304 stainless steel double ferrule compression union connector adapter with a wide range of outer diameters (OD) for flexible tube connections. This compact, corrosion resistant fitting is designed to create secure, leak joints in a variety of tubing systems without soldering. Key benefits Leaks prevented by a double ferrule compression design that seals tubing on both ends for long term reliability. No soldering required, enabling quick field installations and easier maintenance. Wide OD compatibility in imperial and metric sizes, increasing versatility across projects. Corrosion resistant 304 stainless steel for durability in demanding environments. Key attributes Material: 304 stainless steel for strength and corrosion resistance. Type: Double ferrule compression union connector adapter. OD range options: imperial sizes 1/8', 1/4', 3/8', 1/2' and metric sizes 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 25, 30 mm. Model reference: adapter (10 mm). Size and compatibility Supports both imperial and metric outer diameters to fit a broad spectrum of tubes. Designed to pair with standard compression fittings and corresponding tubing for reliable connections. The listed OD options should be matched to the tubing used in your system, with the 10 mm size highlighted by the model reference. Material and performance 304 stainless steel provides corrosion resistance and structural strength. Double ferrule design delivers a secure seal under compression, reducing the risk of leaks. Built for durability in plumbing, mechanical, or industrial tubing applications where compression fittings are preferred. How this helps you in practice Quick assembly: compress the ferrules onto tubing to form a tight, leak resistant joint without solder or brazing. Flexible integration: the broad OD options allow you to connect tubes of differing diameters or sections in existing lines without replacing entire assemblies. Long lasting service: stainless steel construction stands up to moisture, chemicals, and temperature variations common in household, workshop, or light industrial settings. Use cases Replacing or upgrading a section of a water or air line that uses standard compression fittings, while accommodating multiple tube diameters. Assembling custom tubing runs in a workshop where different sized tubes must be joined to a single system, without introducing soldering steps. Adapting existing equipment that uses an optional 10 mm line to match other tubing sizes within a single plant or home project. Notes Verify the tubing outer diameter corresponds to one of the listed imperial or metric sizes for a proper fit. Inspect ferrules and the union after installation and periodically during use to ensure continued seal integrity.
