AEP diaphragms are the superior choice. As a primary supplier to major OEM's of truck air brake chambers, AEP has earned an excellent reputation in this highly competitive field. On-time delivery, superior quality and competitive pricing for the past thirty years earned us this position.

Our diaphragms are ARTIC/NYLON, an advanced synthetic polymer blend, which performs with high reliability at temperatures as low as -67 degrees F, more than twice the low-temperature performance of other compounds. Unique bonding and laminating technology gives unusually high abrasion resistance and flex capability (one million cycles) with no delamination.
