What are these Grey pieces.

[SudsnShine115]

We were fixing a leak above our self service bays yesterday, and when changing the fitting, we noticed the grey piece threads where the chemical lines come in was oversized.

Can someone tell me what these are where to get them and if there is a better option?

Thanks in advance!

looks like homemade foam generators. If you take them apart you will probably find it is packed with stainless Steel pot scrubbers.

They are pricey but they work great and last about 20 years

The home made ones work fine and cost maybe two bucks. Have one ens with threads so you can open and clean when needed.

That’s what they are “Foam generators” mine are hollow with a capped off ¼” nipple with a few 1/6” holes drilled into it so the foam brush solution is sprayed or agitated when it enters the foam brush generator chamber. I haven’t touched them in over 30 years

Or you could try just eliminating and putting in a "T" and see how that works.

Do you happen to have a picture you could share of this?

Nope, not after 30 years.
