Eaton Aeroquip AE313 hose assemblies use two piece fittngs instead of the three-piece fittings used on previous PTFE 4-spiral wire hose assemblies. The flared and flareless fittings in straight, 45º and 90º elbow configurations (in the 1-inch size) of Aeroquip brand AE313 hose are smaller in O.D./length ranging from 20% to 65% compared to previous fittings.The overall weight of the AE313 hose assemblies is substantially reduced due to the simplified construction of the fittings.
