Can’t stress enough how helpful and informative these videos are, please continue to upload thanks

[Gruntled]

Thank you for the video, my friend. I trust these, and to those who have seen them fail (come apart) - that happens when the pipes freeze, so the pipe would’ve burst anyway.

When I was in school, we had a project with PP, my instructor loved messing with me, pulled the O ring, was pissed that it held 225psi. The copper to copper is intended to be the seal. The o ring helps

[tazmaniandevil]

In shark bites the O-ring is the only seal.
In Propress the crip is the seal, the O-ring is a secondary seal.

[jamesd]

Many people seem to think these are inferior to soldering, and maybe they are. However O-rings used in hydraulic systems hold back thousands of psi of pressure and rarely fail on their own for years and years.

I believe you’re the best in teaching I’ve been working in Tiling over 25 years but never get involved in plumbing! Do you believe me now I start to take bathrooms refurbishment I do the plumbing my self 😅 and great soldering, but still waiting you to download so boiler fitting as I’m planning to start this September in college.
Thank you very much for all your Great videos and advantage channel

What about what happens when that rubber o-ring begins to disintegrate? Are they the same type of rubber in like a outside spigot that when it goes bad it gets mushy and gives off a black residual?

[jasparramirez]

I still prefer to sweat the connections but I use my pro oress when the water doesn't shut off all the way. It a great tool to have.

[AlbertLebel]

Excellent break down of how they work 👍

[Infoaqua]

I thought they say press fitting v brand . The o ring does not come in contact with water. It’s just a extra safety barrier

[Vincerama]

I'm guessing you can't use it on galvanized steel due to the fittings being copper, which would react with it?

[eragonthedragon]

Didnt know viega has this too. Usually just use em for water locks n such. Mapress is a similar system to this.

[maddog]

Hello my friend I'm here first today 😅

[markkirsten]

I've seen videos where the o ring is removed and they still didn't leak.

[john]

Out of all the videos on these fittings. You show them the best but i still dont trust them.

I took my comment from another video so i wouldnt have to retype it all.

"Heres the thing. A lot of old Fuds will say propress is trash just because.

Im a younger plumber whos been taught by all the old fuds. But ive got an actual reason i dont trust propress.

The rubber used in almost all press fittings for water lines is EPDM. its a really resilient rubber. It doesnt break down when exposed to water.

But Chlorine is a different story.

Heres a quote from a companies data sheet that makes EPDM rubber liners for storage tanks.

"Liner Resistance to Chlorine

All flexible liners will be attacked by chlorine but those produced from Fluorocarbon
rubbers, Fluor silicones and PTFE will a have “fair” resistance. However, these types
of products are not commercially available and are significantly more expensive than
Butyl or EPDM.

Butyl and EPDM are considered “non-resistant” and Butyl is rated as better than
EPDM as Butyl remains more flexible under chlorine attack and has extremely low
gas permeability (chlorine is a gas)

Mechanism of Chlorine Attack on Butyl and EPDM Liners

The chlorine attacks on the polymer by cutting the polymer chain and making the
material depolymerise. This oxidation takes place on the liner surface and the surface of Butyl becomes tacky and softer.
With EPDM the surface becomes much harder and more brittle."

This next part is relevent to how much chlorine is in tap water. Across the country there is between 0.2mg/L and 4.0 mg/L

"Chlorine Concentrations for Butyl and EPDM Liners

The recommended maximum concentration at ambient temperatures for Butyl and
EPDM liners is as follows:-

• Constant chlorine of max. 0.2 mg/l (ppm)
o Will not have a significant effect on the service life of the liner.

• Chlorine concentrations constantly higher than 0.2 mg/l
o Will have an effect on the life time of liners.
o The expected life time of the Butyl and EPDM liners is 20-25 years but
will obviously be reduced with higher chlorine concentrations and the
user must balance take this into account when calculating the
expected practical life of the liner.

• Temporary increases in concentrations
o up to 5.0mg/l for a maximum of 24 hours and not more than 20 times
over a year can be accepted without major effects on the liner
o Temporary increases of concentration up to 50 mg/l for a maximum
of 24 hours and not more then once a year, procedure according to
BS 6700, can be accepted without major effects on the liner.
o Or a concentration up to 500 mg/l for a maximum of 1 hour, followed
by an immediate clean water wash, can be accepted for disinfection."

And their liability info.

"Liability
Butyl and EPDM liners are by nature not resistant to chlorine, although decades
of practical experience in the use of tank liners proves that they have a prolonged
life when used for the storage of chlorinated water.
As the site and operating conditions and installation of each application are
beyond the control of the CSTVulcan, we are unable to assume any liability for
the effect of chlorine on the liners.
In respect of de-polymerisation of Butyl and EPDM liners due to chlorine attack,
there is no guarantee for the service life, express or implied, and CSTVulcan
shall under no circumstances be liable for any incidental or consequential
damages, direct or indirect, including but not limited to damages to equipment,
building, loss of production or profit of any other losses."

Depending on your chlorine level in your area. It can last for 25+years or start to fall apart after 5.

The chlorine steals electrons from the rubber and causes the exposed area to get hard. Hard rubber cracks. Cracked rubber leaks.

Ive seen 70 year old copper solder joints not leak. Ive yet to see a 70 year old piece of rubber that id trust a customers house to.

If you want to look up the pdf yourself google

"effect of chlorinated water on butyl and epdm liners - CST Industries" this should bring you to the pdf download.

I really wish i could just share the link.

Have a good one man."

Why is the pressure rating different for water vs air? Isn't pressure the same regardless?

[Gabey_inc]

How do you even cut these fittings open?

[nickcaluori]

LOOKS PRETTY SIMPLE FOR A GOOD JOB EASILY DONE ...THANK YOU G2L

[kurtbarrett]

I'm sure that O-ring is made of an excellent material, but no matter what it's made of it is guaranteed to fail at some point, much sooner than solder or threaded fittings.

[frankjames]

Until years later the rubber started to deteriorate
