By angle adjustment, I think he meant that the pipes on each size can rotate
with respect to each other.

Hello:

Have done a fair amount of home plumbing type of work, but, surprisingly,
have never had need to use a "union".

Have to run a line from a washing machine water outlet to the machine,
and for various reasons, before I get to the hose itself, I could use a
Union in the rigid section to provide some angularity adjustment, as well
as the removable advantage they provide.

Have looked at them at HD, and frankly they make me very nervous.

What's your experience with these things.
e.g.,

Once you snug them up, do they tend to stay that way ?

Reason i'm asking is that there is no elasticity in the union coupling
itself, so it seems to me that if the threads back off, even a very small
amount, there will be leakage thru the ground and polished seat where the
two pieces actually come together.

Any thoughts on this ?
Safe to use ? Proven in practice pretty well ?

Are there any other types, or brands, besides the HD ones that are
perhaps of better quality ?

Thanks,
Bob

Union provides no more angular adjustment than a coupling. If you want
adjustability, use several back-to-back 45 or 22 degree ells.

Best regards,
