Are brass PEX fittings better than plastic?

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.

Is brass better than plastic?

Higher Pressure Rating — Brass has a higher tensile strength and more elasticity than plastic which make it more resistant to bursting. Higher Chemical Resistance — Brass is more resistant to chemicals typically found in irrigation water and therefore less susceptible to failure due to cracking.

Which type of PEX fitting is best?

PEX-A, which has the most flexible tubing and best freeze- and kink resistance, is ideal for use with kitchen and bath fixtures. PEX-B is slightly less flexible and less freeze-resistant.

Is it OK to use plastic PEX fittings?

Plastic PEX fittings are OK

And pros don't want a callback to fix their own work on their dime. So obviously, pros trust the plastic fittings. Manufacturers trust them as well; the warranties for plastic fittings are similar if not identical to those for their metal counterparts.

Can you use brass fittings on PEX?

Advantages of Brass fittings

It has some good strength and can be very reliable for PEX fittings.

Brass or Plastic Pex Fittings? How About Stainless Steel!

Are brass hose fittings better than plastic?

The brass outer compression ring also allows more 'bite' into the hose than their plastic equivalent. The inner core of the hose connector is manufactured from limescale resistant material to reduce problems in hard water areas. The brass tap fitting is also much, much stronger than plastic 'snap-on' fittings.

How long do PEX fittings last?

Generally, PEX pipes last for 25 to 40 years before they need to be replaced. By comparison, copper pipes last for around 50 to 70 years. PVC pipes also last 50 to 80 years. CPVC pipes last 50 to 75 years.

Why do PEX fittings corrode?

When water flows through your PEX pipes, the zinc in the fittings can seep out of the fittings, causing a white residue to build up inside the pipe, constricting water flow. It works the same way as plaque that constricts blood flow in your arteries.

Can I use brass fittings for water?

The standard lead-free brass fittings are made with marine-grade DZR brass and are currently acceptable under the Safe Drinking Water Act, but will be restricted to non-potable water applications as of 2014.

Why are my PEX connections leaking?

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.

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.

What is the difference in PEX fittings?

Again, the main distinction lies in the manufacturing method, which is what assigns an A, B or C to PEX. 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.

Is PEX OK for drinking water?

These leakage products consist of residues of additives used during production to give plastic pipes their desired properties, as well as any subsequent breakdown products. The study showed: There are no health risks associated with drinking water from PEX pipes.

Are PEX fittings copper or brass?

There is uncertainty about the use of plastic and brass materials, stainless PEX crimp fittings incorporate all the positive features of plastic and brass, with none of the negatives. They provide high strength, high corrosion resistance and large flow passages.

Do PEX fittings reduce 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.

Can you use crimp rings on plastic PEX fittings?

You may use pinch rings, copper crimp rings, pro crimp rings, and stainless steel sleeves with any of our Poly Alloy fittings. So at least as far as their products go, there should be no problem.

What are the disadvantages of brass?

DISADVANTAGES OF BRASS

Brass requires a good deal of maintenance since it is prone to a blackish tarnish. The biggest challenge to upkeep most metals, including brass, is the removal and inhibition of tarnish. All substances, especially metals, oxidize when exposed to the air.

How long do brass fittings last?

Brass: An allow of copper and zinc, brass piping is slightly less common than copper piping but has a slightly longer lifespan. Generally, brass pipes can survive between 80-100 years.

Does brass leach into water?

Water sitting for several hours or overnight in a brass faucet can leach lead from the brass faucet interior which may produce high lead levels in the first draw of drinking water.

Do mice eat PEX tubing?

The Problem

Mice and rats will chew through anything they can, including plastic, so PEX tubing is at just as much risk as the plastic-coated wiring in a car or an HVAC unit. While all rodent damage can be expensive, if rodents chew through a home's PEX water pipes, the result can be disastrous.

Why do brass fittings turn green?

Why do brass, bronze and copper turn green? All of these metals contain copper. When copper reacts with oxygen, it oxidizes and generates a greenish-blue layer that protects the metal from further corrosion. Any metal that contains a high amount of copper can turn green.

Where should you not use PEX?

PEX can't be installed in high heat areas.

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.

Will PEX last 100 years?

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.

Is there a difference between red and blue PEX?

PEX Particulars

Although there are three types of PEX (see Label Lingo, below), the different colors don't connote the distinctions; they simply make it easy for the installer to identify which lines carry hot water and which carry cold. Red PEX pipe carries hot water. Blue PEX pipe carries cold water.

Does PEX last longer than copper?

Although copper piping takes significantly longer to install, it does provide a longer overall lifespan. Copper manufacturers typically offer a 50 year warranty in comparison to 25 years for PEX, but this of course may vary by supplier.
