Every HVAC contractor knows the drill: flare fittings take 10–20 minutes per joint, require a dedicated flare tool, and risk human error — and brazing means open flame, nitrogen purge, and mandatory cooling time. StrongLok™ eliminates all of that.
| Feature | StrongLok™ Union | Traditional Flare |
|---|---|---|
| Install time per joint | ✓ 1–2 minutes | ✗ 10–20 minutes |
| Tools required | ✓ Standard wrench only | ✗ Flare tool + deburring tool |
| Open flame / torch | ✓ Completely flame-free | ✗ Brazing required |
| Sealing mechanism | ✓ Dual O-Ring + Grip-Ring | ✗ Human flare angle/torque |
| Over-torque protection | ✓ Built-in nut stopper | ✗ None |
| Fire permit required | ✓ None | ✗ Often required |
1–2 minutes per joint vs. 10–20 minutes with flare fittings. More jobs per day, every day.
A standard wrench is all you need. No flare tool, no deburring mandrel, no nitrogen purge.
HNBR O-Ring + Grip-Ring locking system rated to 870 psi (60 bar). Gas-tight, every time.
Safe for occupied buildings, server rooms, hospitals — anywhere a torch is a liability.
Mechanical nut stopper prevents over-tightening. 4.5–5.5 mm grip gap ensures consistent results.
Mass-production verified in Samsung and Winnia AC systems. Reliability confirmed at scale.
On a 10-joint mini-split installation, StrongLok™ saves 90–180 minutes of labor vs. flare fittings. At $100/hr, that’s $150–$300 saved per job — before reduced callbacks and zero torch permit costs.
