Amazon Customer: Great grommets but 1-1/8" hole saw IS WAY TOO BIG!! 1" is the key.

Capt. G.: Specifically, I use these Hydrofarm Rubber Grommets, outside, in (22) Alaska Grow Buckets. They're all in their 3rd season with no leaking. (Not bad in this Texas heat.)
Drill the hole size in your recepticle, per instructions. A bit of vaseline on the grommets makes it easier to seat them.
I can't recall the size of pipe these grommets cater to. But, when it becomes time to place the pipe into the grommet, do yourself a favor, (if you have a shop grinder; great), grind off some of the pipe so that the pipe is reduced in diameter, at a taper for about 3/4 of an inch from the end of the pipe. You will now find it possible to insert the pipe through the grommet. (Use the vaseline again.)
Good fortune to you.

Chippe: These things are amazing. Drill the right size hole and insert the grommet, then, insert the pipe. Be sure that the grommet is fully seated, I used this size for my 1/2 " PVC pipe. No leaks. Use a 1 1/8 " hole saw (not a spade bit). The drill size was discovered be the greats before me. I stand on their shoulders.

AIS: I used these with 3/4 inch barbed fitting like the recommended comments, been using them in a hydro system project I've been working on for about a month now and works like a charm. Had a hard time finding something that works well, leak-proof, and doesn't cost 10x the price. Great Product. Will buy again for my next project ! Thank You Hydrofarm.

RSM: These are great rubber grommets if you are running any sort of dutch bucket bato buckets or dwc systems. I purchased these to build a diy system that I saw on a website using 10 gallon plastic totes on my deck. I used about 18 of these to build an eight tote system that housed 16 pepper plants. They are all doing great and producing well. The rubber is very high quality. They were not cheap and quote expensive when compared to the others. As a gardener who has used many of these before I can say with confidence that these are quite possibly the best so far. No leaks whatsoever. I used both PVC and even regular rainbird drip irrigation 1/2 inch supply lines and the rubber grips them well without a single leak. The hole needs to be exactly one inch so use a clean drill bit and file down any rough spots. The grommet holds on and slides in easier with a little oil. I used a touch of coconut oil to ease them in, in many buckets I didnt even need any. Its held up really well so far for about four weeks now in the hot sun without any signs of damage. I used the remaining ones on 5 gallon food grade buckets where it worked perfectly. The grommet is well worth the price.
