There are 3 common types of hydraulic hoses we see in basic hydraulics like tractors
R2, R16, R17
R2 is standard 2-wire braid hose. And in 1/4" it is rated ~5800psi and is 4" bend radius. (Meaning you can make an 8" loop or circle). This is the only type I have seen the reusable fittings sized for........and the hose is 0.590" outside diameter
R16 is also 2-wire braid and known as "half bend radius". For 1/4" it is rated for 5800psi also, and has a 2" bend radius. But the outside diameter is slightly smaller at 0.550" which is why they dont work for the field attachable fittings that basically thread onto the outside of the hose.
R17 is known as constant pressure hose. Both R2 and R16 have pressure ratings that get lower as hose size increases. R17 is a constant 3000psi rated hose through all sizes. It is a one wire braid on 1/2" and smaller hoses and jumps to 2 wire on 5/8" hose and larger. It is also half bend radius like the R16. For a 1/4" hose (rated at 3000psi obviously) it has an outside diameter of 0.500". So again, wont work with the field attachable fittings.
If you want the most flexible hose....sadly you have to use crimp fittings for the specific hose.
I like R16 or everything I use because its much higher working pressures in the smaller hoses that our small tractors normally use in combination with its flexibility make it better than R2
