R417A Refrigerant Gauges

Am trying to source replacement refrigerant gauges with a R417A scale for a chiller that used to run on R22.

I have looked through Climate centre & kooltech product guides and searched the net but have found nothing as of yet.

Has anyone changed these in the past ?

Thanks,

SRW do a refco multi gas manifold with interchangable clip on scales, I think you can buy r417a scales for them. I don't think you can just buy the gauges, you have to get the whole manifold set first, the the additional clip on scale.
