AST stands for "Advanced Sealing Technologies." AST Mechanical Seals are designed with the springs out of the path of the liquid - unlike all other designs!

AST also markets a magnetic seal that was derived from use as the Main Rotor Seal in the Bell Helicopter. Its use is in sealing the bearing housings of pumps, fans, and other rotating equipment. The AST magnetic seal also has a great application in preventing oil leakage out of gear boxes! If your gear boxes are leaking oil, talk to your Jack Tyler Engineering Representative today!

Moisture in the oil causes most of the bearing failures in rotating equipment today. AST manufactures a Plan 92 Hermatic Sealing System for bearing frames and gear boxes that has been used for years by companies such as Exxon Oil.
