What is ASTM F1807?
ASTM F1807, Metal Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross‐linked Polyethylene (PEX) Tub.
What is PEX F1807?
F1807 – uses PEX insert fittings that are crimped in place, using a copper crimp ring, a stainless ring with ears (Oetiker) or a stainless sleeve. Also, the fittings are available in both lead free brass and poly (PPSU). This method can be used on all PEX tubing types (A, B or C)
What is ASTM PEX?
ASTM standards for PEX. ASTM F2023 Standard Test Method for Evaluating the Oxidative Resistance of Cross-linked Polyethylene (PEX) Tubing and Systems to Hot Chlorinated Water.
Are all PEX fittings interchangeable?
When installing PEX pipe and fittings, it is important to stick with the same manufacturer for all components. Mixing different pipe and fittings from different manufacturers can limit the warranty and add confusion/frustration if there is a need for service.
What is PEX A and 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.
Can Zurn PEX be expanded?
Considering that our PEX can be bent as tightly as any PEX on the market and it is expandable, we believe we have achieved the optimal balance.
What is the difference between PEX and Uponor?
Uponor manufactures PEX-a tubing is considered the superior type of PEX in the industry because the crosslinking is done during the manufacturing process when polyethylene is in its amorphic state (above the crystalline melting point).
Is HDPE the same as PEX?
Almost all PEX used for pipe and tubing is made from high-density polyethylene (HDPE). PEX contains cross-linked bonds in the polymer structure, changing the thermoplastic to a thermoset. Cross-linking is accomplished during or after the extrusion of the tubing.
How do you tell if you have PEX A or PEX B?
Differences can be summarized as follows:
- 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.
- Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.
Is Zurn a PEX B?
Zurn Pex, Inc. chooses the Silane (PEX-b) method to manufacture its tubing. While high degrees of cross-linking can be achieved using this method, it is unnecessary because the density of the base resin for Zurn PEX is higher compared to PEX-a and PEX-c methods.
Which is better Uponor or PEX?
There are three different types of PEX tubing: PEX-a, PEX-b, and PEX-c. Uponor manufactures PEX-a tubing is considered the superior type of PEX in the industry because the crosslinking is done during the manufacturing process when polyethylene is in its amorphic state (above the crystalline melting point).
Are wirsbo and Uponor the same thing?
Uponor (formerly Wirsbo) has been making PEX pipe for radiant floor heating since 1970, longer than any other PEX manufacturer.
Is Uponor and ProPEX the same?
PEX pipe is made by a handful of companies, but the best version I’ve discovered so far is part of a system called ProPEX. It’s a proprietary brand of PEX connections and pipe invented by an international company named Uponor (uponor.ca) and based in Finland.
