Very handy, but I never trust them and only use them to stop debris getting in to pipe ends or as a temporary secondary stopend (like after a valve), or temporary plugging a vent pipe or to give me time while I work with pipes with water in them. They fail so easily and can be knocked off too easily. A smear of silicone grease on their O ring keeps them easy to slip onto pipes.
I was removing a shower pump yesterday, and one of the not dissimilar to Speedfit joint pump hoses started leaking when I touched it despite me having the water off.

If they go stiff silicon spray helps a lot

You beat me to that! I find older, dry and slightly tarnished pipes are difficult getting the push fit onto & especially off, without some silicone grease on the fitting.
But whatever happens some of the Speedfit after you use them loads of times,- they just stop gripping the pipe.
I prefer brass stopends and just replace the olive for anything risky. I have 2 brass stopends on an unoccupied flat at moment to keep basin pipes safe if someone turns stopcock on to flat.

I've got a set on a job capping the shower feeds off as a temporary untill the new shower was fitted, that was 14 months ago, customers got 3 other showers and doesn't want to spend the money, I'm still fearing the day her number rings me

A bit of spit on little finger to lube it up if its an old speedfit cap. I will throw it away if it looks old though

A lot of push fit fittings are already lubricated with silicone grease, although it isn't always visible. Some copper push fit have a ridiculously big amount of grease inside them when new.
I like to lube the tapered tip of my pipe with a slight smear of grease before I attempt to push it in. And I know how that sounds. :smile:

Did a job for the neighbour of a work colleague 13(I think) years ago when I was in college doing my first plumbing course.
It was to remove a downstairs cloakroom, the hot and cold were fed down from the ceiling cavity and I cut them and put 2 John Guest speedfit stop ends on, then proceeded to remove the basin and W.C.
Got a mate to mortar a couple of bricks in the hole were the soil was and put a 4'' cap in the soil spigot after removing the old soil from the loo. I was pleased as punch with the job.
Fast forward to last summer - got a call to install a cloakroom, went round and recognised the house, I knew I'd worked there before but wasn't sure when or what it was I did there, the lady of the house didn't recognise me either.
Anyway she explains that there used to be a cloakroom and she wants one putting back, has a look and remembered the job, looked up and those 15mm JG stop ends were still there holding fine.
In the process of doing the job I found the McDonald's wrapper in the cavity where my mate had bricked up the hole, he's rough as sandpaper that lad 😉 /irony

TLDR: I know they 'can' last 13 years without problems 🙂
