Nice product
I have a multi axis grinder that has several hundred feet of pneumatic poly lines as part of its operating system. Lines are under pressure in excess of 85 psi and are generally under 5mm in diameter so they’re always breaking and shutting down. These connectors slip right on and seal up nicely.
