Fully certified to ASTM F1387 standards. Bulkhead Union, also known as a through-wall fitting, with double-ferrule tube fitting on both ends. Interchangeable with other major brands including Swagelok and Parker A-Lok.
Manufactured from high quality 316 stainless steel for superior mechanical strength and excellent resistance to corrosion.
Precision machining of components guarantees optimal deformation of ferrules and tubing, providing leak-tight and vibration-resistant connections even in harsh or stressful applications.
Hardened threads with a smooth finish prevent galling, enabling easy assembly and extended fitting service life. Additionally, nut threads are silver-plated to minimize friction against the body threads, allowing for easy disconnection and retightening.
Every FITOK fitting is engraved with details including connection size and type, brand name, material, and heat number, ensuring proper identification, traceability, and quality control.
