TridentSeal® Qualified to New Levels of Performance
After nearly two decades of proven success, TridentSeal® is now even better! Designed for the repair of live leaks in gas distribution lines, the installation parameters have been enhanced to address the latest industry technologies and installation needs. TridentSeal has been tested to perform to these expanded capabilities:
- Increased pressure rating from < 60 psi to <125 psi
- Lowered ambient installation temperature from 32⁰ F to 15⁰ F for cold weather applications
TridentSeal®
Designed to address the need for simple, instant, tamper-proof, live leak repair on gas piping. TridentSeal permanently seals active gas leaks ≤ 125 psi (8.6 bar) without interruption to service.
TridentSeal is easy to install and offers a permanent repair that is guaranteed to perform upon passing a leak test. More than 200,000 repairs over the last two decades without a reported failure upon proper installation.
Each kit repairs one leaking, threaded fitting or pinhole.
BENEFITS
• No customer interruptions
• No relights
• Instant, permanent repair
TYPICAL APPLICATIONS
• Live gas leak repair on:
- Threaded fittings
- Pinholes up to 1/8” diameter
• Above- or below-grade gas
mains, services and meter-sets

These newly qualified standards make TridentSeal an even more efficient and high-performing, permanent repair solution that addresses live leaks and fugitive emissions for a wider range of applications on both above and below ground gas distribution lines.
The TridentSeal repair kit provides a simple, four-step repair that requires no hot work or special tools. The kit includes TridentPutty, which penetrates the defect, seals the leak, and bonds with the piping. A pressure-sealing tape compresses the putty, improving its penetration into defects. Both the putty and tape are then mechanically protected with TridentSeal water-activated, composite outer wrap that cures to a hard finish. Once cured, the system provides a permanent, tamper-proof repair for active gas leaks to <125 psi (8.6 bar) without interruption to service.
While CSNRI has no special training requirements for installation of TridentSeal, we do offer easy-to-follow video and written product use instructions. Training requirements and frequency are subject to the discretion of the operator.
