Gallon Pump Dispenser - Dispenses 1 Ounce Per Stroke - for Plastic or Glass Bottles – Heavy-Duty Leak Proof for Commercial and Household Use – BPA Free 38/400 (Pack of 4)

Using these in our grooming shop (2sheps.com) and they work great. The shampoo and conditioners for pets come super concentrated and thick. These pumps fit the bottles perfectly and easily handle pumping the thick liquids.

These pumps are of excellent quality! They fit my gallon-sized horse supplements perfectly. It also works well on a 30oz bottle. I had a more challenging time fitting it and working with my canola oil gallon-sized bottle. It will leak sometimes after a pump, but that's my only issue. It works great depending on the liquid used. I will repurchase it when I need more. Great price for how many you get.

For snowcones I like it because its great to use and no dislike.

The original ones I bought a few months back worked great so I got a few more. But, the newer ones would not screw onto the bottles (crooked and not well seated) and the pump would not unlock. Then I noticed they looked different than the original ones - like they came from a different manufacturer. I checked to be sure I ordered them from the same place - which I confirmed). Basically, the newer ones are unusable.

I purchased the 2-pack of these pumps. The first one screwed right onto my gallon soap jug perfectly. The other one didn't quite fit the gallon jug of hand sanitizer I have but the pump mechanism actually comes apart and I was able to cut a hole in the cap of my sanitizer jug and use it with the new pump for a perfect fit. I appreciate the flexibility of it being customizable.I also appreciate how much liquid this pump dispenses with each push. I'm refilling my 8 ounce hand soap dispensers and this refills them quickly with minimal pumping. My old dispenser required dozens and dozens of pumps to refill. This new pump only requires a handful of pushes to completely refill the dispensers.

They work fine, but they leak bad!!

Use these for my homemade shampoo and conditioner.

The design of the pump causes the plastic valve inside to break and prevent the pump from working. There is a plastic spacer with a small bearing and over time of compression, the plastic piece compresses and prevents suction in the pump. It lasts about 6 months of pumping. Use to pump insecticide in 1 oz increments. Average 400 pumps a week

These fit the 1000ml bottles of Redken perfectly.

Faltaron 3 cilindros de plástico

La boîte est arrivé très abîmé et puisque les pailles n'étaient pas attaché ensemble il m'en manque une... Assez plate

It was recommended to us with redkin 1l bottle, but they don't fit! Conference is waytoo big for any redken 1L bottles!

I'm using it for a pump on my 1L dish soap bottle that I also use to wash my hands. It's heavy plastic top looks quite durable. The spare is handy too.
