Pex expander tool

Installation of PEX A piping requires an expansion tool. The fitting is larger in diameter, so you'll need to enlarge the pipe and sleeve with the tool, then slide the fitting in. Once you remove the tool, the material will shrink back to normal size, tightening it around the fitting.

What is a PEX expander tool used for?

Using the expansion tool, you enlarge the pipe and sleeve in order slide in the fitting. Because PEX A is expandable, the material's memory will ensure that it will shrink back to its normal size, tightening snugly around the fitting.

Is PEX expansion or crimp better?

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.

Can you expand PEX with heat?

Warmer temps mean the PEX will take back its original shape more quickly. On the flip side, the colder it is, the fewer expansions you want to allow as too many expansions will require you to hold the PEX on your fitting for an extended period of time.

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.

What is the best way to connect PEX tubing?

The most common connection method used in PEX installation is the “Crimp” method. This process involves sliding a ribbed fitting into the PEX tube and crimping a seal ring around the connection point. These rings are typically made of copper, but may be found in plastic as well as brass.

Do PEX fittings reduce water flow?

At a rate of 8 feet per second, the CPVC fitting will cause less than 1% restriction in flow while PEX fittings create a 23% to 54% reduction in flow, depending on the fitting used.

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 reliable are PEX expansion fittings?

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.

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.

Which is better PEX A or PEX B?

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. Kink-Resistance - PEX-A has the greatest resistance, PEX-B the lowest.

Do professional plumbers use PEX?

Most plumbers prefer to work with pex pipes for this reason. These pipes come in a variety of sizes, from ¼-inch to 4-inch. The flexible pipes are constructed from polyethylene that is cross-linked to make it flexible.

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.

Does SharkBite work on PEX A?

Identify the pipe material. SharkBite brass push-to-connect fittings are compatible with PEX, copper, CPVC and HDPE pipe. They come with a PEX stiffener pre-loaded into the fitting for PEX and HDPE, and the stiffener doesn't need to be removed for copper or CPVC applications.

How many PSI is PEX good for?

PEX tubing is SDR9 with standard hydrostatic pressure ratings of 160 psi at 73°F (1105 kPa at 23°C) and 100 psi at 180°F (690 kPa at 82°C).

What pressure do you test PEX at?

A 30–40 psi pressure test should remain during phases of construction to monitor system integrity. NOTE: If tubing is to be left under pressure for a longer period, make sure to reduce the pressure to 30 psi.

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.

What's the difference between PEX AB and C?

PEX A is made using the Peroxide, or Engel, method. PEX B is formed using Silane, or Moisture Cure, method. This is the most common PEX pipe type out there. PEX C is created using the Electronic Irradiation, or Cold, method of cross-linking.

Can you bend PEX with heat?

Warm the PEX Tube Though PEX tubing bends well, it can crimp if it is bent improperly. Start by warming up the PEX tubing, either by letting it sit in a warm room or by using a heat gun at the lowest temperature setting.
