Love these for lower pressure applications. Easier to put together than the 303 hose with 491 fittings!
Worked as expected. Very clean and easy way to build Vacuum lines for the Instruments. Clamps are history to me know!
Excellent fittings that drive pretty easily and grab the hose well. The description says the collar portion is internally threaded. The ones I received were internally ringed, instead of the coarse thread you might expect. They held very well despite this and I actually prefer it, though some have told me that the threaded ones have less problem with the hose backing out during assembly.
