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.

Never received it
Was on back order and I waited just to receive an empty bag from UPS, side was ripped. Called customer service and they're shipping another one from Nevada further from me, thus will take additional week of waiting. I hope they will place them in a box not some plastic bag that rips on the seams.

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.
