Product review (5 stars): Excellent quality, flow seems to work, would recommend.
Change your hoses. Change your hoses. Change your hoses.

That said, these are very high quality hoses - they are very tough, screw on well, and should do the job of STOPPING if there's a leak. I didn't test it, for obvious reasons. they maintained good flow in use, were easy to install, and won't strip.

I would recommend.
