I use this Harbor Freight sandblaster to blast with black grit/slag from Menards. I go about 100 psi and occassionally the hose will burst (and sand the floor or my legs). The manual says never go above 125 psi.

Any recommendations? I've got a new/stonger hose from Mcmaster-Carr but I can't get the clamps tight enough over the barbs to prevent leaking.
