Hydrofarm HGGR50 (25 Pack), 1/2 Rubber Grommet, Black

quality made product.

Nice heavy duty grommets that will work great for my SIP project.

Great for your in home needs very well made

So just to clarify the 1/2 is outside diameter so I think that makes the inside diameter 3/8. I will still put them to use just frustrating when I needed inside diameter to be 1/2

working perfectly love it.

Happy with product

A +

Does not fit 1/2 pipe

Package the grommets were in was not sealed. Missing some

Great product, Great service, fast delivery, highly recommended.
