Re: Is it possible to fix this a,c pipe

Yes, £800 (approximately $1,000 USD) is expensive. But your pictured lines with the chewed-up Springlock connection have twists and turns, and an apparent crimp besides, making a fix unlikely. You'll be better off having the shop handle it from start to finish. They will install new lines and whatev...

Re: C2 Corvette parts search

I didn't realize at first that your '66 Corvette has an STV, similar to the one I had years ago on a new '62 Impala/283/Powerglide with factory A/C. The STV was hidden under the right-front fender in the engine bay and operated manually via a cable controlled by a horizontal slider on the lower-cent...

Re: C2 Corvette parts search

Are you going to keep it R-12, or do you intend to convert it to R-134a? if the latter, you'll need to re-calibrate your original POA (STV) valve to the "newer" refrigerant. If your original POA valve is intact and rebuildable, why replace it? Several professional rebuilders with an Intern...

Re: Newbie, installing "custom" system

The ATCO fittings at 7.95 mm OD seem about right. The ones that measure as small as 7.6 mm appear to be out of spec to me.

Re: Newbie, installing "custom" system

No chance of any sub-standard, out-of-spec fittings to which Tim alluded earlier? Not trying to give you a hard time, just attempting to get to the bottom of this. To review: For a standard 5/16" (7.9375 mm) ID barrier hose, the fittings should measure—according to my Mitutoyo digital caliper—3...

Re: Newbie, installing "custom" system

I don't remember anymore whether you made mention earlier in this very long thread, but I believe you can go with either a 5/16" ID (7.9375 mm) reduced barrier or standard barrier hose, each of which, IIRC, takes industry-standard 3/8" (9.525 mm) fittings. The only measurable difference be...

Good deal. If anyone can help with that, Tim can.

Re: 1969 Cadillac Sedan DeVille

Some additional comments about R-1234yf... Last summer, I purchased a new Toyota 4Runner Limited that has the above mentioned refrigerant, my first personally owned vehicle that didn't have either R-12 or R-134a. The best it would cool for me on a hot summer day here in the humid South (~90°F) was i...

Re: Newbie, installing "custom" system

I would worry because it might not seal tightly enough after crimping, which you wouldn't notice until after the system is assembled and charged.

Re: Newbie, installing "custom" system

The soft copper washers probably would help to ensure a leak-free seal, as would the Nylog Blue. I've never used the copper washers, though.
