Frequently Asked Questions
What is the difference between single ferrule and double ferrule fittings?
Double ferrule compression fittings use two metal rings (ferrules) that work together to create a superior seal. The front ferrule provides the primary seal against the tube, while the back ferrule grips the tube to prevent pullout. This design offers better vibration resistance, higher pressure capability, and more reliable sealing compared to single ferrule systems.
Are double ferrule fittings reusable?
Yes, double ferrule compression fittings are designed to be reusable. Once properly installed, the ferrules conform to the tube surface and can be disconnected and reconnected multiple times without compromising the seal integrity. However, it's important to inspect the ferrules and tube condition before reuse and replace if any damage is detected.
What pressure can these fittings handle?
Our stainless steel double ferrule compression fittings are rated for working pressures up to 6000 PSI (414 bar) depending on the size and configuration. Smaller sizes typically handle higher pressures, while larger sizes may have lower pressure ratings. Always consult the technical specifications for your specific application requirements.
How do I ensure proper installation of double ferrule fittings?
Proper installation involves: 1) Cutting the tube square and deburring, 2) Sliding the nut and ferrules onto the tube, 3) Inserting the tube into the fitting body until it bottoms out, 4) Hand-tightening the nut until finger-tight, then 5) Using a wrench to turn an additional 1-1/4 turns for initial installation. Follow manufacturer torque specifications for optimal performance.
What tube materials are compatible with stainless steel fittings?
Stainless steel double ferrule fittings work best with stainless steel tubing (304, 316, 316L) for optimal corrosion resistance and compatibility. They can also be used with other materials like carbon steel, copper, or specialized alloys, but material compatibility should be verified for specific applications, especially in corrosive environments.
