Not sure what else you could call it, I have (approx) 4mm pipe feeding a boost gauge on another project and the needle was bouncing and rattling quite annoyingly, overlooked the T piece that came with it but the take off on the t piece was minuscule compared to the 2 sides that it would tap into. Anyways, plumbed that in and quietened the gauge down and stopped the bouncing. I beleive Frosty and Mikey had the same issues but bought some filter/reducer things.
My XUD has tiny nylon pipe feeding the gauge so that doesn't rattle at all.
As for your EMP gauge mine did the same, ended up fitting a glycerine one.
