## Long description

TUCAI spiral hose 400 mm stainless steel with SK to SK fittings is a compact flexible connection hose designed for fluid and gas installations that require corrosion resistance and mechanical strength. Its spiral stainless steel construction provides flexibility while maintaining structural integrity over repeated movements and vibrations. The 400 mm length suits short runs where a durable, compact stainless connection is needed.
Advantages
The spiral stainless steel design combines flexibility with enhanced tensile strength and abrasion resistance compared with smooth-bore alternatives. SK-to-SK end fittings offer standardized, secure connections compatible with systems using SK fittings, reducing the need for adapters. The stainless material resists corrosion from water and common industrial fluids, extending service life in plumbing, HVAC, and light industrial environments.
Suitable for
Short stainless steel connections in plumbing installations
HVAC systems requiring flexible, corrosion-resistant hoses
Industrial machinery connections subject to vibration
Temporary or permanent fluid or gas lines in workshops
Key specifications
Length: 400 mm
Material: stainless steel spiral construction
End fittings: SK to SK
Designed for: fluid and gas applications
Properties: flexible, corrosion-resistant, mechanically robust
How to use
Install the TUCAI spiral hose between compatible SK fittings, ensuring that connection surfaces are clean and free of debris. Hand-tighten the fittings and then apply the appropriate torque if required by the system or installation guidelines; avoid over-tightening to prevent damage to threads or fittings. Check for alignment so the hose is not subjected to excessive bending beyond its natural curvature. After installation, perform a pressure or leak test according to the system's standards before putting the line into regular service.
Usage recommendations
Regularly inspect the hose for signs of wear, kinking, or corrosion at the fittings. Replace the hose if deformation or leakage is detected. Use within the temperature and pressure limits specified by the installation standard applicable to stainless flexible hoses, and avoid prolonged exposure to aggressive chemicals not compatible with stainless steel.
