Stop It® PSX 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 System 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 fiberglass 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.
Set Time: Epoxy – 1 hr; Urethane – Tack free in 3 to 5 minutes; for ambient temperatures of 50°F to 80°F (10°C to 27°C).
Cure Time: 4 hour minimum time. 12 hours for optimum pressure performance. See detailed instructions for breakdown of time.
Pressure Retention: 2500 psi for leaks less than 0.125” od. 500 psi for voids up to 1.0” od (supporting screen required).
Temperature/Heat Resistance: From -20°F up to 250°F (-29°C to 121ºC) – continuous. From 250°F to 500°F (121°C to 260°C) – temporary exposures. If possible, the pipe should be at ambient temperature before application.

Chemical Resistance:
No visible changes in Stop It® after an immersion term of 35 days in the following chemicals:
Potable Water:
Stop It® is accepted for use on potable water lines by the WRC (UK). The Fix Stix Epoxy included with each kit is NSF-certified.
When tested to the failing point in laboratory conditions, failure was indicated by a reduction in line pressure and seepage.
Plant Manager
"Quick and economical fix for leaks that don't lend themselves to clamps. Provides time until a system shutdown allows replacements..."
Jesse Moran, Project Manager
"The stickiness is good for the pipes – it’s not going to let any moisture through. It works really well with stainless steel."
InduMar Client
"Thanks to InduMar's STOP IT® Flat Patch, we were able to repair multiple tanks that had been out of commission, and now they are back in service."
