Manual Sprayer Brass Nozzle M14 - Adjustable Precision Brass Spray Nozzle for Knapsack Backpack Sprayers
M14 Thread Brass Adjustable Hollow Cone Nozzle - Corrosion-Resistant, Variable Spray Pattern for Agricultural Chemical Application
Manual sprayer brass nozzle M14
The Manual Sprayer Brass Nozzle M14 is a precision-machined adjustable spray nozzle manufactured from nickel-plated brass, engineered for manual knapsack backpack sprayers requiring a durable, chemical-resistant nozzle with an M14 thread connection and adjustable spray pattern output. The nozzle comprises a hexagonal base body with internal M14 female thread for wand tip connection, a knurled cylindrical adjustment collar that rotates to vary the nozzle orifice geometry between a fine mist cone and a direct jet stream, and a precision-drilled tip insert that delivers the spray pattern determined by the collar setting. The adjustable collar mechanism gives the operator control over spray droplet size and pattern width from a single nozzle - eliminating the need to carry and swap between multiple fixed-orifice nozzle types for different crops, chemical applications, and field conditions. Brass construction provides the corrosion resistance and dimensional stability that plastic nozzles cannot sustain under prolonged contact with copper-based fungicides, acidic herbicide solutions, and high-concentration fertiliser salts - the chemical classes most corrosive to plastic nozzle materials. The nickel plating on the exterior surfaces adds a further layer of corrosion protection and reduces surface chemical adhesion, simplifying post-spray nozzle cleaning. The M14 thread standard is widely used across manual sprayer wand tip fittings from multiple manufacturers, making this brass nozzle a broadly compatible replacement and upgrade component for dealers and repair shops serving diverse sprayer brands.
Technical Profiles & Materials
1. Free-Cutting Brass Body - Corrosion-Proof, Dimensionally Stable Nozzle Construction The nozzle body and adjustment collar are machined from free-cutting brass rod - the material of choice for precision agricultural spray nozzles requiring long-term resistance to the corrosive agricultural chemicals that degrade zinc, aluminium, and plastic nozzle materials. Brass's copper-zinc alloy composition resists the chemical attack of copper-based fungicides, acidic and alkaline herbicide solutions, and fertiliser salt concentrations that cause plastic nozzles to swell, distort, and lose orifice dimensional accuracy over multiple spray seasons. The machined brass orifice dimensions remain stable across the service life of the nozzle, maintaining consistent flow rate and spray pattern geometry that plastic nozzles lose as their orifices erode and enlarge from chemical abrasion.
2. Nickel-Plated Exterior Finish - Enhanced Corrosion Resistance & Easy Cleaning The external surfaces of the nozzle body and collar receive a nickel electroplating treatment that provides an additional barrier against chemical corrosion and staining of the underlying brass, and creates a smooth, low-adhesion surface that minimises chemical residue build-up on the nozzle exterior between spray events. Nickel plating is the standard finish for premium agricultural spray hardware components that must maintain both functional performance and presentable appearance across years of chemical contact in professional spray programmes.
3. Knurled Adjustment Collar - Variable Spray Pattern from Fine Mist to Jet Stream The knurled cylindrical collar on the nozzle body is the operator's spray pattern control interface. Rotating the collar clockwise closes the orifice geometry toward a fine mist cone of small droplets suited to insecticide and fungicide canopy penetration applications; rotating counter-clockwise opens the geometry toward a coarser, higher-volume jet stream suited to soil-directed herbicide application, tank washing, and equipment rinsing. This single-nozzle adjustability allows the operator to adapt spray output to the crop, chemical, and field conditions encountered during a spraying session without stopping to change nozzle fittings - significantly improving workflow efficiency in mixed-crop or multi-application spraying programmes.

Products Application
Orchard Fungicide & Insecticide Canopy Spraying
Orchard operators applying copper-based fungicides - the chemical class most corrosive to zinc and plastic nozzle materials - benefit directly from the brass nozzle's resistance to the chemical attack that shortens the service life of standard plastic nozzle tips in copper fungicide programmes. The adjustable collar allows orchard operators to dial in a fine mist cone for maximum canopy penetration and leaf surface coverage with systemic fungicides and insecticides, then open to a coarser stream for washing nozzle equipment and spray lines between chemical programmes - without changing the nozzle fitting.
Greenhouse & Protected Cultivation Precision Spraying
Greenhouse and tunnel growers applying pesticides, fungicides, and foliar nutrients to high-value vegetable and ornamental crops require precise spray droplet size control to achieve uniform canopy coverage without excessive run-off and chemical deposition on soil and growing media. The M14 brass nozzle's fine mist cone setting produces the small, uniform droplets that maximise leaf surface coverage per unit volume of spray solution - improving chemical uptake efficiency and reducing the chemical input cost per treatment event in intensive greenhouse crop protection programmes.
Agricultural Sprayer Dealers & Spray Upgrade Market
For agricultural equipment dealers, the brass M14 nozzle is a premium upgrade product for manual sprayer customers who have experienced repeated plastic nozzle failure and are seeking a longer-service-life replacement. The visible quality difference between a precision-machined nickel-plated brass nozzle and a standard plastic nozzle tip supports a premium price point and higher per-transaction margin for dealers - while the M14 thread compatibility with widely used sprayer wand standards ensures broad customer fit without requiring customers to change their existing spray equipment to adopt the upgrade.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
