Spray Bottle Nozzles

The spray bottle nozzle is the most mass-produced nozzle there is, and the one most people never think about, until the pattern is wrong, the output is weak, or the new head will not screw onto the bottle they already have. For a trigger sprayer, three things decide whether it works: the output per stroke, the pattern, and the thread.

This is the consumer and janitorial end of the nozzle world, low pressure, hand actuated, and sold by the thread standard more than by the spray. The range on this page runs from a fine mist that wets evenly to a stream that targets one spot, all four models on the same 28/410 fit.

Output and Pattern

Output is the liquid delivered per stroke, set by the orifice and the dip-tube check valve. A fine-mist trigger throws less per pull but covers a wide soft cone; a stream trigger throws a directional jet for targeted application; a foam trigger entrains air to lay a clinging foam.

The pattern has to match the job. Disinfection and detail cleaning want a fine cone that wets a surface evenly without pooling; degreasing a specific part wants a stream; oven or glass cleaner often wants foam that clings instead of running off.

The Thread Standard Decides Fit

The 28/410 thread is the de facto standard for trigger sprayers and most consumer bottles, and it is why a replacement head from one brand usually fits a bottle from another. The “28” is the neck diameter in millimetres; the “410” is the thread finish. A nozzle that is not 28/410 will not seat, regardless of how good the spray is.

That single dimension is the most common cause of “the new spray head does not fit my bottle”, the bottle is a different finish, not a different brand problem. Read the finish code moulded into the neck, or measure the neck diameter with a calliper, before buying a replacement head.

Pressure Is Hand Actuation

Unlike every other nozzle on this site, a trigger nozzle runs on hand pressure, not a pump or line. Output and pattern are bounded by what a finger can generate, which is why these nozzles are tuned for low actuation force and a consistent cone rather than high flow. Trigger output across the industry sits in the 0.3–1.2 mL per stroke band, and the tip pressure is a fraction of what an industrial line nozzle sees.

That also means wear shows as a weak or uneven pattern long before failure, the spring and check valve fatigue, and the cone goes lopsided.

Range Walkthrough

The reference table above lists the range in one view; this section says when each model is the right answer. All four heads share the 28/410 thread and a PP body, so the choice between them is really about output per stroke and pattern.

SB-STD (standard trigger): the default of the range. 0.4–1.0 mL per stroke through a wide, even cone, for all-purpose cleaning where you want good coverage per pull without atomising the product into a drift. If the duty is a generic household or janitorial cleaner, this is the head to start from.

SB-FINE (fine mist trigger): the lowest output at 0.3–0.8 mL per stroke, delivered as a fine cone that wets evenly without pooling or running. This is the disinfection and plant-misting head: fine droplets cover more surface per millilitre and hold on the surface long enough to work, which matters for sanitisers that depend on contact time.

SB-JET (jet trigger): the highest output at 0.5–1.2 mL per stroke, thrown as a directional stream rather than a cone. For targeted application: degreasing a specific part, flushing a crevice, washing down a surface you do not want to soak. Same fit as the rest of the range, a different job.

SB-FOAM (foam trigger): 0.5–1.0 mL per stroke of liquid, but the head meters liquid and air separately and mixes them at the mesh, so what lands is a clinging foam rather than a spray. For vertical and inverted surfaces, oven walls, glass, bathroom tiles, where a liquid would run off before it has time to work.

Application Matrix

Application	Typical duty	Recommended model	Why
All-purpose surface cleaning	Kitchens, desks, general wipe-down	SB-STD	Wide cone covers a surface in one pass
Disinfection and sanitising	Contact-time sanitisers, healthcare surfaces	SB-FINE	Fine cone wets evenly without pooling, better coverage per mL
Glass and mirror cleaning	Streak-free glass, chrome, stainless trim	SB-FOAM	Foam clings to vertical glass instead of running off
Degreasing and parts washing	Workshop parts, stove tops, grilles	SB-JET	Stream concentrates the chemical on the soiled spot
Oven and bathroom cleaning	Baked-on grease, limescale, soap scum	SB-FOAM	Clinging foam holds the active on the surface longer
Gardening and plant care	Foliar misting, seedling watering	SB-FINE	Fine droplets cover leaves without drenching or shocking
Car care and detailing	Interior trim, tyre dressing, glass	SB-FINE	Low output avoids overspray in tight interior spaces
Pet care and spot treatment	Coat sprays, stain spot-cleaning	SB-STD	Even cone with enough output to wet a patch quickly

Three-Step Selection

If the full checklist feels heavy, the decision collapses to three questions:

1. What is the job? Decide whether the surface needs even coverage, a targeted spot, or a liquid that clings. That answer names the pattern family: fine mist for wetting, standard cone for coverage, stream for targeting, foam for vertical and inverted surfaces.
2. Which pattern? Match the family to the model: SB-FINE, SB-STD, SB-JET or SB-FOAM. Output follows the pattern: fine mist throws the least per pull, the jet the most.
3. What fits? Confirm the thread, 28/410 is the standard, and the neck moulding or a calliper check settles it in seconds, then check the output per stroke against the liquid. Water-thin sanitisers suit the fine mist; viscous fills need a larger-orifice head.

Reference Specifications

Output is per stroke at typical hand-actuation pressure; thread is the bottle fit. Figures are compiled from public industry sources as a sizing starting point, not a datasheet.

How to Select a Spray Bottle Nozzle

• Pattern versus job: fine cone for even surface wetting, stream for targeted application, foam for clinging.
• Thread: confirm 28/410 (or the bottle’s actual finish) before buying a replacement head; fit is decided here.
• Output per stroke: set by orifice; match to the liquid and the coverage needed.
• Chemical compatibility: PP bodies handle most cleaning and disinfection fluids; check aggressive solvents against the seal material.
• Spray quality: a consistent, symmetric cone is the sign of a good trigger; lopsided pattern means worn internals.
• Replacement logic: triggers wear in the spring and check valve; a weak or uneven cone is the cue to replace, not just refill.

Frequently Asked Questions

Why won’t the new spray head fit my bottle? Almost always a thread mismatch, not a brand issue. Confirm the bottle is 28/410 or match its actual finish.

Fine mist or stream for disinfection? Fine cone for even surface wetting without pooling; stream only when you are targeting a specific spot. Disinfection usually wants the cone.

Why is my trigger sprayer pattern lopsided? Worn spring or check valve inside the trigger. The head is fatigued, not clogged, replace the trigger.

Can I use any trigger on any bottle? Only if the thread finish matches. 28/410 is the common standard, but bottles outside it need the matching head.

How many millilitres does one pull deliver? Roughly 0.3–0.8 mL for a fine-mist head, 0.4–1.0 mL for a standard trigger, 0.5–1.2 mL for a jet, and 0.5–1.0 mL of liquid for a foam head, which adds air, so the wet dose looks smaller than the foam volume. The number is in the head spec, not the bottle spec.

Why does my trigger need several pulls to start? The check valve at the bottom of the dip tube has worn, or the tube has pulled up out of the liquid. If the head is new, check the tube seating; if it is old, the valve has fatigued.

Will bleach destroy the trigger? Short contact, usually not; long-term storage of concentrates in the bottle can attack the elastomer seal. Use a head rated for the oxidiser concentration and never store concentrates in the sprayer between uses.

Can I get a custom trigger for a private-label bottle? Yes, heads are made to the bottle finish, with output range, pattern and seal material set to the product. That is an OEM conversation: send the bottle spec and the target chemistry through the enquiry form.
