Cross-linked polyethylene (PEX) tubing is a plastic material used for water supply piping systems. The product offers several advantages over copper, PVC, and galvanized steel plumbing pipes. PEX is flexible and easier to install than a rigid pipe, and it offers high heat-resistance and long-term durability.

PROS. Installing PEX does not require soldering as does copper and galvanized steel. PEX expands, making it more resistant to freeze-cracking than either copper or steel. PEX does not corrode, which can happen with both copper and steel pipes, leading to leaks and contamination of the water supply.

Replacing all of the plumbing in a 1,500 square foot, two-bathroom home with copper piping costs between $8,000 and $10,000. But using PEX would cost just $4,000 to $6,000, according to Gove. That's because of lower material and labor costs.

Re: Kitec Vs Pex IPEX offers both standard PEX tubing, and their composite, which is what you are referring too. Just to clear things up. IPEX is the manufacturer, not the product.

Asbestos-cement, CPVC, PE, PVC, or PEX water pipe manufactured to recognized standards may be used for cold water distribution systems outside a building. CPVC, PEX water pipe, tubing, and fittings, manufactured to recognized standards may be used for hot and cold water distribution systems within a building.

Around here, Pex is used for underground gas piping of both natural gas and propane. It's yellow polyethylene similar to plumbing pex but not as thick walled usually.

SharkBite non oxygen barrier pipe is manufacture as PEX-B and SharkBite oxygen barrier pipe is manufactured as PEX-C. As background, the methods for cross-linking are: ... PEX-B: Silane This method involves grafting a reactive silane molecule to the backbone of the polyethylene.

PEX is the plastic piping that came about to replace the polybutylene. As a general rule you can assume that it is PEX if it any color but gray if it was installed after 1998 and polybutylene if it was installed before 1993.

Red PEX pipe carries hot water. Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. Gray PEX pipe, like white, can be used for either hot or cold water (although not all DIY centers carry gray).

The traditional way of connecting PEX to copper involves using a threaded sweat adapter on the copper side (to connect with the PEX fitting) and soldering to create a watertight seal.

The main difference between PB and PEX is in how the material is created. ... Different manufacturers may have different numbers, but PEX will always have greater pressure limits than PB. So if you will be pumping water, or the pipes will be exposed to the cold, PEX is a better option than PB.

Q: Can I use PEX pipe for compressed air applications? A: No, PEX pipe is not intended for compressed air applications. I had pex in my last shop for six or seven years.

Polyethylene (PE) and polyvinyl chloride (PVC) are the plastic pipes most often used for underground utility construction. ... PE is more flexible than PVC. A primary difference is the way lengths of pipe are joined together and to other pipe materials. Compressed air or gases ought to not be introduced in to PVC pipes.

A: No, PEX pipe is not intended for compressed air applications. I had pex in my last shop for six or seven years. It worked fine. Super easy to modify.

PEX is designed for liquids and shouldn't be used for air lines. The tubing is "likely" ok, but the fittings are not, AFAIK. There is a similar product out there, however, that is designed for air. A lot of people do a lot of things that they probably shouldn't...

Cross-linked polyethylene (PEX) has been used since the 1980's for radiant heating systems, and has become popular for potable water in recent years. ... High-Density Polyethylene (HDPE) pipe has been used for decades in non-potable water applications. In particular, HDPE pipes are often preferred for their welded joints.
