Revolutionary New PermaBond process for

hermetically sealed joints

Fab-Tech's PermaBond process eliminates the

possibility of joint leakage with gasket free sealed

joints.

Fab-Tech's PermaBond process provides gasket free joints for 4" to 14" diameter coated PSP® duct.  The process heat bonds the coated flanges of the duct joint together forming a seamless interior surface of PermaBond barrier coating.  Once the joint is cooled, a proprietary PSP-EZ™ clamp is installed for structural support.   PermaBonded duct is sealed to a class suitable for helium leak testing.
