## Long description

TUCAI stainless steel spiral hose 300 mm SK/VK model 1863 is a flexible metal hose designed for fluid and gas transfer in compact installations. The 300 mm length and spiral construction deliver mechanical strength and flexibility while stainless steel construction provides corrosion resistance for use in domestic and industrial environments. The SK/VK connection designation indicates compatibility with standard fittings used in plumbing, equipment connections and HVAC systems where a durable, flexible metal link is required.
Advantages
The spiral stainless steel design combines flexibility with high mechanical strength and abrasion resistance, reducing the risk of kinking in confined spaces. Corrosion-resistant stainless steel ensures long service life in wet, humid or chemically aggressive environments. The compact 300 mm length is suitable for tight routings and provides a reliable, durable connection between equipment and piping without relying on rubber or braided alternatives.
Suitable for
 Compact plumbing connections between appliances and water or gas lines
 HVAC system connections requiring corrosion-resistant flexible hoses
 Industrial machinery where a short, durable flexible connection is needed
 Environments with moisture or mild chemical exposure
Key specifications
 Material: stainless steel spiral construction
 Length: 300 mm
 Connection designation: SK/VK compatible fittings
 Design: flexible spiral hose for fluid and gas transfer
 Typical applications: plumbing, HVAC, equipment connections
How to use
Install the TUCAI spiral hose between compatible SK or VK fittings following the system's thread and sealing requirements. Ensure both connection surfaces are clean and correctly aligned before tightening to avoid cross-threading. Hand-start the fittings and then tighten with appropriate tools to the torque recommended for the mating fittings; avoid over-tightening which can damage threads or the hose end fittings. Verify the assembly for leaks under low pressure before returning the system to full operating pressure.
Usage recommendations
Use the hose within the temperature and pressure ratings specified by the installation standards for stainless steel flexible hoses. Inspect periodically for signs of wear, abrasion or damage, especially in areas with movement or vibration. Replace the hose if permanent deformation, corrosion or persistent leakage is detected. For gas installations follow applicable local codes and use appropriate thread sealants or gaskets as required.
