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

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

Great working.

Its so easy using this product. Drill the proper size hole and insert it in and seat it right and presto, a leak proof seal for using barbed connectors.

The proper size for 1/2 inch schedule 40 pvc is the 3/4 inch size. The grommet is sized to outside of pipe diameter.

I purchased Hydrofarm HGGR50 Rubber Grommet for use with ½ inch PVC pipe. One of the comments said it could be used with a ½ inch PVC and 13/16 hole saw. There is no way they could be used as claimed. It put me in a hell of a bind. I had to improvise by using ½ inch CPNC pipe and a 7/8-inch hole saw. You need to remove the comments stating that it will work with ½ inch PVC. My satisfaction server will reflect my outrage.

Used these to construct drain line on a 3 gal RDWC bucket system. I was concerned at first that they might seep but there have been zero issues. Simple solution

Fit perfectly

The inside hole (id) is 1/2 diameter...it will not fit inside of a 1/2 hole (which would be OD of 1/2) Bamboozled again!

Great product and seller!

Received product promptly and as described.
