QuQuyi 1/2 Inch PVC Bulkhead Water Tank Connector Adapter Fitting with Plugs Thru-Bulk Pipe Fitting for Rain Barrels, Aquariums, Ponds(Set of 3)

I installed one on a 18 gallon vinyl clothes bucket and I filled it with water and it did not leak.

Good quality bulkhead at a reasonable price and delivery was quick.

The outer threading is non std and meant only for the nut. Nothing else. Also weird it twists on in reverse counter clockwise but doesn't matter it is only for the locking nut.Material is very solid and dense.

I installed one each of these into three blue rain-water collection barrels. I could NOT stop the leaking. I suppose it was because of the flat size of the devices and the radius of the barrels. My remedy was to buy some "MECCANIXITY Silicone Rubber Gasket Industrial Flange O-Ring for 2.5 Inch Clamp White Pack of 5" ($10.39 for 5 rings) and put one between the outside nut and the barrels. This eliminated the leaks - so far. Seems like the seller (Feelers) would provide that extra confidence item. Don't particularly need nor want to have a plug with a nice O-ring!I have had no problems with the threads that others have encountered.I would buy more of these ONLY with the additional extra O-ring

Use these to tap my rain barrels. Allow good water flow for garden maintenance

Easy to install, build is of good quality, cost is very reasonable and seals very well

It's a heavy, HEAVY bulkhead, so I assume it is durable. But it has the most ODD threading: The OUTSIDE thread is Schedule 80 (NOT the conventional Schedule 40). The INSIDE thread is NPT (Normal Pipe Thread) -- no kidding: 3" O/D NPT.If it's used strictly as a drain-plug, it's a fantastic plumbing part -- BEWARE if you need to add plumbing extensions / diverters away from this bulkhead.Lastly, (I think this is a feature, and not a defect) -- the inside thread is "normal" threading in that clockwise rotation tightens: the outside thread tightens on counter-clockwise rotation.

I used the to replace leaking bulkheads on some rubbermaid stock tanks. They sealed very well and are very well made.The lock nut is a lefthanded thread so you have to turn it to the left to tighten it. It is smooth when tighteningthe lock nut. The o rings are of decent quality.The included plugs are also a welcoming addition.Fitment of the bulkheads are great.Make sure you measure you hole size before ordering the listed size is not the hole size. Hole size will need to be bigger.The only con that I have is I wish these came in black.I have been using these for almost 2 years on some of my aquariums also.Will buy more as needed.
