These fittings are the only ones rated to 900 psi, and the hose to 1500 psi. This is the working pressure, not the burst pressure which is 3 times higher.
These fittings and hose are the answer to all the blown hoses of the past.
They are push fits just like the ones you already have, but much stronger.
Check out my thread "blown hose or fittings, LOOK HERE !!".
