yes they're much sturdier than the rectus fittings so they last ages.they are obviously a bit heavier but that doesn't matter and at this time of year with freezing temps. good for not leaking while you're working
I took a photo comparing them once, I'll see if I can find it later.
Why do you get through so many. I drill a golf ball and put it over the tail and hose.this lifts it off the floor and has the added benefit of being a bit easier to use when pushing the fittings together.
