Dip tube at a glance
2.4375" dip tube
Measured from the underside of the closure, where it rests on the bottle rim, straight down to the tip of the tube.
- Dip tube length
- 2.4375"
- Bottle inside depth
- About 2.56"–2.69" (tube 1/8"–1/4" shorter than the bottle)
- Neck finish
- 18-400
- Too long?
- Plastic tube; trim to length with a slight angle on the cut
Great for
- Bottles with an inside depth of about 2.56" to 2.69"
- Deeper bottles, if a little product left at the bottom is acceptable
Avoid
- Bottles shallower than 2.4375" inside, unless you trim the tube (a long tube kinks and the pump won't seat)
Tip: Measure your bottle from the top of the neck to the inside of the base, then choose a tube 1/8" to 1/4" shorter.
