Pex pipe expansion tool

You can use a manual PEX expansion tool or a cordless tool. We prefer the latter since it greatly simplifies the process and reduces time on the job.

Are PEX expansion fittings reliable?

Its resistance to freeze damage as well as corrosion, pitting and scaling makes PEX the most durable piping product on the market today. Its flexibility minimizes connections by up to half in certain applications, making it one of the fastest piping installation methods available.

Do I need expander for PEX?

PEX A uses an expansion-style fitting. These fittings are much larger in diameter the PEX B fittings, and require an expansion tool. Using the expansion tool, you enlarge the pipe and sleeve in order slide in the fitting.

Can all PEX tubing be expanded?

Flexibility - PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe.

Is it better to crimp or expand PEX?

PEX crimp equipment is a lot more affordable than the expansion kits. However, despite the pricing and form shortcomings, most plumbers prefer to work with expansion because installation is more efficient. There are fewer leaks, and it also seems to be more durable against extreme colds and frozen pipes, etc.

How long do you wait to pressurize PEX A?

For commercial pressure testing, condition the PEX-a to 1.5 times the test pressure then allow the pressure to drop to 10 psi before re-pressurizing to 1.5 times the test pressure. Repeat this pressurization/depressurization routine for 30 minutes.

Can you use crimp rings on expansion PEX?

Crimp fittings are compatible with all types of PEX tubing, except for PEX-AL-PEX. Crimp fittings are preferred for many applications since they are widely available and are the most affordable.

Why do PEX fittings fail?

Common Causes of PEX Pipe Failures PEX piping has a maximum bend radius, which can lead to stress on the pipe caused by improper installation. In addition, extreme bends and kinks place a very high local stress on the wall of the pipe, making it more susceptible to oxidative degradation.

Do PEX crimp rings leak?

As with any other pipes, PEX is not prone to leaking. Nearly all of the plumbing leaks occur at joints (connection spots) and most of them are due to incorrect installation. Much like installing PEX tubing, repairing it is also an easy process.

Do you need a special tool for PEX?

Connections for most PEX supply jobs require a special tool. There are several PEX supply connection methods, but only two affordable enough to be practical for DIYers: crimp rings and cinch clamps. Crimp rings are a band of metal, usually copper, that you slip over the fitting and compress with a crimp ring tool.

Why is my PEX a leaking?

PEX pipes are not actually prone to leaking. Accidental holes may occur, but most plumbing leaks happen at connection spots or joints which are caused by incorrect installation.

How do I expand my PEX pipe?

Slide your expansion ring over the pex tubing until it overhangs the end of your tubing by no more

Where is PEX not allowed?

You can't install PEX in high heat areas like near recessed lighting. This also means you can't connect PEX directly to a hot water heater, but you can use a connecting material to do this. PEX is semi-permeable, which means liquid can enter the pipe.

Can SharkBite PEX be expanded?

SharkBite PEX-A pipe and expansion fittings are an excellent system for plumbing jobs, offering many more advantages than rigid pipe. This system has superior flexibility, eliminates missed connections and is compatible with expansion, crimp and push-to-connect fittings. make a connection. and expansion rings.

How do you tell if PEX is A or B?

The second way is to identify the style of fittings. PEX-B will have metal rings — either cramp or clamp — whereas the PEX-A uses an expansion ring made out of PEX or a similar material.

How long do PEX fittings last?

PEX: Due to its flexibility and durability, PEX piping should last at least 50 years. PVC / CPVC: Under typical conditions, these pipes should last up to 100 years.

Are plastic or brass PEX fittings better?

Brass its typically the best choice when the application demands a stronger fitting. In addition, plastic PEX fittings have a thicker wall requirement under ASTM2159 Standard, resulting in a reduced ID which restricts flow, while brass PEX fittings are manufactured to ASTM F1807 allowing for a larger flow passage.

Does PEX last longer than copper?

Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
