How to Install PEX Tube
PEX tube is a plumber’s best friend. Not only has it taken away some of the problems associated with copper pipes, it has drastically reduce leaks and above all it improves plumbing performance. PEX tube is flexible and it’s resistant to both thermal and chemical attacks. PEX tube is a time saver because it eliminates the time it takes for a connection bonded with glue to dry. In fact, PEX tube comes in handy in a whole lot of domestic and industrial applications. Let’s look at how to install this plastic pipe in cold and hot water systems.
- PEX Tube
- PEX Plastic Tube Cutter
- Crimp Rings
- Crimp Tool
- Go/No-Go Gauge
Step.1 – With a tape rule, measure out the PEX tube length for the job.
Step.2 – Use the PEX plastic tube cutter to make a neat, and square cut. This step is very important.
Step.3 – Next, slide the appropriate size of crimp ring over the PEX tube. Push the ring until it has gone passed 4 inches from the end of the PEX tube.
Step.4 – Push the PEX tube onto the fitting until it swallows the entire shoulder of the fitting. Use the crimp ring to hold the PEX tube and the fitting tightly in place.
Step.5 – Carefully position the crimp tool on the crimp ring and squeeze as required. The crimp tool must be exactly 90 degrees to the work-piece while holding the crimp ring before squeezing. Verify to see if the connection is properly done.
Step.6 – To be absolutely sure of what you’ve done, use the corresponding slot of the Go/No-Go gauge which must be of the same size as the crimp ring to conduct a second test. The Go/No-Go gauge slot should slide easily across the compressed crimp ring.
In order to avoid a weak connection, the PEX tube must properly cover all the ribs on shoulder of the fitting. Finally, always ensure that the crimp tool is perpendicular to the crimp ring before compression.
