Need advice on FX hand pump lube

[slow_runner]

I had the same problem, could not find RENOLIT-RHF1 anywhere. The only thing that cropped up was this: evilbay.co.uk/itm/LQUID8R-FX-1-Synth-Grease-w-PTFE-Replaces-RENOLIT-RHF-Precharge-PCP-Airgun-Pumps/271115044952
Although I would think it would be OK to use the same silicone-based grease that Hill does.
Pse don't use 3-in-1 in these high pressure pumps, it could be very dangerous!

Thanks Angry and BB
I did come across that LIQUID8R, however nothing local, only from the USA for a few American dollars with a healthy freight rate.
It would appear that RHF1 is an industry classification for extreme pressure/temp range?
Will be making more enquiries on the dognbone today.
