typical dime store products. They will work, but the leaky hose, failed/failing ram seals, pull ram that crapped out after one use; were part of the bargain on My HF ten ton unit..
I have a similar 4 ton unit. That one has one smaller broken attachment and a leaky hose.
It would be nice if the hose couplers had the same thread on both units, but they don't.
By the time I upgrade both units with hoses and couplers from a more respected manufacturer, I may be better off simply buying a complete higher quality unit .
