Fitting itself is fine, does the job. Took longer to ship than I expected and I had to reschedule the repair around it, which was a pain. No complaints about the part though.
fit perfect
Dropped right in, no leaks, no fuss. Been running it on the loader for a couple months now and it's holding up fine under daily use.
works great
Ordered two of these to finish up a cylinder repair job. Fit the hose perfect and the O-ring seated clean the first time — didn't have to mess with it at all.
