Hose clamps?

[wantacoe]

Do these three hose clamps have a specific use? I have part numbers but still can not find of them on the internet. 1) Clampco c410c-75-400-s 2) Ideal 300-ss 3) RG Ray 700-30

First and third are probably for clamping turbo intake hoses. The second is typically for clamping exhaust to a turbo.

I've used ones similar to the first and third to hold some rubber sealer type stuff up around a pipe leak before, no idea if that was the actual use for 'em.

Yep. Turbo plumbing. The middle one holds the tube to the turbo and the other two clamp the silicone or rubber to hard pipes. The outer two are " constant pressure"

As already said, they clamp the 2 flanges together, called a v band clamp.

Hopefully the link with the pic works.

The first and third can also be used for hydraulic pump suction line clamps.

The middle clamp has another name (other than v-band) - which I of course can't remember at the moment. Named after the guy who invented them I think. Kind of an interesting history if I recall.

Had to look it up as it was annoying me, Marman clamp.

They are used all over I guess, but mostly I run into them on Mopar exhaust manifolds, Ford turbo diesel trucks (first and second pictured clamp type on those) and sometimes on older industrial gas engines.

First time I encountered them were on military aircraft, an aviation part that was later adapted to automotive. The originals had the T bolt, the one shown is a cheap knock off.

Secured the duct work for the bleed air systems off jet engines.
