Feature:

 •  Multiple material options & configurations to suit diverse industrial requirements,  
    including high-purity andhigh-pressure applications.

 • Precision-engineered ferrules and bodies provide consistent tube grip and leak-tight 
    performance under demanding conditions.

 • Silver-plated nut threads minimize friction during assembly, ensuring smooth tightening 
    and preventing thread galling.

 • Optimized elbow radius design ensures a streamlined flow path, reducing turbulence and pressure drop.

 • Traceable quality: each fitting is permanently marked with size, material, and heat code for   
    complete identification.

 • User-friendly maintenance: fittings can be easily disconnected and reassembled without loss of integrity.
 • Enhanced durability: hardened threads with a smooth finish extend service life and reduce wear over repeated use.
