As an alternative...would a 45* double flare work?

Year: 71
Make: hevy
Model: Blazer
Engine Size: 350
Refrigerant Type: 134
Country of Origin: Canada

Just wondering about alternative connection types.
I know GM used the O-rings, Ford + Chrysler use spring locks etc.

As far as fabing up your own lines on a totally custom install...would a 45* double flare or even a 37*single flare connection leak?

I mean as far as pressure's go those type of connection see 3000PSI and are designed for automotive use.

Would Nylog help seal them up.

Just a question.
Please educate me.

Thanks in advance.

Flare fittings and SwageLoks are designed to seal without lubricant or seal.

Metal on metal seal can be fully airtight, works fine for refrigerant stuff. Not used much on production cars because the fittings are more expensive and also require more skill in assembly. Proper torque is essential to get a good seal, but over-tightening will bend something and cause leaks.
