7/8" x 3/4" Swage Reducer

7/8"x3/4" Swage Reducer (SWUN7834) - SmartLock Swage Fitting

Join 7/8" swage to 3/4" tubing valve without brazing or flaring. SmartLock SWUN7834 uses patented metal-to-metal sealing technology for permanent, zero-leak joints under pressure. 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 SWUN7834 reducer body
• Two union nuts
• Two ferrules
• One positioning strip

Key Features

• 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.

Compatibility

• Works with all common refrigerants, including R-410A, R-22, R-134a, R-744, R-717 and A2L blends.
• Suitable for 7/8"-to-3/4" copper-to-copper, copper-to-aluminum and aluminum-to-aluminum connections.

Installation & Tools

• 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.
