Premium White Sanitary Hose (Anti-Odor PVC with Steel Spiral) – Ø20, 25, 38, 40 mm

The Osculati Premium sanitary hose represents a top-tier solution for plumbing and waste systems on vessels. This hose is specifically engineered with problematic onboard areas in mind – toilets, pumps, drains – where ordinary hoses might fail. The white color gives it a more attractive look and makes it easier to spot any soiling or changes, and the material’s anti-odor properties mean foul smells won’t seep through the walls.

Construction and Technical Advantages:

• Odor-Shield PVC: The special PVC formulation ensures minimal “sweating” of the hose (i.e., no surface condensation and no odor escape). Even when carrying sewage or gray water, the hose keeps the smells contained. This is crucial for long hose runs in a yacht – for example, from a toilet to a holding tank located far away – the entire run remains neutral to the surrounding air.
• Embedded Steel Spiral: A key feature is the reinforcing steel spiral embedded within the hose wall. It allows the hose to be highly flexible yet maintain its shape when bent. This means the hose won’t kink or flatten if routed around a tight radius. The steel reinforcement also greatly increases its resistance to internal pressure (rated up to 4–5 bar depending on diameter) and vacuum (when used on the suction side of a pump). For instance, if used as a bilge or sewage pump suction line, it won’t collapse under suction.
• Wide Temperature Range: Certified for use from -15°C to +60°C (5°F to 140°F), covering all normal operating conditions. At -15°C, the hose remains sufficiently elastic (it won’t crack if accidentally bent), and at +60°C it won’t overly soften or leach odors. This makes it suitable for both cold and warm waste water (for example, from showers or galleys).
• Available Sizes & Uses:
  • Ø20 mm: Serves smaller connections – for example, draining water from sinks or showers (gray water) where a reliable, leak-proof hose is needed. It can also be used for carrying condensate from air conditioning units or other drain lines.
  • Ø25 mm: Fits some pump models or special fittings. It can act as a general-purpose size to connect traps and fittings on smaller boats if 38 mm is too large.
  • Ø38 mm: The standard size for toilet waste hoses and holding tank pump-out lines. This hose is a perfect drop-in upgrade for standard 38 mm sanitation hoses – the same diameter but significantly improved flexibility and durability. If your current setup suffers from odor issues or difficult installation due to stiffness, swapping to Osculati Premium Ø38 mm can solve both issues.
  • Ø40 mm: A slightly larger size that may appear in certain European installations or specific pumps. If your system has 40 mm fittings, having this size option means you can enjoy the premium quality without reducers. 40 mm is also sometimes used for deck drains or specialized valves.
• Longevity and Value: While this premium hose is a higher upfront investment, it pays off with a longer service life and fewer troubles. You won’t need to replace it often due to hardening or odor seepage. Additionally, thanks to its material resilience, the risk of sudden ruptures or leaks is minimized – which is priceless on the water. Vessels equipped with this grade of hose benefit from easier maintenance and higher resale value, since these components greatly contribute to onboard comfort and safety.
