Perfume Bottle Pumps: Crimp vs Screw Neck Guide 2026

Choosing the right perfume bottle pump locks in everything that follows: how the spray feels, whether the unit survives shipping, and whether the bottle can ever be refilled. The established answer in fine fragrance is a crimp-on perfume bottle pump, where an aluminium ferrule is pressed permanently onto a 15 mm or 18 mm FEA neck. Refillable and travel formats use a threaded screw-neck pump the user can unscrew. Decide the system first, then match the bottle neck, pump collar, cap and crimping tool to one shared size code.

What Is a Perfume Bottle Pump and How Much Does It Dispense?

A perfume bottle pump is a precision dispensing assembly rather than a simple spray head. Four parts do the work: the actuator the user presses, the housing that holds the spring and valves, the stem that travels into the neck, and the dip tube that reaches the liquid. Inside, a pressure differential turns fragrance into a fine mist of consistent droplets. Because the whole assembly is sized to the neck, a perfume bottle pump cannot be chosen independently of the glass.

Dosage per stroke shapes the user experience. Published industry guidance puts crimp pump output at 0.07–0.14 ml, while one large neck-size survey reports a common 0.1–0.15 ml band. Manufacturers standardise dosage so buyers choose predictably: 60 μL, 70 μL and 100 μL are the usual catalogue options, and the same catalogue advises calculating sprays per bottle before committing.

A 50 ml bottle holds roughly 50,000 μL, so a 70 μL pump delivers about 700 sprays and a 100 μL pump about 500. Lower dosage suits concentrated extraits where each spray carries more oil; higher dosage suits eau de toilette and body sprays. The dip tube must still reach close to the base of the bottle: too short wastes fragrance, too long kinks and blocks flow. Every perfume bottle pump in our custom perfume bottle range ships with dip tubes cut to the bottle height, so dosage and dispensing stay consistent to the last spray.

Crimp vs Screw Neck Perfume Bottles: How Each Seal Works

The difference between crimp and screw perfume bottles starts in the glass, not the pump. A crimp neck is smooth and straight with a raised ridge moulded around it. The perfume bottle pump sits over the neck and a metal collar — the ferrule, usually aluminium — is pressed down around that ridge, so the metal deforms into the groove and locks the pump on permanently. The gasket sits under factory-set preload for the life of the bottle, so nothing the customer does later affects the seal — which is why the format dominates retail fine fragrance and is inherently tamper-evident.

A screw neck carries continuous threads moulded into the glass, and the pump seals by friction: thread engagement plus tightening torque compress the gasket. The seal can be excellent, but it is a maintained one: vibration in transit, thermal cycling and handling relax the preload, so quality depends on thread tolerance, gasket choice and assembly torque — variables controlled at the factory rather than guaranteed by geometry. A perfume bottle pump selection guide from Jarsking makes the same point from the manufacturing side: crimp-on systems tolerate minor neck variation, while threaded systems live or die on tolerance control.

A third option sits between the two. Crimpless (self-crimping) pumps are pushed onto the neck and held by an interference fit, needing no machine — a real advantage for small batches without a crimping press. They offer no tamper evidence and removal destroys the pump, so fine-fragrance lines rarely adopt them.

Closure system	How the seal is made	Reversible?	Typical neck
Crimp-on	Ferrule plastically deformed around the neck ridge	No — permanent, tamper-evident	FEA15, FEA18
Screw-on	Threads plus assembly torque compress the gasket	Yes — refillable	15/415, 18/410, 18/415
Crimpless	Interference fit from push-on seating	No — removal destroys the pump	Push-on equivalents

Perfume Bottle Pump Neck Sizes: FEA15 vs FEA18 and GPI Thread Codes

Product pages rarely print the words crimp or screw. They print a code, and ordering the wrong side of a slash is how fit failures happen. FEA15 and FEA18 are crimp-neck sizes. The FEA series takes its name from European Aerosol Federation standards (the same dimensions appear in EN 14854), and the number states the neck diameter in millimetres. FEA15 is the workhorse of fine fragrance, commonly used from 10 ml up to roughly 50 ml; FEA18 appears more often on 75–100 ml formats and above. A pump neck-size guide from Packamor puts the same split plainly: FEA15 is most common up to 50 ml, FEA18 typical for 100 ml and above. Other diameters exist — 13 mm, 18 mm and 20 mm all appear in crimp-on ranges.

The critical trap is assuming capacity predicts the neck. It does not. Some 100 ml bottles run FEA15, and only the supplier’s specification confirms which. GPI thread finishes are the screw-neck language, written as two numbers: neck diameter in millimetres, then the thread form. In the continuous-thread family used across cosmetics, 410 means one and a half thread turns and is the most common sprayer finish, while 415 means two full turns with deeper engagement and a stronger lock, favoured where leak prevention matters most. So 18/410 and 18/415 are both 18 mm necks but not interchangeable — a collar may screw on yet never seat.

Code	System	Typical use	Must match
FEA15	Crimp neck, 15 mm	10–50 ml fine fragrance	Crimp pump, ferrule, FEA15 crimper
FEA18	Crimp neck, 18 mm	75–100 ml and larger	Crimp pump, ferrule, FEA18 crimper
15/410, 18/410	Screw neck, 1.5 turns	Standard sprayer finishes	Threaded pump with the full code
18/415	Screw neck, 2 full turns	Refillable, travel, leak-critical	Threaded pump with the full code

One rule prevents most ordering failures: crimp pumps and screw pumps are physically incompatible. A threaded collar cannot grip a smooth crimp ridge, and a ferrule cannot bite threads. Lock all four elements to the same code — bottle neck, perfume bottle pump collar, cap, and crimping tool — then confirm with stock samples before a first production order. For sample and travel formats this matters twice over, which is why our 5 ml perfume tester bottle and sample and travel perfume bottle collections are quoted with their matched closures rather than as bare glass.

Filling, Crimping and Seal Testing a Perfume Bottle Pump

Fine-fragrance production has a fixed order of operations, and reversing it creates rework. Sequence and test method both come from published crimping guidance, including Packamor’s crimping guide.

1. Fill before crimping. Leave roughly 5–10% headspace so the liquid can expand thermally. Once crimped, the bottle cannot be filled without destroying the pump.
2. Insert the dip tube and seat the pump. The tube should reach near the bottom of the bottle, and the pump sits loosely on the neck at this stage.
3. Position the ferrule squarely. An off-centre collar produces an uneven crimp and a leak path, so alignment is verified visually before any force is applied.
4. Apply the crimp with matched tooling. A bench crimper or automated press applies consistent force and timing; hand crimpers and improvised tools concentrate force unevenly, causing cracked necks and slow-evaporation leaks.
5. Test the seal. Invert the filled bottle overnight, actuate the pump five to ten times to prime it, confirm an even spray pattern, and check that the ferrule shows no flex or movement when pressed.

MOQ, Cost and Sourcing Checks Before You Order a Perfume Bottle Pump

Published supplier guidance puts stock 30 ml, 50 ml and 100 ml bottles at roughly 3,000–10,000 pieces, while custom moulds become economical from about 30,000–50,000 pieces. Below that, the proven route is a stock bottle differentiated by collar, cap, coating and print — how most niche brands launch without tooling risk. On unit cost, a crimp-on perfume bottle pump typically costs less per unit than a screw-on or snap-on alternative, so choosing a threaded neck for a refillable story adds cost as well as seal-management work.

The collar is where premium perception is bought. Aluminium is the standard ferrule material, with zamac or brass for premium programs and anodising available in any colour. One discipline matters here: a collar profile change can require a different pump skirt, so collar, pump and actuator are quoted as a set. Two logistics points belong in the spec file: alcohol-based fragrance is Class 3 flammable for freight, and EU and US labelling requirements differ — list both before pricing.

Before placing a purchase order, run this checklist against the supplier’s specification sheet:

• Neck type confirmed as crimp or screw, with the full size code (FEA15, FEA18, 18/415)
• Perfume bottle pump dosage confirmed in μL, with sprays per bottle calculated
• Dip tube length matched to bottle height
• Collar material, colour and profile locked with the pump skirt
• MOQ quoted separately for stock, custom finishing and new moulds
• Water or alcohol seal test completed before filling fragrance
• Crimping tool size matched and validated on a test run

The neck decision is normally made once and reused across a portfolio. Our 100 ml luxury gold rectangular perfume bottle and 50 ml and 100 ml cylinder perfume bottle with magnetic cap are supplied with a matched perfume bottle pump and collar, and the same matched-set approach extends to attar bottles and the wider glass bottle catalogue.

Match the Perfume Bottle Pump to the Bottle Before Tooling

The decision order for any fragrance launch is fixed: choose crimp or screw by how the bottle lives — sealed retail unit or refillable format — then match neck code, pump dosage, collar and cap to that single system, and only then consider moulds and volumes. Getting it in the wrong order is expensive, because a neck that cannot accept your pump invalidates the tooling around it. To confirm the right perfume bottle pump and collar pairing for your format, send us your bottle neck specification or a photo of the neck, and we will return the matched pump, collar and cap options with MOQ and lead time.
