Unipak Univlies pipe cleaner for copper pipes is a specialized cleaning agent designed to remove oxidation, flux residues and surface contaminants from copper plumbing and refrigeration lines. Formulated for use prior to brazing or soldering, this cleaner improves wetting of filler metals and supports formation of reliable, leak-resistant joints. The product is intended for professional plumbers and HVAC technicians working with copper tubing and fittings.

Advantages

This Univlies pipe cleaner penetrates and dissolves oxides and residues without excessive mechanical effort, reducing preparation time before joining copper parts. The formulation is compatible with common fluxes and does not leave films that inhibit solder flow when applied according to instructions. It supports consistent joint quality, aids in preventing voids and cold joints, and helps maintain efficiency in professional plumbing and refrigeration workflows.

Suitable for

• Cleaning copper water and gas plumbing pipes prior to soldering or brazing
• Preparing refrigeration and air-conditioning copper lines for brazed joints
• Removing oxidation and flux residues from fittings and tubing during maintenance

Key specifications

• Type: liquid pipe cleaner formulated for copper surfaces
• Primary function: removal of oxidation, flux residues and contaminants
• Application area: internal and external copper tubing and fittings
• Usage stage: surface preparation prior to soldering or brazing
• Intended users: professional plumbers and HVAC technicians

How to use

Apply the cleaner to the copper surface to be joined following standard safety precautions and ventilation. Use a clean cloth, brush or swab to work the product into the area, ensuring that oxidation and residues are dissolved and removed. After cleaning, wipe the surface with a dry, lint-free cloth and allow any remaining solvent to evaporate before applying flux and performing soldering or brazing. Follow local safety data sheet instructions and dispose of cleaning residues according to regulations.

Usage recommendations

For best results, test the cleaner on a small area first, use appropriate personal protective equipment, and ensure all surfaces are free from oils and loose debris prior to joining. Store the product in a cool, well-ventilated place away from heat sources and follow manufacturer safety guidance.
