24/410 Lotion Pumps

What 24/410 means

24/410 is the small end of our neck range: 24 mm across the thread, 410 thread specification. It is the neck used wherever a 33 mm collar would look oversized — toner, serum, essence and travel-size bottles, from roughly 30 ml to 200 ml.

Because the neck is narrow, the pump body is slim too. That changes what the pump is good at: a short stroke, a smaller chamber, and a low profile on shelf. It is not the neck to choose if you need a 4 ml dose — for that, look at 28/410 or 33/410.

Which bottles use a 24/410 neck

• Toners and essences — 100–200 ml, thin liquids, 1.0–2.0 ml per stroke.
• Serums and facial oils — 30–50 ml, where the pump must dispense a controlled small dose.
• Travel and amenity kits — 30–60 ml, short dip tube, compact collar.
• Hand lotion — 200 ml, usually 2.0 ml per stroke.

Three outputs behind one neck

105 series — 1.0 ml, outer spring

A compact pump for small-dose skincare. The outer-spring layout keeps the metal out of the fluid path, and the 1.0 ml stroke means a 50 ml bottle dispenses about fifty pumps.

201 series — 2.0 ml, inner spring

The standard body-care dosage in a slim body. A machined piston chamber holds the dose steady from the first stroke to the last.

205 series — 2.5 ml, outer spring

For formulas too thick for a 2.0 ml pump — gel cleansers, hair oil, essences with a high viscosity. Metal stays outside the product channel.

Collar finish, colour and decoration

Smooth pearl white is the standard collar. Matte collars are moulded separately and listed as their own model codes in this category. Custom colours are matched against a colour chip, with silk-screen and hot-stamp available on the collar and actuator.

Dip tube, gasket and fit

Dip tubes are cut to your bottle height so a 50 ml bottle gets a short tube rather than a standard length that curls at the base. PE foam or EVA gaskets can be specified for leak-critical formulas. If you are unsure whether your bottle is 24/410 or 24/400, send the drawing — the two are close in appearance and different in thread.

Ordering and samples

MOQ is 10,000 pcs per model and closure finish. Stock samples are free for qualified projects. Bulk runs are produced in our own plant in Zhuhai, with output volume and actuation checked on every batch.
