View Full Version : Metric adapter for MR2

03-04-2009, 04:31 PM
I've searched the forum, but some similiar questions are either not answered or not too clear to me.

It looks to me that what is advertised as "spyder metric adapter" will not fit MR2. Thread sizes on both ends of that adapter look similiar. When comparing to MR1 (10mm), on MR2 it is bigger (12mm).

Is there any short and straight or 90 adapter for 12mm (male) to 1/8 NPT (female) to buy in USA? I do not know how to search for it on google - to many hits. Or any 12mm elbow, into which I could try to fit some straight 1/8 NPT adapter?

I could try to plug the hole with a plain screw, but if I drill through the side, I will again need some adapter as I cannot get imperial (US) threaders in my country :(

To left is CP from MR2 (also serves as ASA adapter), and to the right is hose from MR1, both of which screw directly into body.

You can use a CA to 1/8"NPT adapter and screw the line directly into that. You'll have to leave that small ASA on though. You'll find the adapter I'm speaking of on the ends of remote lines. I've seen them for sale by themselves at some online stores. They have a standard male ASA thread on one end and female 1/8"NPT threads on the other. I doubt you're going to find anything so you can screw the line directly into the body -

Yep, I was thinking about that as my last option. I'll go check local stores, but I'm doubtfull. Not that I do not think that such adapter exists, but those blue collar sellers always react "Whadaya need it?", and in case I mention it is high pressure they turn all scientific :P

Didn't think of this initially but, you might look for a reducer in the right threads. I doubt you'd find one at like Home depot, ect but more at like an auto supply store, Firestone, transmission place, welding supplies, place that sells fasteners(screws, bolts, nuts) only and like that. Not sure about the ones in the body but the others are 1/8"NPT of course -

No go in local shops or workshops so far.
Metric thread on MR2 is definitely M12. I was able to find a hose that fits, but its for concrete mixer and is up to 10 bar (150 PSI), which I think is not enough for MR2. Also, they have them only with straight fittings.
No local workshop has the tools, will or understanding. I'll try to visit few more, but I'm kinda loosing my nerve with sellers. After 10 minutes of explaining and drawing graphs, I have to yell at them as they try to screw almost anything into hole on MR2. Pretty lame adventure, as I realized that 1/8 is very popular for air, water and hydraulics fittings here. Actually, I have them on my airbrush compressor. However, depending on the order I ask (air, water or hydraulics), you can actually hear loud CLANG from sellers head as he switches tracks form air to water fittings and disengages imagination.
I've sent mails to several shops in US, still waiting for their reply.

I'm considering drilling a new hole on the side of body that will have 1/8, and I'll fit macroline adapter directly. I hope I'll be able to find metric plugs more easily.
But, I cannot find threading tools. Can someone point me to the right tool (name and pic) so I could start nagging in WTB forum? Thanks!
