Below you will find a list of our most commonly stocked pull-stubs for use with our PATTI line of adhesion testers. Most customers use our standard 1/2" diameter pull-stub. We recommend these because research has shown that as the stub diameter increases, more substrate bending can occur.
That being said, there are circumstances that warrant using a larger (or smaller) diameter pull-stub (for example, testing coatings on concrete.) We have several different machinists that we can work with to provide you with the exact stubs you need for your application, even if what you need is not listed.
Some examples of specialty stubs that we've created for customers include stainless steel stubs for soldering onto a substrate and curved face stubs with a radius to match a given size pipe.
