Is it possiable to remove the hose off of these type of fittings? Please see attached pictures. This is my A/C system on my 1969 GTO.

Looks like an aftermarket repair or an add on a/c unit. Factory stuff is crimped. A/c hose is tuff. It has to handle a lot of pressure and heat.
Those clamps are a step above your average hose clamp.

Yes, you can take it apart. Remove freon from system. Take a small screw driver or hose pic, Us a a drop of a/c oil or atf on the tip of the tool. Work the tool patiently between pipe and hose until it brakes loose with twisting effort.

That is factory and No sense to try and save the house of that age and condition, just slice the end hose and gently peel off.
The end of those fitting are barbed and will damage the inner portion of the hose as you attempt to twist it off likely effecting sealing upon re-use.
HD PSI / AC hose is avail;

I bought new hoses already made up from Classic Auto Air that use the same clamps as the ones you pictured.

Thanks Gents, glad to know the hose is available. Spend quite a while trying to remove to no avail. Will cut and remove.

Charles,
Look for a Hydro hose shop in the area they will have compatible hose to use.

Factory Hose/Clamps;


Once you have the hose(s) apart inspect/clean the fitting to assist a proper seal.
Those factory clamps with the Tail/Hook are a gauge to show proper depth of fitting into hose. They also act like a stop when in the correct location hook will rest on raised rim/ring of fitting.

The fitting Jeff shows looks like it has been prepped for the newer reduced barrier hose. My factory ones had very sharp barbs on them. The barbs should be smoothed prior to using modern hose. Also, hose clamps with shielded slots are available so you do not cut into the hose. I got mine from Amazon. I got loose hose off Ebay. There are 3 sizes used on the GTO. All are pretty short except the 5/16 liquid hose coming from the condenser.It has crimped clamps holding it on. You also need a piece of 1/2 and a piece of 5/8. Reduced barrier hose is smaller in cross section than the old stuff. Not sure you can even get the old stuff any more.

Sure can. I ordered 40 feet of it last year.

The factory went back and forth with crimp vs. clamps over the years, I personally crimped mine on the last car I did because I never was a fan of the clamps.

Never new the old stuff was available. Anyway, I think the new stuff may be better. It has a barrier lining like fuel injection hose. I left my 5/16 hose alone as it seemed in good shape and I did not want to go with hose clamps and look too non factory. I researched various clamp types and could not find crimped hoses were any better than hose clamps. With hose clamps one can come back and re torque them as the hose ages. The other type you could use had a spring on them that maintained the torque setting via spring load. They were very expensive though. I torqued mine to 40 inch pounds and will re check them at a later date. I also used the shielded clamps that do not cut into the hose.
