Can anyone confirm that the McMaster part is equivalent to the amazon link for the spear gun tubing (other than the dimensions) in terms of quality or rubber type?
We ran the McMaster tubing at our first competition and it definitely showed some wear and caused some issues in eliminations, I am wondering if the spear gun tubing will be better.

I can't verify that they are the same as we haven't gotten the amazon stuff but they are both latex rubber. So can't be much different. What size did you try from McMaster?

There are many variables to what causes wear, such as attachment points and stretch %.

I bought both the 'Spear it' brand spear tubing, and McMaster Latex Tubing and they appear to be identical, at least for our purposes.

Specifically, we've used both 12mm (1/2") Spear-it tubing, which seems to be identical to 1/2" OD, 3/16" wall latex tubing from McMaster.

Re: Surgical tubing stretched too far

Another option, we went with the fitness bands. Find the force and corresponding diameters that work for your application and have fun. Our experience was a band reached its "advertised" force at approximately twice its original length. The brand carried by the chain sporting goods stores around here sells them in increments up to 100 lbs.

Re: Surgical tubing stretched too far

We are very happy with the 'KOP' linear force springs from Vulcan

Hundreds of shots, no change.
