Titanium hose clamps

Found these while randomly browsing the web, titanium hose clamps!

Titanium Hose Clamps

I haven't used them, and am not associated with them, and never heard of titanium hose clamps before. Cheap too if it saves weight, but probably doesn't save much weight.

Save at LEAST a dram or two !

I've busted a couple of hose clamps for the intercooler... I could see these as being a bit of insurance.

neat but I think you'd save more weight by pooping

If it's stuff like that use a v-band clamp lots of the import guys run those so they hold 20+lbs off boost good

If you want clamps that hold properly have maximum clamping, and don't damage the hose that they are clamping, then try the "T-bolt" type in the first photo. If you are looking for hose clamps for coolant lines and/or vacuum lines use spring clamps (second photo) as the work best. Try to avoid the typical "screw clamps" (like the titanium one in the link) as they tighten in one area (kind of pinching the hose), and they don't hold a constant clamping force.

The hoses and fittings expand and contract from heat and cold cycles. Additionally the rubber of the hoses tend to "creep" a bit (get thinner under the clamps) from the clamp compressing on the rubber hose. The spring type of clamp applies a constant amount of clamping force - as things get hotter and expand, the clamp expands but still holds with the same amount of force. The opposite when thing cool.

Titanium is a great material but it is NOT a solution to all problems. Titanium has poor notch resistance so it is very bad for bolts or clamps, unless you are prepared to change them out often. In other words, it is not for us but for F1 and the aircraft induxtry.

Common Titanium myths:

1. Titanium is stronger then steel. It is not. the only material stronger then steel per unit weight is Magnesium and Carbon fibre. Now, there are many types of steels; mild, chrome-moly, maraging stainless.... Titanium bolts are Grade 5, chrome moly is Grade 8 on SAE scale. Titanium does not loose as much strength, as rapidly as steel at high temperatures, so here it has definite advantages.

2. Titanium is very rare. In fact Titanium is very common on earth. Some beaches (sand) in Chile are 44% Titanium in the form of Titanium Oxide sand. Processing and refining is very expensive.

I prefer unobtanium for all applications

Did it sound like a BOV when when the clamp broke?

On my car, at about 5k RPM it would hear a BOV-like "whoosh!" LOL

damn those are expensive.

Wikipedia says you're wrong. (and we all know wikipedia is never wrong)
it's strength to weight ration is way better than steel. But due to it's low density it's strengh to volume is probably not.
Thus if bolts were of the same size, then Titanium would be weaker. But if bolts were of the same weight, titanium would be strong, but larger.

Titanium - Wikipedia, the free encyclopedia
The two most useful properties of the metal form are corrosion resistance and the highest strength-to-weight ratio of any metal.[5] In its unalloyed condition, titanium is as strong as some steels, but 45% lighter.[6] There are two allotropic forms[7] and five naturally occurring isotopes of this element; 46Ti through 50Ti, with 48Ti being the most abundant (73.8%).[8] Titanium's properties are chemically and physically similar to zirconium.

Back when I was in college, I worked at a titanium foundry for a few months - they made landing gear struts, fins for missiles, and of all things, bicycle parts.

I have two pieces of titanium from that job; on is a bit of "flash" from the mold line, the other is a part of a bicycle brake linkage. The flash is very thin and a couple of inches long (about as thick as a tin can lid) - I have yet to find anyone that can bend it. The bicycle part is a curved piece about 3 inches long with a flattened part and hole on each end. It about 1/8 inch thick. No one has been able to bend it either.

stainless steel hose clamp will eventually rust and fail

Stainless doesn't rust.

Titanium works exceedingly well in both applications. I've used Titanium hose clamps in many applications (generally small hose or confined areas where a t-bolt won't work) and have yet to have one fail. They're much easier to work with than stainless worm clams, which are trivial to strip.

1. Titanium is stronger then steel. It is not.

Yes, by weight, it is. While some very high grade steel alloys have a higher tensile strength than titanium, they weigh a hell of a lot more. Pound for pound, titanium is stronger, though the principle advantage is having to use less of it to make a part of equal strength to a steel part.

Yes! That's exactly what it sounded like.....REALLY loud.

Titanium is NOT stronger than steel in absolute terms. Chrome Moly is good to 220,000psi.

Titanium is NOT stronger then steel by weight. I refer to 'Prepare to Race'
by Shelby Smith. The only thing that has higher tensile strength than steel i.e. tensle strength divided by density is mignesium and carbon fibre in tension.

The rod bolts I use are 315,000 psi, CP titanium is about 80,000 psi, 6AL4V can get to 200,000 psi. I think there is more to it than that - hardness, fatigue life, corrosion resistance, yield, modulus all are important factors too. Something which most people overlook is operating temperature - 7075 on paper looks good, but at any temperature above ambient its strength decreases sharply.

On the original subject I find the constant clamp (like OEM) hose clamps perform best - the worm type as pictured are not very good. Otherwise there is a diesel truck place which sells stainless T clamps for $1-$2 apiece.

Stainless rusts just great in a saltwater environment.
I could really use some non rusting hose clamps for some of my aquarium projects. I have not been able to find plastic clamps large enough for some of the plumbing.
I'll try some. If they really don't rust, I will be surprised.
Have seen gold last a long while in saltwater though.
