Questions about this item

What tube and pipe sizes does the 3175 12 21 connector accept?

The fitting joins a 12 mm push-to-connect tube on one side to a 1/2 in MBSPT pipe thread on the other.

How do I install the fitting without damaging the pre-applied sealant?

Push the 12 mm tube firmly into the collet until it seats, then thread the 1/2 in MBSPT end by hand before final tightening with a wrench.

When should I replace the nickel-plated brass connector in a vacuum line?

Replace if the brass body shows corrosion, the collet no longer grips the 12 mm tube, or the pre-applied thread sealant has dried out and leaks at 290 psi.
