Water Fittings: Lubricate Valve Components, Spouts, Threads, Gaskets, O-rings & Prevent Limescale?

Question

Hello. I would like to ask honorable colleagues who are more flimsy about water fittings, whether it is possible (and possibly how) to lubricate components of water fittings when assembling, i.e.: valve components, movable / rotated spouts, threads, gaskets, orings, etc. Is this lubrication, at...

The grease won't help here, time does its job. Threaded connections greased before assembly are more easily dismantled.

Rubber parts - technical vaseline recommended.
Metal threaded parts - I personally give a little copper grease.

Which doesn't mean I'm doing right.
Except that in my Scottish village there is very soft water (flowing down from peat-covered mountains).

Lubricate, but what kind of grease?
Take into account contact with drinking water - petrochemical products will cause you to poison yourself.
In addition, EPDM rubber elements are used in the water fittings. It is a type of synthetic rubber that is resistant to hot water, but the presence of oils and greases causes swelling and dissolution.
Did you mean mechanical damage due to cavitation under the word "eating"?

You can lubricate, and actually you should lubricate moving parts inside the valves and gate valves. Lubrication increases their service life, and is required in many cases. It is obligatory to grease the threads of the mushroom valves, all O-rings, and after a few years of use, the connection of the ceramic insert with the knob in single-lever faucets. I don't even mention the valves of all types of sizes, because their lubrication is something obvious for everyone.
It does not make sense to lubricate the outside of the fitting.
Appropriate lubricants should be used for lubrication, and there are many of them. If you are not sure about the offer or leaflet regarding the contact of the grease, e.g. with drinking water and at what temperatures, request PZH approval.
I know what lubricant they use at the plant of the largest Polish manufacturer of fittings, but I will not write so as not to be accused of advertising.
Here is an example of such a grease: link

The knobs do not look like brass castings. Rather, ZnAl or aluminum alloy, materials susceptible to corrosion. I think this something is a Chinese production bearing a Polish brand.

You're right, brass doesn't crumble that way.

Knobs like nothing. he knew the heads in the taps as if they were brass.

these chanterelles are well eaten At Allegro you can buy new steel - brass, chrome, for approx. PLN 10 / item, using the password: retro dial. greetings

My main point is whether it can be secured somehow so that the eating of these taps does not continue: It is known that I do it in the car in some cases, but I have concerns in the fittings, especially after the entry: So threads and gaskets / O-rings are better not to lubricate ?! Can I grease spouts of taps and valves? Can I lubricate the axis / valve stem contact area at the contact point with the valve sleeve? I would add that it was not a big problem to spin everything up. The problem was the disassembly of the taps (they are pressed in by means of plastic elements), which were dismantled only after the chemical dissolution of the taps' corrosion. Greetings.

The fact is that the taps are actually made of some kind of aluminum alloy, because they oxidize to a similar degree to this metal, except that they are much heavier than aluminum, i.e. ZnAl.
I cleaned, smeared, folded and works - not leaking. I left the original O-rings because they were completely unused, did not crumble and were more flexible and tight than new ones. The main problem of the battery was: stone, corrosion and small pebbles, which I found inside the valves. The taps will not change, because I have found that in case of further problems, both batteries will be changed. These are about 15 years old, so they have already earned a living. :-)

I would like to thank everyone who participated in the thread for their support :spoko:

and I wish you all the best in the new year!

I close the topic.

Greetings.
