Re: 1967 a/c hose clamps

After some research I have concluded that for 1967, the clamps used for the PCV and power brake hoses looked like the one in the attached photo. Apparently these clamps evolved over time, with the earliest versions having three squared tangs, then this version with one round and two "half-round" tangs, and the finally a version with all three tangs rounded.

The version with all three tangs rounded is available in reproduction. The version in the photo below sometimes shows up on ebay.

Regarding the Murray A/C clamps, I can take a photo if you need to see what they look like. They say something like "Murray Gold Seal, Towson, MD." My guess is that all GM A/C cars of the period used these clamps, so they are probably not a Corvette-only item. I do not know if these are available in reproduction.

Joe,

I'm not sure about the timeline of the PCV PB hose clamps. I have a known original PCV hose and clamps from a late 65. It has the half round ends and the round center tab as shown in your picture. Based on this and a few others, I believe this version came first followed by the square tang version. Not sure where the all round tab version fits in the timeline.

Hi Don:

You may be correct. I had the impression that the evolution was from square to round, but I could be mistaken.

Lou - It's still smokey as far as I can see because the "Subject" line is "A/C hose clamps" and you're taking about Murray hose clamps (who made some of the '67 air conditioning hose hose clamps and all of a sudden you're on to p/b and pcv hose clamps. As you can see, folks want to help but please clear the smoke. Pete

Hi Lou:

As promised, here is a photo of a Murray A/C clamp from my April 67 car. A key characteristic is the "locator arm" that is just visible on the right. This arm is to be placed so that it hooks over the end of the hose. That helps to precisely locate the clamp position in the intended area of the metal pipe inside the hose.
