Looking for hose clamps

[IamScotticus]

Hi,

has anyone found a source for spring type radiator hose clamps that are shiny like cadmium?

I will be using Samco hose.

Also looking for the same type clamps for fuel hose, they're easier to find.

Just a thought for anyone thinking about silicone hoses. They require a special clamp design. The old ones used before silicone can dig into the silicone. The proper clamps for silicone must have a smooth,flat surface clamping onto the silicone all the way around. As with so many polymer applications, there are correct choices and designs that prevent problems. In the past I have seen way too many misapplications where choosing the slightly more expensive plastic or rubber makes a huge difference in reliability.

Yes, I am open to finding the proper clamp, particularly one with expansion properties.

The Samco supplies stainless worm gear type clamps.

I have heard of rolled/raised edge hose clamps but none are constant tension.

One of the reasons hoses get cut is from the sharp edges on clamps that do not expand.

Then when the hose is dried out from repeated compression,  they leak.

I hope the silicone Samco hose is more resilient.

I can put a radius on a square clamp edge if I have enough material.

I bought these from Summit and they work very well.

Pegasus also has some that work well for silicone hoses: https://www.pegasusautoracing.com//productselection.asp?Product=3613

 

 

I've also had good experiences with the Summit style that @toldfield shared above.

I have the sleeved ss clamps shown above on my car for 5 years now with absolutely no issues. When I have had occasion to loosen and remove them, there has been no underlying damage. I simply reinstalled them in the same orientation. Pegasus does (or used to) offer molded rubber covers for the exposed end of the slotted band. They definitely help in reducing the injury potential when working in proximity tooth hoses. (best seen at the angled juncture aft of the radiator inlet)

I think the only hose clamps on my car are on the air filter, I will not use them anywhere else. If a joint is never going to come apart under normal maintenance I use an Oetiker clamp, If the joint will come apart for maintenance I use spring clamps. I have a pair of spring clamp pliers that make handling them easier. 

 

If your going to use hose clamps you should use needle nose pliers and curl the loose end of the band down. I have seen some nasty cuts from the loose ends.
