID through 1-1/2” ID).

Be aware that 472LT hose has a lower working pressure rating than 722LT hose in sizes 5/8” through 1”.

Use of Parker 792LT in place of 722LT hose will also simplify hose fitting selection during hose fabrication. The 797LT uses 79-Series fittings in all sizes, where 722LT uses a combination of 43-Series and 71-Series fittings, depending on size. This simplification reduces the possibility of crimping the wrong series fitting onto hose.
