Connects to Copper without having to solder

The most common residential plumbing materials for water-supply lines are copper pipes. Copper piping is very popular because of it durability and it’s variety of grades. It is used extensively to convey potable water because of it’s corrosion resistance, machinability, and high level of heat transfer.

connects to pex in seconds
Quickly Connects to PEX without Special Tools

Cross-linked polyethylene, or PEX, is a bendable plastic piping toughened by a special chemical process that strengthens the polyethylene. Because of its ability to withstand a wide range of temperatures (subfreezing to 180 degrees F), it is quickly gaining popularity as a supply pipe for residential plumbing.

connects to cpvc in seconds
Easily Connects to CPVC Without Messy Glues

Chlorinated polyvinyl chloride (CPVC) piping is commonly used for hot and cold water applications. Ideally suited for applications where temperatures can reach up to 200 °F (90 °C). The ability to bend and shape CPVC enables its use in a wide variety of applications. It exhibits fire-retardant properties and chemical resistance.

Common Copper Pipe Applications
  • Oil-free compressed air
  • Vacuum systems
  • Heating and cooling
  • Chilled water
  • Hot water
  • Car wash applications
  • Sprinkler systems
  • Potable water
  • Fluid transfer
  • Underground fluid piping

Joining Tubing

Q: Do I need to prep the ends differently than a solder joint?

A: No, as with sweat copper fittings, the tube must be chamfered, de-burred and reamed (free from
burrs and debris). Quick Fitting Holding Company, LLC. recommends the use of an Inner/Outer Reamer to chamfer, de-burr and
ream tube ends. These steps are essential to ensure the proper connection of your COPRO Pure® Lead-Free push-to-connect
fitting. Also, be sure to draw an insertion mark on the tube to indicate proper insertion of the
tubing into the fitting.

A: A stiffener is only required when connecting COPRO to PEX tubing,

Installing, Testing and Flushing Your COPRO® System

Q: Can a COPRO Pure® Lead-Free fitting blow off a water system?

A: NO, the grip ring technology utilizes an opposing force principle, which simply put, the higher the
force used to pull the fitting, the deeper the fitting bites into the tubing.
