Potable Water Certified
WRAS & ACS certified for use in potable water applications, supporting safety and compliance requirements for drinking water systems.










WRAS & ACS certified for use in potable water applications, supporting safety and compliance requirements for drinking water systems.
Manufactured from high-quality PTFE for clean, stable sealing performance in potable and industrial water systems.
Engineered to maintain thread sealing stability under sustained pressure and help reduce creep and extrusion.
Suitable for threaded connections in copper, brass, stainless steel, galvanized steel, PVC, PPR, and other common piping materials.
Provides an immediate mechanical seal without curing or drying, helping simplify installation and pressure testing.
PTFE provides excellent resistance to temperature cycling, chlorinated water, and many commonly encountered water-treatment chemicals.

| Comparison | General-Purpose PTFE Tape | Foreverseal® Aqua |
|---|---|---|
| Design Focus | Designed for general threaded sealing applications. | ✔ Engineered specifically for water system thread sealing. |
| Sealing Stability | Performance varies depending on tape density, thickness, and installation. | ✔ Optimized density and structure for consistent sealing under water pressure. |
| Potable Water Compliance | Certification varies by product and manufacturer. | ✔ WRAS & ACS certified for potable water applications. |
| Material Quality | Material grade and manufacturing consistency vary by product. | ✔ Manufactured from 100% virgin PTFE with controlled specifications. |
| Long-term Reliability | Performance depends on material quality, system conditions, and installation. | ✔ Designed for long-term sealing stability under pressure and temperature cycling. |
When the fitting is tightened, the PTFE tape conforms to the thread profile and compresses into microscopic gaps between the male and female threads. This helps create a reliable seal while also reducing friction during assembly.
Engineered for Long-Term Water System Reliability
Reliable thread sealing depends on more than initial installation. Foreverseal® Aqua is designed to maintain sealing stability under pressure, temperature cycling, and changing operating conditions.
Consistent sealing performance. Reliable water system connections.

Discover how Foreverseal® Aqua is designed for reliable threaded sealing in potable water, plumbing, HVAC, and other water systems, with controlled PTFE specifications and potable-water compliance options.
