A Critical Reminder: Conducting pressure testing poses significant hazards, demanding strict adherence to safety protocols. Ensure all connections, valves, flanges, and fittings are suitable for pressure testing. Verify the compatibility of line ID & Plug Range. Most importantly, never position yourself in front of a test plug or enclosure during testing. Discharge from a plug during testing could result in severe injury or fatality.
ISOLATION/TEST PLUGS VS. WELDING END-CAPS
Isolation/Test plugs deliver faster turnarounds, lower costs, improved safety, and greater flexibility than welding end caps on pipe spools—transforming pressure testing from a bottleneck into a streamlined operation.
THE COMPARISON
GSST Isolation / Test Plugs
RecommendedWelding End-Caps
Legacy MethodWHY PLUGS WIN
Faster Turnarounds
Eliminate welding and grinding time. Go from installation to pressure testing in minutes, not hours—keeping your project schedule on track.
Lower Total Cost
Reusable plugs replace single-use caps, welder labor, consumables, and post-weld inspections. The ROI is immediate and compounding.
Improved Safety
Zero hot work means no fire watches, no arc flash risk, no fume exposure, and no hot work permits. A fundamentally safer process.
Greater Flexibility
Quickly adapt to changing test configurations. Reposition plugs across different spools and pipe sizes without rework or waste.
THE BOTTOM LINE
Isolation/Test plugs transform pressure testing from a bottleneck into a streamlined operation—delivering speed, savings, safety, and flexibility that welding end-caps simply cannot match.

Frequently Asked Questions
Typically not on our canvas plugs, but we can provide a different style that does have vent through capabilities.
We have provided inflatable pipe plugs up to 66". If you need a larger size we can provide other solutions for you!
Yes, let us know what size hose you need.
Our inflatable pipe plug is available in heat resistant materials that can be safe for use up to 200°F.
Although they can hold a few pounds, we do not recommend these be used for holding back pressure unless it's for water and there would be a negligible impact if they failed.
The only thing that can be repaired is the valve stem inner fill stem.
