Focus aircon compressor adapter
John Bonnett - 1/12/22 at 09:33 AM

I'm using a MK1 Focus aircon compressor and want to change it from solid pipes to AN threaded fittings for rubber lines. The same with the condensing radiator. I have been unable to locate a supplier of any adapters and wonder if anyone knows of a fabricator who would make up the adapters or indeed if there are any aftermarket options.

Thank you

John

Providing the link works, there are a few suppliers on ebay for the weld on fittings;

https://www.ebay.co.uk/sch/i.html?_from=R40&_nkw=an+fitting+weld+in&LH_PrefLoc=1&_sop=7

The only problem you may encounter is the original pipes are often vacuum brazed, and the zinc used for this tends to burn while you're welding the fittings, making things more difficult to weld.

I would also suggest that you use hoses only where a flexible section is required, the hose does allow gas to permeate slowly, the more solid pipe, the lower your self discharge will be on the system.
Type E hoses have the lowest permeation rates, approx 1/4 of the type C hoses, there are some that are lower again.

Also have a look here, there are quite a lot of adapters, hoses and fittings that are available for building the system up.

Hi Dave, thank you so much for taking the trouble to reply. I have already tried T7 who are very helpful but unfortunately they cannot help. The weld on fittings you have pointed out on Ebay might well be the way to go and I thank you for finding them for me. Thank you too for the useful information regarding the hoses.

Kind regards

John

I think the connector that fit that housing is an upset flange on an aluminium tube, and as stated the oems use as little flexible hose as possible due to gas permeation. Your options seem to be use a length of the original tube and weld an adaptor to it, tricky, or machine a stub end to match the pipe end form, and use the correct O rings for your gas and oil combination.

I'm hoping I've found the solution which as no surprise is available in the States. Those chaps really are spoiled for choice with all the goodies we can only dream about. I've been in touch and asked them to confirm dimensions but visually it looks promising.
