I recently had a discussion with my General Manager. Actually it was a one way discussion, since he is the boss. At my plant we use hydraulic crimp fittings with o-ring face seals, and our equipment uses accumulators with a pre-charge of 900psi. In a fire situation, this could prove disasterous,as the o-rings would melt,and atomised oil will become airborne, but he is convinced that h46 is fire resistant.I need literature to justify claims either for, or against this question, can you help?

Get a data sheet and look at it Nuto is/was a mineral oil based hydro oil. as such is NOT fire resistant will not be aproved by your insurance company for use in areas of open flame or sources of combustion.

For that you need a high water based fluid or a gylcol fluid.

Hi Bruce, many thanks for your input. I will follow up.

This will get you to Nuto H.
