Is black poly pipe the same as PEX?

“Black polyethylene” seems to commonly refer to HDPE pipe, which is pretty comparable to PEX. “Just” PE pipe is cheaper and less durable than HDPE – I’d advise against that underground.

What’s the difference between PEX pipe and poly pipe?

The main difference between the two is manufacturing. In PEX, the polymer chains are connected to each other and are called Cross linking, but it does not take place in PB pipes. Due to the cross-linked of chains, it results in revised material distinctiveness that is quite favorable for PEX.

Is PEX and polyethylene the same?

Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links. It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and insulation for high tension (high voltage) electrical cables.

What are the disadvantages of using PEX pipe?

PEX Plumbing Disadvantages

  • PEX may leach BPA and other toxic chemicals.
  • PEX is extremely sensitive to UV light.
  • PEX can be damaged by chemicals and pests.
  • PEX can’t be installed in high heat areas.
  • PEX is semi-permeable, which means liquid can enter the pipe.

Which is better PEX or polybutylene?

One advantage that PEX has over PB is its greater tolerance to high pressures. 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.

What is the life expectancy of PEX tubing?

30 to 50 years
Benefits of Copper Pipes While you can expect PEX to last for 30 to 50 years, copper piping will outdo it by about two decades, with a typical lifespan of 50 to 70 years. Copper is a more durable option that isn’t susceptible to rodents or sunlight. These pipes can easily handle water pressure of up to 1,000 psi.

Can you use PEX fittings on poly pipe?

PB has the same outside diameter as PEX of the same nominal size, but outside diameters differ slightly between the tubing types. This means that you should not use PEX fittings on polybutylene, but that you can use PEX crimping rings and PEX crimping tools on barbed PB connections.

Can I use PEX fittings on polybutylene pipe?
