10 Pack Bulkhead Fitting, Garden Hose Threaded 3/4 Inch Male GHT x 1/2 Inch Female NPT Double Threaded Bulkhead Water Tank Connector for Rain Barrels Water Tank Pond Aquarium Tubs Pools Spigot

Just what I needed and an excellent value too! I convert 4 gallon backpack sprayer to use for powerwashing w/pumps, after you plug the hole from the piston there's not a lot of room for a bulkhead. These have a smaller flange than standard bulkhead from the big box store or plumbing supply (in my pic the one on tge right). They have inside and regular male npt threads, they are cheap and high quality!!! Buy em!!

used to make multiple rainwater storage barrels. No issues.

Worked on my rain barrels.

I ordered this 10-pack of bulkhead fittings with garden hose threads for a rain barrel setup and some irrigation containers, and they worked perfectly. Each fitting was consistent in size and quality, making installation smooth across multiple barrels.

purchased to make home made watering soloution for my quail and chickens... the one in the picture is white but others I have made were black in color... it was easy to install, the threads were excellent, it did not leak. All in all a good value for the money

These are an amazing deal. They appear to be strong, well made fittings. The threading is excellent, and each comes with two o-rings. I needed small bulkheads to tie 4x 5.5 gallon aquariums together to a large sump, for use as an aquatic plant nursery, and I haven't had a chance to drill them yet, but these will definitely do the trick. I don't foresee any issues with leaking, the mating surfaces are flat and the o-rings seem good quality. I will likely buy these again for other tanks if they have enough flow.

Used for a custom hot water heater I made and they have withstood the temperature I was worried about

Work perfectly, great for hose connection to bucket for gravity fed low pressure watering systems. Seals well no leaking.
