Description
xPremium sealing power with PTFE-enhanced Slic-Tite
La-Co Slic-Tite is a premium thread sealant paste formulated with PTFE for strong, reliable sealing of threaded connections. For decades it has helped technicians seal joints across water, air, steam, natural gas, and more, while cleaning up easily from skin and clothing after the job.
What it covers
- Compatible with metal, PVC, CPVC, and ABS pipe threads
- Seals water, air, steam, natural gas, LP gas, refrigerants, ammonia, gasoline, ethanol, and oil
- Designed to perform in high-pressure systems
Tip: For best results, apply to a thickness of at least twice the depth of the thread root to ensure the joint fills with sealant.
Performance and standards
- Pressure resistance: up to 3,000 PSI for gas and 10,000 PSI for liquid systems
- Temperature range: -50°F to 500°F (-45°C to 260°C)
- Comes with approvals to meet industry standards
Product design and usage tips
- 1/2 pint jar with brush-in-cap for easy, controlled application
- Suitable for tapered threads (ANSI/ASME NPT, BS 21 BSPT, AS 1722.1 RC/R)
- Paste washes off hands and clothing, reducing post-job cleanup time
Real-world scenarios include sealing pipe threads in water lines, compressed air runs, steam lines, and gas piping in both residential and commercial settings. The paste’s consistency helps it stay where applied, while the cap-brush design supports quick, tidy coats. Consider Slic-Tite as a dependable option when you need a ready-to-use sealant that delivers strong performance under routine, demanding conditions.
