3/4" Swage Union (SWUN3400) - SmartLock Swage Fitting
Connect 3/4" copper or aluminum tubes to swage valves without brazing or flaring. SmartLock SWUN3400 uses patented metal-to-metal sealing technology for permanent, zero-leak joints under any pressure or temperature. Standard wrenches align and tighten components automatically, letting technicians skip open flames and finish installs faster.
What's in the Box (pre-assembled)
Connect 3/4" copper or aluminum tubes to swage valves without brazing or flaring. SmartLock SWUN3400 uses patented metal-to-metal sealing technology for permanent, zero-leak joints under any pressure or temperature. Standard wrenches align and tighten components automatically, letting technicians skip open flames and finish installs faster.
What's in the Box (pre-assembled)
- One SmartLock SWUN3400 union body
- Two union nuts
- Two ferrules
- One positioning strip
- No brazing or flaring required. Tighten nuts to seal tubes and valves without heat or flame.
- Automatic alignment. Positioning strip holds ferrules and body in perfect alignment for smooth assembly.
- Metal-to-metal seal. Compression ferrules deform to seal under high pressure for lasting, leak-free joints.
- Over-torque prevention. Built-in stops prevent nuts from overtightening and damaging the fitting.
- Corrosion-resistant finish.
- Works with all common refrigerants, including R-410A, R-22, R-134a, R-744, R-717 and A2L blends.
- Suitable for copper-to-copper, copper-to-aluminum and aluminum-to-aluminum connections.
- Tools needed. Standard open-end or adjustable wrenches only.
- Installation tip. Hand-start nuts on tubes and valves, then wrench-tighten until the fitting's torque stop engages.

A little tight on the swage
The swage end was farily hard to get on, but did go eventually with some persuasion. Better than their 7/8 swage products, but no where near as easy as the 3/8 stuff.

My ac unit
Been a heavy equipment mechanic for 40 years have done ac on cars and trucks. When my central ac unit went out I called 2 places and never got a call back I found an older but brand new replacement unit and installed myself. Seeing how crude brazing the lines is o knew there had to be an easier way so I bought the fittings and they are a breeze to install.
