Connecting Metal & Plastic Valves: 3/4 Ball Valve-gw-3-4, Reductive Joint, Flexible Conduit Tips

Hello,
let's assume I have a 3/4 ball water valve valve-gw-3-4-gw-3-4-ferro,main.jpg,
I attach to it some reductive joint of the type zlacze-proste-g-3-8-1-4-bsp.jpg. And now I would like to tighten some flexible plastic wire to this connector. It is known that the end of this pipe will be plastic. Like a link between a valve and a connector, it's paste, tow and hey. And those in the case of connecting a connector with a plastic tip? also pasta, also tow? Are there no such connections?

Thank you in advance for your response.

Ps. Could you advise some flexible plastic conduit? one with a diameter of 3 cm

Hi,

Such connections are sealed with a flat rubber gasket, such as a flushing hose.

It is worth that the connector on which you will screw the plastic element should be made of brass. They are more even and gaskets adhere better to them.

Look in the supermarkets in the garden section
They have both hoses and fittings for them.

I don't know how much flexibility you require from a plastic pipe, but look for polyethylene pipes (blue ones). They are available in diameters, probably from 16 and certainly from 20, take fittings for them with an external thread and screw into the valve normally on tow or Teflon, whatever you prefer. If such a tube is still too stiff for you, maybe think about a hose with reinforcement and use bands. You can also try welding polypropylene pipes, they fit polyethylene fittings, I think they are a little less rigid than polyethylene ones.

Dude, see what the nipple looks like inside and then you'll know if there's anything there at all.

I don't quite understand what you want to combine
Generally, the rule is as follows - at least in our company we apply it
you can normally connect steel with plastic, either PE (blue hose, white, twisted fittings) or PP-r welded plastic
If you have a delicate thread on plastic and you are not skilled in winding, take Teflon If you are doing quite well with winding, use tow Only for plastics, e.g. PE, do not wind on the first 2 turns, you can damage the thread if it catches crooked If the thread is too slippery or tow they rotate, deburr the thread
