Navigator’s SERPENT flexible connector redefines performance and flexibility in water supply connections. With its all stainless steel construction and liner-free design, this hose provides a clear, unobstructed bore even when shaped to tight angles—perfect for confined spaces or visible installations.
Unlike standard braided hoses, the SERPENT is completely formable and re-formable, allowing installers to shape and reshape the hose without kinking or degrading its integrity. The wipe-clean finish keeps installations tidy, while certifications from WRAS and NSF Regulation-4 confirm safe use in potable water systems.
Every unit is rigorously pressure and leakage tested to BS EN ISO 1086:2003, ensuring consistent performance for both hot and cold water applications. Whether you’re working on a new build, retrofit, or maintenance project, the Navigator SERPENT provides a durable, hygienic, and space-saving solution.
