1970's Imperial microbore....

[thereisawizza]

Hi all, had a 'mare the other night, "just cutting off" 2 x f&r's to an old towel rail, couldn't get an 8mm fitting onto the pipe and a 10mm flapped around like a clowns hat! Managed to unsolder some scrap adaptors from the pipework (which unfortunately had no maker marks on them) and re-use as a temp fix. Rung Yorkshire, no imperial microbore fittings available anymore?!?!

Any of the "mature" peeps on here know what this may be? Did microbore used to be 1/8" before metricicityness

Cheers, in advance, Rich.

Somebody had been using 1/4 or 3/8 soft copper.
It's amazingly still used on caravans and motor homes. Was used on oil likes too for flared fittings.

old pipe was nominal bore also 5/16 but was and is almost the same (within 1 thou) of 8mm. maybe the pipe was not round

I would have thought 1970s pipes would be metric, - unless very early 1970s.
About 1973 was the last of imperial.
As above, ^ pipes could be a bit 'flat' were you cut them and even a brass compression fitting tapped onto to them will make them more round.

Thanks for your confidence in my pipe cutting guys Can't find my micrometer at the mo but on a steel rule is just under 9mm. The whole house is done it in, has adaptors to 10mm in all rad valves, elbows and tees; their appears to be no fittings in this size anywhere? That would be too easy as they may have something stamped on the side of them....

3/8 compression then

A DIY job done by a good old fashioned engineer with pipe and fittings he got from work no doubt, not too bad either, it's lasted 40 yrs
I wonder how many of todays install will last that long

Can any please tell me where I can buy a replacement late 1960's - early 1970's 8 valve Manifold, for use with 8mm Microbore pipes please?
