What is this?

[Joeg]

I have an Aquatic life 50gpd ro/di that works really well for my city water but this morning I noticed that the part in the photo was cracked and spraying a fine mist.

I can't seem to identify what this part is and what it does. It seems like a flow restrictor.

This piece is attached to the membrane waste outlet.

Can anyone shed some light on what it is and where I can find a replacement?

Thanks. That was the first place I looked but obviously overlooked it. Is this a part that needs replacing very often? Wondering if I should order 2.

Thank. I was surprised to see it cracked. I don't have the unit permanently set up and just attach it when I want to make a batch. Seems like that part failing could make a mess if not monitored.
