7/8" Union Straight (UNST7800) - SmartLock Compression Fitting
Join 7/8" copper or aluminum tubes without brazing or flaring. SmartLock UNST7800 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 jobs faster.
What's in the Box (pre-assembled)
Join 7/8" copper or aluminum tubes without brazing or flaring. SmartLock UNST7800 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 jobs faster.
What's in the Box (pre-assembled)
- One SmartLock UNST7800 union body
- Two union nuts
- Two ferrules
- One positioning strip
- No brazing or flaring required. Tighten nuts to seal tubes 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, then wrench-tighten until the fitting's torque stop engages.
