Delivering high performance under high pressure

For more than 60 years, Danfoss has provided innovative Synflex hose products for subsea applications. Our engineers are experts in understanding material properties and solving technical problems. Synflex bundles are built to meet and exceed the most demanding requirements, including API 17E and we specialize in producing long continuous lengths of subsea hose.

Synflex high pressure hose

From the beginning, Synflex has been synonymous with quality and innovation. At its core, Synflex High Pressure Hose is a smooth, seamless, continuous extrusion of Nylon 11 Besno P40 TLO. The hose is reinforced with premium aramid fiber and jacketed with a highly UV resistant thermoplastic for long term aging and resistance to hydrolysis. Long continuous lengths are available for subsea bundles and single line applications.
