Will these clamps work on auto radiator hoses?

Yes, very well, with a caveat. These clamps are 3/4" wide and the radiator I wanted to use it for has less than 3/4" length from tank to barb. In this case the clamp would be rubbing on the tank and over lap the barb. If I had 7/8" to 1" flat I would have stayed with this T-bolt clamp. Instead I opted for a 1/2" wide worm gear lined clamp.

Solid pipe is 2.20 " od with digital caliper. hose to go over pipe is 2.22"id. outside of hose is 2.55. which clamp is gonna fit tight?

You should select T clamps based on Hose OD 2.55" = 64.8mm, we suggest to use 2.25" t bolt clamps with the working range at 64mm - 71 mm. thank you!

How would these work on a 2" water suction hose on my gas powered water pump? Honda WX20.

Hello, Dear Linda, Please check your hose OD diameter and make sure it is in the working range. Usually 2" Water hose means its' ID size is 2", but the thickness in different standard is much different, it leads the OD is much different accordingly. Please select appropriate T Clamps based on your OD size. Thank you and have a nice day today. Thank you to consider buying from us: Roadformer Best Regards, Roadformer Products
