Key Features and Benefits
- Innovative Poseidon Sealing System: The patented “Balance Sealing System Poseidon” guarantees maximum joint integrity. The gasket compression force self-adjusts precisely around the pipe during nut tightening, eliminating leak risks even on scratched or uneven surfaces.
- No-Dismantling Installation: A specially profiled conical gasket allows the pipe to slide directly into the body without needing to undo or fully disassemble internal components. This cuts installation time by over 50%.
- Superior Material Quality: The body and nut are engineered from virgin polypropylene (PP-B) for exceptional mechanical strength. The high-performance polyacetal (POM) split ring firmly anchors the pipe, preventing pull-out caused by water hammer events.
- Full Weather Resistance: The polymer is 100% stabilised against UV radiation (Class 8 per ASTM D2565), frost-resistant, and chemically inert against liquid fertilisers and chemicals commonly used in commercial horticulture.
