Hydraulic hose end fittings are available in a variety of styles and materials. It is always important to follow the specifications for your tools and equipment when you select hydraulic hoses and crimp fittings. Using the wrong fitting can damage your equipment, reduce its efficiency, and fail under use. This is dangerous to workers and destructive to equipment.
Crimp fittings are manufactured for 1 and 2-wire hoses and 4-wire hoses. While it is often acceptable to use fittings designed for 4-wire on 1 or 2-wire hoses, it is not advisable to reverse that exchange. The fittings are designed to withstand certain pressure variations, and the incorrect fitting may fail under pressure, even if it has been crimped into place.
PTFE HOSE FITTINGS, T-SERIES
These are also crimped fittings that require pre-determined crimping pressure to insure proper function. This type of fitting is used with SAE PTFE hose.
THERMOPLASTIC FITTINGS, 3-SERIES
These also crimp fittings. They are used with nylon hydraulic hoses or thermoplastic hoses.
