O-Ring

I've just found out the latest app does not open on my iPod touch running IOS 5.1.1 (earlier ones worked ok) It works fine on my iPad which is running the latest operating system. I can't see any comments that state it wouldn't work on the iPod but even after removing it and downloading it again it's still not opening. Normally apps won't download if the wrong version operating system is running. Does anyone have any ideas? Thanks, John.

Really useful app for specifying o-rings. Almost as good as Trelleborg's superb web based o-ring calculator.

As a mechanical engineer, I find this app very useful. I use it at least once a week. The layout of the app is very easy to work with and intuitive. A must have app for all engineers and for anyone who works with o-rings. Thanks Trelleborg for spending the time on this app.

This is a great tool for quickly calculating o-ring sizes. I've mostly used the "quick search" to determine standard sizes.

This is a great tool for quick answers on the go.

Excellent tool & reference guide. Extensive fluid compatibility chart as well. Very helpful!!

Also good for unit conversion

Great application

Great App! Really like the Material vs. Chemical Compatibility chart.

A great tool to keep you from having to look through pages and pages of catalogs.
