Gates hydraulic hose crimper

Looks much the same as this one:-

A curious feature of Goindustry auctions, I've met it before, is that the final price was exactly the same as my maximum autobid, and was submitted *after* my autobid. I'm sure there's a rational explanation as to why bid wasn't the one which won, probably his autobid was higher than mine but???

explanation

Yes that one is (I think) a Gates MC1001 which does up to 1" bore. I actually got through to a helpful Gates chappy today who reckons mine is a Gates USA version. Apparently the two companies make similar but incompatible fittings and crimpers!! But he was a gloom and doom merchant wringing his hands and saying don't make up hoses as H&SE will chase up the bloke crimping the hoses in the event . . . . Probably right at a theoretical level. Another gem he dropped is that Gates have ceased making their longest running hose fitting range in favour of a new (and more expensive) range that is no longer compatible with the older crimpers. Personally I would have thought if you adjusted the old crimper to squash down to the recommended final diameter of the new fitting it would be crimped and the fitting wouldn't know (or care) which crimper squashed it there.

Haven't send one of those in years, Rather fitting particular that style of crimper. Can be a can of worms unless you're prepared to experiment. Tend to reduce inner tube diameter, particularly on smaller sizes. People soon learnt to have a relevant rod to insert in the being crimped fitting to check for diameter reduction. That worked on straight fittings, for swept bends and angled fitting required using the previous research. :-)

In the bigger sizes the crimper tended to behave itself as it was encountering a lot more resistance.

I may have some info later in the day if can persuade someone to go dig in a filing cabinet. However, owing to all the generic fittings about any setting chart tends to only a guide rather than a specific setting.

Tom, if you were able to dig that out it would be a great kindness. Good tip re a rod down the pipe, but it conjures up an image of all these pipe fittings blocked with stuck rods

Ahem, perhaps I should have wrote that in laundromatese? :-) One checks after one squeeze, perhaps?

I think these crimpers are designed to bottom out so as to establish the correct degree of crimping. The dies are intended only for the specific fittings recommended by the manufacturer. They are pretty fussy since a failed crimp in a system with high pressure hot oil can be very serious. They are most likely to blow off when you have the forklift up high with a heavy load!

Not that simple, Don because each set of dies has to deal with two different scenarios:- 1 and two wire hose, so settings do come into it. The problem normally lies in over-crimping rather than under-crimping.
