Does Viega work on PEX?

Does Viega work on PEX?

“Raxial” pressing technology Viega’s revolutionary Raxofix press connectors in combination with jaws are designed to axially slide the sleeve and radially compress it simultaneously. Just one step produces completely secure, homogenous pressing suitable for PEX and multilayer pipes.

What type of PEX is Viega PureFlow?

PEX-B, like Viega PureFlow, is created through the silane process, which is done after the HDPE is extruded into pipe.

Can you use crimp fittings on Viega PEX?

Viega PureFlow PEX Crimp fittings are compatible with the industry-standard black copper crimp ring. No O-rings are required.

Is Viega PureFlow PEX expandable?

The press technology of Viega PureFlow joins PEX in a secure and consistent manner. Not only does this route avoid the expansion of the PEX, but Viega’s Smart Connect technology makes it easy for installers to identify unpressed connections and avoid the potential for leaks.

Can you ProPress to PEX?

In addition, going from ProPress copper to PEX fittings, the PEX plumbing systems can bend around corners with each change of direction, instead of having to add a connection. This reduces materials and can also improve water flow for better performance.

Can you use Uponor pipe with Viega fittings?

They work with all Viega PEX tubing (including FostaPEX), as well as all other brands and types (A, B, C). Watts and Uponor press fittings are designed for use only with PEX-AL-PEX tubing (any brand).

Is Viega PureFlow PEX A or PEX B?

The Viega PEX system uses the PEX-b tubing (although you could also use another brands PEX-a) and a pressed ring securing the PEX to the fittings. Some advantages with the pressing system is that the fitting are now available with press rings already built-in.

Which is better crimp or clamp PEX?

Stainless steel clamp rings resist corrosion more effectively than copper crimp rings, which can be a major benefit in direct-burial applications. PEX clamps also tend to be easier to remove.

Is Viega Pureflow PEX A or PEX B?

How can you tell the difference between PEX A and PEX B?

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.

Can PEX pipe be used with Uponor fittings?

What type of PEX pipe is appropriate for use with hydronic heating and cooling systems? Uponor offers Wirsbo hePEX™ oxygen-barrier PEX pipe for hydronic heating and cooling systems.

Are PEX fittings brands interchangeable?

These systems are safe to interchange. The main issue with the crimp systems is the expensive tools you need to use them. You might be able to rent a tool, but I’ve never looked into that. Another option are the push-on “Sharkbite” type fittings that also work with A and B.

How do you tell if I have PEX A or PEX B?

Differences can be summarized as follows:

  1. 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.
  2. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.

Should you use PEX A or PEX B?

Bottom line, PEX A is more resistant to burst pressure than PEX B. PEX A’s expansive material can handle up to 500 PSI, which makes it reliable in extremely cold temperatures. Since PEX B is a more rigid material, it will not hold up as well in similar situations.

Should I use brass or plastic PEX fittings?

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.

Why are PEX crimp rings black?

The black coating is not a paint but a surface treatment which does not add to the dimensions of the ring. Brass Insert Fittings and rings are manufactured and certified to the requirements of ASTM F1807 to insure compatibility with all SDR9 PEX tubing and fitting components from numerous manufacturers.

Are PEX-A and PEX-B fittings interchangeable?

There are two parts to this transition: the PEX-A MIP adapter and the PEX-B FIP adapter. These parts will thread together and allow you to join PEX-A to PEX-B. The PEX-A side will require an expansion ring while the PEX-B side requires the crimp ring.

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 Viega PureFlow?

PureFlow lets you install remote manifolds giving each fixture in a home or building its own PEX tubing line. All Viega PureFlow fittings have Smart Connect® technology built in so you can easily identify unpressed connections. Both press and crimp fittings are backed by a 25-year limited warranty for added peace of mind.

Why PureFlow fittings?

Viega PureFlow fittings, manifolds and tubing are easy to install and engineered to help reduce water waste in potable water systems. PureFlow is the only system in the industry that offers press transition fittings – allowing you to easily transition from PEX to copper in traditional branch and tee installations.

What are the requirements for Viega PureFlow PEX tubing?

This material specification designates the requirements for Viega PureFlow PEX tubing. All Viega PureFlow PEX tubing is copper tube size dimension (CTS), SDR-9 wall thickness, and meets the requirements of ASTM F876 and F877. Materials

What is PureFlow PEX tubing made of?

All Viega PureFlow PEX tubing is copper tube size dimension (CTS), SDR-9 wall thickness, and meets the requirements of ASTM F876 and F877. Materials Viega PureFlow PEX tubing is manufactured from a cross- linkable, high-density polyethylene produced by grafting organo-silanes onto a polyethylene base.
