It would be nice if whoever manufactured these items could work to better tolerances on the threads, but I don't suppose they will, and the item works does what its supposed to, even though its a bit "sloppy", but no worse than others.

It workers well although the thread was not the best

Good price. This is threaded the whole way through - I actually cut this down to about 8mm to create a smaller gap between two metal clad sockets

Good

Selected based on the outside diameter mated with (male thread) brass bush as means to adapt an engine exhaust outlet (petrol powered AC generator) enabling connection of 24mm ID stainless steel tube.

Don't bother with this rubbish!

Absolute garbage! Thread so poorly formed that in some examples, a male brass bush can almost be pushed into the coupler without rotating! Most will not tighten due to slippage!

I've wasted hours this week, not to mention fuel by having to return to site to replace these unbranded items with branded types from another supplier!

works fine and seem reasonable quality

Used for a different purpose but fit exactly our needs as a gate bolt receiver

Was exactly what we needed for the receiver for a gate bolt to prevent future damage to the render

Does the job.

I used this coupler to link 2 back boxes together along with two male Brass Bushs. It spaces the back boxes and holds them firmly while allowing the cable to pass between them.
