Did Ford only use the flat band hose clamps that are currently sold by the vendors? Iíve never really liked them. They seem to distort just at the point where they are tightened enough to stop the hose from leaking. I prefer the function and look of the double wire type.
Mark- I think the clamps from the vendors don't work properly because the modern hose is way stiffer than the OE stuff from back in the day. I suspect that original hose material was soft and pliable rubber.
I have seen the original hose rubber and it was hard as a rock.
Some folks install their hoses initially with modern worm-style clamps. Once the hoses have taken a set and sealed to the tubes, then they remove the modern clamps and install the reproduction clamps to get the correct look.
It seems the gauge of the metal and/or the metalurgy used for the reproduction flat band clamps available today is not quite as heavy as the originals. I have had the same experience as Mark describes, while I have had some original clamps that seem way more robust and resistant to distortion.
Bob- you must have a time machine...
When I restored my '25 about ten years ago, Snyders claimed they had hose clamps just like Henry made'em. I ordered a set, and they were not! I complained about it, and it turns out they had them for Model A's, but not T's! So, for $20 more I bought the A set. Maybe they have corrected the problem by now.
The repro clamps are made wrong, the narrow interior sliding tab goes outboard, the wrong way, pulls away from the hose as the screw is tightened, so there is way less clamping at the focal point of the clamp screw.
Arrow notes correct place for the narrow sliding tab, under the clamp screw, so that the tab is pushed over firmly on the hose.
And the repo appears to have about half the material in the band and screw compared to the original, which obviously reduces functionality.
That can be partially corrected by turning the screw around ?More importantly, note the difference in the gauge of metal and the size of the fastener between the repro and the original. The repro is like a movie prop - looks good on film, can't serve the duty. Too much repro stuff is like this.
There's another issue with this type of clamp - they need to be the correct size, within fractions. I found some NOS clamps at a surplus store, thought I'd cut a fat hog, but they were not quite the right size and didn't work on my T.
Re/ Mark's reference to similar clamps made with a double wire, I'd reckon they are "period correct" and I've had good results with them over years.
Very interesting guys. That comparison of a new to vintage clamp is really telling. Looks like I have something to put on my search list for Hershey this year. I also like Mikes description f using a modern clamp and switching out after the hose has been compressed for awhile. For now ... I'm still using some NOS wire type clamps.
I don't have a time machine, that is why the original rubber hoses I have seen were hard as a rock!
I have heard of people putting sealer on the outlet then the hose with a modern clamp and then later replace the clamp with the reproduction type so it looks right and is sealed.
Where can you find the double wire clamps?
Here is an eBay listing of some old clamps including the wire type one others for comparison.
When fitting the radiator to Henrietta, I used the original clamps on the side tube. I replaced the bolts and square nuts and used Permatex no 2 gasket cement to help them seal. No such luck. I think the problem lay in the replacement hoses being thinner in the wall. They pinched into a little mound between the ears on the clamps. The hoses I had removed were considerably thicker in the wall, and consequently were not likely do the same.

I hope Snyders has corrected the problem. It also upsets me that they claimed that the hose clamps they had were just like Henry made them, when they were not! Ideal made the exact hose clamp until recently. I don't know why they would have dropped a popular part?
I've been to quite a few swap meets and don't recall seeing original hose clamps that were NOS are good used originals.
I wasen't really looking for them maybe.
Looks like the NOS clamps will a highly looked for Item at swapmeets now.
I wonder if the "show quality" Model A hose clamps would be a closer match:
While sealer will work, I use grease instead. The other thing is, if the block outlet and inlet are deeply pitted, clean and fill the pits with JB Weld and sand smooth before you paint and install.
Snyders does in fact make the correct hose clamps now. I don't know if they have moved them over to the T side of their catalog, but when I ordered mine, I had to order the Model A clamps which were around $30 for a set.
if the Model A Clamps are the same as T clamps these are available from Bert's in the Denver area.
