STOP IT® PSX REPAIR SYSTEM
Combines a proprietary epoxy sealant with a durable composite overwrap to accomplish field repair of leaks to systems
with operating pressures up to 2500 psi.
The STOP IT® PSX Repair System derives its high pressure capabilities from the use of a field-mixed, two-part epoxy primary sealant and a fiberglass/urethane composite overwrap.
STOP IT® PSX can be installed by one person with no special tools or hot work, and provides for the completion of in-field repairs and return to service in a total of 4 hours.
Following the cleaning and preparation of the surface, repairs involve the application of a thin film of epoxy sealant from the supplied cartridge gun. Precise mixing is accomplished with the use of a static mixer that is attached to the gun. Once hardened (approximately 1 hr), the sealant is overwrapped with a fi berglass tape impregnated with water-activated polyurethane resins. Systems may be returned to service at pressures up to 2500 psi as soon as 4 hours following the application of the epoxy.
Stop It® PSX can be used almost anywhere – including underwater and in chemical and military facilities – to repair chemical, steam, process and water lines.
STOP IT® PSX Is Ideally Suited For:
• Routine and emergency high pressure leak repair
• Sealing joints
• Rebuilding thinning wall in high pressure piping
• Repairs in hard to reach areas
• Underwater repairs
• Large scale defects (Voids up to 1.0” od repaired to 500 psi)

Safety Features
Even under extreme pressures, the Stop It® Pipe Repair Tape will not shatter or crack. Stop It® releases pressures slowly.
When tested to the failing point in laboratory conditions, failure was indicated by a reduction in line pressure and seepage.
