Uni-Spray was called in to a major brewery in Canada to assist in solving a major problem they were having with glass inclusion. What we discovered is that the seals they were using were sub-standard after-market seals. They agreed to test our TPU seals and have successfully reduced glass inclusion to manageable occurrences. We were able to match the price on our seals to what they were paying and they now replace seals every two weeks as opposed to every week with the old seals, saving them time and money as well as virtually eliminating the very serious problem of glass inclusion.
