Will these 1/4” top hat grommets work with 1/2 inch PVC pipe?

    I’m in the process of building a small NFT system. I went with 1/2 inch PVC for the plumbing and manifold because anything larger seemed overkill.

    I planned to use these grommets in the manifold for the feed lines but now I’m wondering if these top hat grommets will work without leaking. Looking at my 1/2 inch PVC pipe now it seems a bit small. I noticed these are mostly used with 3/4 inch PVC or larger.

    They should work fine, I’d do some test drills on scrap pvc. I have installed them on 3/4” flex hose
