Before you order
Twin-ferrule fittings are not cross-compatible between brands. Mid-Lok nuts and ferrules are designed to seal against Mid-Lok bodies. Mixing them with Swagelok, Parker A-LOK or other makes will compromise the seal even where the threads engage, so keep a single brand through any one joint.
Correct make-up matters: these need proper initial pull-up and, on remakes, a gap-inspection gauge. They also require tube of the correct wall thickness and hardness — they will not seal reliably on thin-wall or work-hardened tube.
