One thing to mention. You test each and every CAT to 30-40 psi for leaks but...they operate under suction. The difference between suction and pressure could result in different results.
I only mention this because I work for a plastic closure company and find big differences between testing for pressurized product and product that may draw a vacuum in regards to leak testing.
