standerd fittings used in hydrolic systems

Big Will

I have a job coming up next week. We need to move a large boiler away from the wall. I bought two hydraulic rams and a pump to push it with. cheap and easy right? I needed 1/4 X3/8 inch bushings to assemble the hoses. while tightening the fitting it exploded. I had filled the hose with fluid before assembly to reduce the amount of air I would need to purge. When I tightened the fitting the pressure must have become very high because the bushing just exploded and shot across the shop. After changing my shorts I got to thinking. Was that just a bad fitting or are regular pipe fitting to week to cary hydraulic pressure?

explosive pressure

i think the pressure of hydraulic systems can be be much higher than the 150 psi most plumbing fittings are rated for--such as 1000 psi.
your experience is similar to those of people changing their steam systems to hot water--nbc
