ULTRASEAL TEAMS WITH THE U.S. POSTAL SERVICE TO ESTABLISH FEDERAL SPECIFICATION FOR MINIMUM TIRE SEALANT PERFORMANCE

Postal Vehicles 1In 1993, representatives from GSA, EPA and the U.S. Postal System established a Generic Tire Sealant Specification that set the world’s first standard for tire sealants. Safety, compatibility and performance (minimum 20,000 miles) were the basic requirements for a new/unused tire sealant. The specification also required safety and compatibility re-testing of the used tire sealant, upon completion of the 20,000 miles. With the approval of the U.S. Postal Service, Ultraseal International contracted with the testing facility to have the performance portion of the test extended to 40,000 miles.
