RAINPAL BBF020 LF Compliant Brass Bulkhead Tank Fitting (Double Female 1/2” NPT and Male 3/4" NH Garden Hose Threaded, 4 oz each) (2)

Far, FAR sturdier than the little plastic nub they replaced, this little pass-through will probably outlast the barrels I installed them in. Getting them into the barrels was a little fiddly (Yes, I got my dumb 6’ tall, broad shouldered butt stuck in a rain barrel and couldn’t get out for five minutes. No, there’s no video of that, thank goodness. I think I got away with no one noticing.) but once I got them in they’re exactly what the doctor ordered. Two installation notes: - they are bigger than the standard pre-drilled hole in the rain barrel. I had to widen it. - if you need to adjust the alignment of the tank fitting after you’ve tightened it down, you may need to loosen it first to preserve the washer. I connected a y-splitter to the outside, and needed to rotate it in order to get the orientation I wanted; twisting it without loosening it first deformed the washer and broke the seal. It worked fine after reinstalling.

While the description said this was for a rain barrel, it was also the perfect fit for my needs. I have a dehumidifier that is set up for continuous use with a drain hose. Luckily for me, the place where I wanted to put it had a sink previously. We used the old sink drain to feed the hose into, but I wanted something a bit more permanent. I used an ABS cap and drilled a hole through it to insert this fitting. I attached the fitting to the cap, and glues the cap on the drain. Now we have an airtight leak proof connection that cant be accidentally pulled out of the drain.

This is an extra good product. I chose the metal version of this product because the interior diameter is larger than that of its plastic versions out there. The actual outside diameter of the nipple was 1-1/32". Because I wanted a near snug fit, I drilled a 1" hole with a paddle bit, and then filed the rest until I could slide the nipple in without any resistance. I only had to file 1/64" of the material all around the hole (1-1/32" nipple - 1" hole) / 2 = 1/64 material to file all around hole. Only took me a minute or two with a good small metal file (not to be confused with jewler's file). The rubber "O" ring gasket sets so close to the out side diameter of the nipple, that I did not want to risk having the gasket riding the edge of the hole. I like my gaskets setting on a flat surface, for maximum sealing area. The directions say you can drill a 1-1/16" to 1-1/8" hole, but I wouldn't go any larger than a 1-1/16" hole.

Works like a charm, well built, no fuss. I *strongly* suggest that you buy this one: go brass, pay the extra few cents and don't buy the cheap plastic ones. Your wisdom will be rewarded! Note: This is not a lead free product, it's OK for irrigation but it should not be used for drinking water. The inside (ID) is bigger than it looks on the picture, and it's a good thing. There is more flow ;-) I have 3 barrels in line and I was a bit worried about the flow between them when there is a downpour. The OD of the tread is 26.3 mm / 1.03" , so you can use a 1" spade and finish with a file. Recommended is 1 1/8" The only thing I did differently was instead of dropping the the bulkhead into the barrel and then go trying fishing it, I used a bit of irrigation polytubing : It allows to make the whole process faster. The ID of the bulkhead fits perfectly, and you just bring the bulkhead directly to the hole. see picture.

I used these for repurposed 55-gallon HDPE (Type 2) Blue Barrels for rain collection. They work GREAT! Make sure to but the holes exactely sized (tighter fit the better) and smooth out the holes to remove any burrs from the process. I used a nylon chord to guide the bulkhead into position. Since the bulkheads are also threaded on the inside, it was easy to grab and pull through. Put on some Silicon around the threads where the nut will tighten up, let dry and use. Worked so well I had to order more. Avoid the plastic bulkheads if you can. These are priced such that it a no-brainer to go with them. Shipping was on-time.

I had a similar unit fail, and lost all the water in my rain barrels. I replaced it with this, and so far, so good. Install is easy, and it appears to be performing well, without leaking. Time will tell how well holds up. Good that it claims to be lead free.

I have been using rain barrels for many years. The Earth Minded rain barrels ahve really cheap rubber gaskets which wore over time, plus I managed to score some 30 gallon plastic barrels for conversion. This requires a much smaller hole than the plastic bulkhead fixtures and you don't have to worry about cracking from over-tightening. One minor issue is that if you want to mount a spigot using the internal thread, you will need a BUNCH of teflot tape to make this snug and seal properly. I recommend instead using a high-flow hose adapter instead - they are cheaper and mount easily. Nelson Rezimar High Water Flow Kink-Free Hose Adapter with Coil 50305

These are prefect bulkheads for plastic barrels. I have two 55g barrels full with zero drip. You just need to drill the right size hole and these should hold for many years unless you forget to drain for winter. Fits standard garden hose. I used these to connect two rain barrels about 3inch from bottom. I used an old washing machine hose between them. Works fine and sealed tight. Even if the O ring ever fails, I can just replace it.

Every rain barrel we've had has failed at the plastic fitting for the valve. These were an easy retrofit after drilling through the remnants of the prior broken fittings. Fishing the fitting into place with a wire was easy, a quick search on Youtube will show different ways of doing this if you can't access the inside of the rain barrel. They feel solid and well made, and I doubt they will be the point of failure.

Very well made! 👍

After years of fighting leaks from my Desert Spring Disc Humidifier and flush unit, I stumbled on this. Last weekend I spent 2 hours with the oem plastic fitting and could never get it to stop leaking. This nicely replaces the OEM plastic fitting on the bottom of the basin. I installed this within 5 minutes with no leaks. This works great, I wish I would have found this years ago. By an oddity of marketing, I got 2 for less than one would have cost on Amazon.

Very hard to source these but they work great, I even just ran em down by hand for a test and they sealed! The finishing work could use a little bit more effort because there are many burrs and sharp edges but good all in all

Good product buying for the second time
