Pipe coupler issue - connecting two male fittings

[SimonG]

For the hard of reading.

You would not connect a flexi conn onto a fitting designed for an olive. It will cut the rubber washer and leak.

Bad advice to suggest otherwise.

Well, what is the purpose of a female union if it isn't to connect to a male thread (please don't say to connect to a female thread with pipe offcut!)? I would never recommend connecting two males together with a very short or practically nonexistent offcut as when the unions are tightened, there isn't enough strength in the offcut to withstand the tightening and therefore a leak occurs.

They are designed for a male connector with a flat edge. Not a raised edge.

I was trying to be nice mate. But your point sounds much better😛😛😛

Ah right, I see. I didn't realise there were 2 types of edges - thought they were all with raised edges. I can totally understand that then. Thanks for pointing that out. By the way I'm not a plumber, just a DIYer plumber 😀

The strength is the copper pipe inside both female unions.

Well thing is, I've attempted to bridge two fittings together with a small offcut 15mm copper where the two fittings were practically touching each other, but when I tightened everything, it did actually weep so had to replace the offcut with a longer one. Yet, I've seen a plumber by trade do exactly the same thing and he tightened it so hard the fittings actually squeaked, yet his didn't leak!

 

[ShaunCorbs]

the squeak is how you know there correctly tighten

i normally use wras approved jointing compound which helps stop the fitting squeak

you will soon find how much to tighten compression fittings just takes some practice

Well, rather than using an offcut to connect two fittings closely together, lets say for instance a PRV and an inlet strainer upstream of it, would a female to female equal bush still be sufficient?

Definitely true what they say you learn something new everyday (awesome to learn about those two male edges)

Is this in your home?

I would use a female threaded prv and line strainer

In a holiday home abroad where the water pressure is so high that it's ruining kitchen fittings etc. I've already bought my PRV and inlet strainer, but the thing is, due to cold winters, piping is all done in PPR so I want to avoid the use of copper. Sorry this thread has deviated slightly.

Thanks but hmm it's tricky for me to understand and visualise. Perhaps a link would help. But would my fittings be adequate?
