Swagelok® Tube Fittings and Adapters
Reduce leaks and downtime with two-ferrule tube fittings that have leak-tight seals, superior tube grip, and vibration resistance, even after reassembly.
Tube Fittings | Easy to install helping to reduce installer fatigue.
Tube Adapters | Enable various connections and help eliminate difficult alignment issues.
Swagelok fittings outperform others in reducing the risk of leaks and costly downtime across various industries. The advanced back ferrule design isolates stress to resist vibration, bending, and deflection, while a patented carburization process enhances strength without sacrificing corrosion resistance. Easy to install and reassemble, Swagelok fittings require less effort than alternatives.
Tube fittings and adapter fittings are available in multiple alloys to ensure chemical compatibility, with expert-led training offered for proper installation. Swagelok tube adapters can be used with any other Swagelok tube fittings eliminating the need for stocking special elbows and tees. Stainless steel Swagelok tube fittings used with 316 stainless steel and 316 Ti stainless steel alloy tubing have been tested to the requirements of ECE R110 and are also available with EC-79 certification. Swagelok offers fittings in materials that meet the metallurgical requirements of NACE MR0175/ISO 15156 and MR0103. Also, fittings manufactured from alloy 2507 and 6MO are NORSOK M-630 and M-650 compliant as standard.

Comment les adaptateurs pour tubes peuvent éliminer des problèmes d’alignement
Les adaptateurs pour tubes peuvent aider à résoudre des problèmes d’alignement délicats, tout en réduisant le nombre de composants à garder en stock. Regardez comment utiliser des adaptateurs pour tubes Swagelok® pour résoudre des problèmes d’alignement tout en créant des raccordements étanches.
Depuis 1947, Swagelok est à la pointe de la technologie des raccords pour tubes utilisés pour les systèmes fluides industriels dans presque tous les secteurs d’activité.
Le fondateur de Swagelok présente son raccord pour tube révolutionnaire
Plus de 75 ans plus tard, le raccord pour tube Swagelok, avec son action unique de « sertissage-articulation », reste un produit réputé pour l’étanchéité et la durabilité des raccordements qu’il permet de réaliser. Grâce à cette double action, on obtient des performances optimales dans trois domaines essentiels :
Le maintien du tube
L’effet d’articulation et de sertissage permet un contact plus direct avec le tube et une meilleure accroche.
L’étanchéité aux gaz
L’effet de brunissage/polissage de la bague avant crée des zones de contact concentrées sur le tube et la partie biseautée du corps pour former un joint plus efficace.
La résistance aux vibrations
La zone de sertissage limite la concentration des contraintes au niveau de la surface d’accroche pour que le tube résiste mieux aux effets de la flexion, de la flèche et des vibrations.
La conception des raccords pour tubes Swagelok®
La bague arrière – avec son action de sertissage-articulation et sa géométrie avancée – équipe de manière standard tous les raccords pour tubes Swagelok en acier inoxydable de 1/4 à 1 po et de 6 à 25 mm, favorisant ainsi la réalisation de raccordements étanches par les installateurs. Pour ces dimensions, un procédé de durcissement superficiel breveté et une géométrie évidée et profilée brevetée confèrent une technicité unique à la bague arrière Swagelok. Le modèle de bague arrière à action de sertissage-articulation améliore les performances déjà élevées du modèle traditionnel de bague.
