A stainless steel fire hose lance is a handheld or system-mounted outlet component that directs water or another approved extinguishing medium from a hose or sprayer toward a target. The right choice depends on the application, operating pressure and flow, connection type, material grade, and the required discharge pattern. Before ordering, match the lance to the complete system—not just the hose diameter—and confirm that its documented limits and wetted materials suit the intended medium.

This guide is for agricultural equipment buyers, fire-fighting sprayer manufacturers, equipment integrators, and procurement teams comparing lance options. We explain what to specify, how to check compatibility, and what information to request from a supplier such as Kobold. The examples below are for illustrating a selection process; they are not product ratings or performance claims.
A lance provides a controlled outlet at the end of a hose or pipe assembly. Depending on its design, it may direct a stream, provide a selectable spray pattern, or connect to a separate nozzle that performs the final flow control. The term “lance” can describe different configurations, so buyers should verify whether a quoted item includes a nozzle, shut-off valve, coupling, or other fittings.
In agricultural and fire-fighting sprayer systems, the lance may be used for targeted water delivery, equipment integration, or other applications defined by the system designer. Its performance is affected by the pump, hose, fittings, nozzle, fluid, and operating conditions. A lance alone cannot establish the output or suitability of the complete assembly.
Stainless steel is commonly selected where buyers want a metal component with corrosion resistance, cleanability, or mechanical durability. The grade matters: 304 and 316 stainless steel are distinct material options, and the more suitable grade depends on the fluid, environment, cleaning method, and exposure conditions. Do not assume that any stainless steel grade is compatible with every chemical, foam concentrate, or cleaning agent.
Ask the supplier to identify the proposed grade for each wetted component, including the tube, body, valve, and fittings. Also check seals and other non-metal parts, because they can determine fluid compatibility and service life. If the application involves additives or chemicals, provide the product name and concentration for a compatibility review rather than relying on a general “stainless” description.
Connection mismatch can prevent installation or create leakage, even when the nominal hose size appears correct. Specify the connection standard and gender at both ends, along with thread size, pitch, sealing method, and any coupling profile required by the existing system. NPT and BSP threads, for example, should not be treated as interchangeable without confirmation of the actual design and sealing arrangement.
If the lance connects to a proprietary coupling, send a drawing, part number, or clear photographs with measurements. State whether adapters are acceptable, since an adapter can add length, weight, or another potential leak point. Ask the supplier to confirm the interface in writing before production or shipment.
Start with the job the lance must perform, then work back to the hardware. Identify the medium, expected operating conditions, target distance or area, required spray or stream behavior, and how the operator will handle and store the assembly. These details help distinguish between a simple outlet tube, a lance with a control valve, and a lance paired with a dedicated nozzle.
Do not select based on appearance or material alone. A polished stainless tube does not prove a pressure rating, chemical compatibility, or suitability for a particular fire-fighting system. Those characteristics must be confirmed for the exact configuration offered.
Document the working and maximum pressure specified for the system, the required flow, and the medium being discharged. Provide normal and worst-case operating conditions where known, including temperature and any relevant cleaning or storage exposure. The pump and system designer should establish these requirements; the lance supplier should then confirm whether the proposed assembly is rated for them.

Record the required overall length, tube diameter if constrained, handle or grip preference, and the desired outlet configuration. For example, a buyer might use 600 mm as an illustrative target length when preparing a drawing, but this is not a universal recommendation. Confirm the finished dimension and tolerances against the installation and operator needs.
Decide whether flow control is needed at the lance or elsewhere in the system. If a nozzle is included, specify the desired pattern and whether it must be adjustable or fixed. Avoid assuming that an outlet shape or nozzle description guarantees a particular reach, flow, or droplet pattern; request relevant configuration details and supporting documentation.
Use the system’s actual design requirements, not a generic value found in an online listing. As an illustration of how to write a purchasing brief, a buyer could state a maximum operating pressure of 10 bar and request supplier confirmation; this figure is an example only, not a recommended or Kobold product rating. Likewise, a stated demand of 100 L/min can serve as an example input for a flow discussion, but the actual requirement must come from the system design.
Ask the supplier to identify the pressure basis for the quoted assembly and clarify whether any rating applies to the lance alone or the complete assembly with fittings and seals. Request confirmation of the connection standard, material grade, and included components. If there is no documented match, do not treat the item as approved for use.
Price depends on the configuration being quoted, including material grade, dimensions, connection requirements, valve or nozzle inclusion, finishing, and order quantity. Custom interfaces or documentation requirements may also affect the quotation. Share a complete specification so suppliers can price equivalent products rather than comparing unlike configurations.
Minimum order quantity and lead time vary by supplier, product configuration, and production schedule. We recommend requesting these details alongside the unit price, sample availability, packaging, and shipping terms. For a custom project, confirm whether drawing approval or a first-article review is required before placing a volume order.
For B2B sourcing, clear records reduce ambiguity between the purchase specification and the delivered assembly. Keep the approved drawing, material description, connection details, and agreed operating requirements with the purchase order. If a product is intended for a regulated or safety-critical system, have the responsible engineer verify project and local requirements before procurement and use.
Kobold serves buyers in agricultural equipment and fire-fighting sprayer manufacturing who need to evaluate stainless steel lance options for an equipment or sourcing brief. Share your application, fluid, pressure and flow requirements, connection details, target dimensions, and expected quantity. With those inputs, we can review the requested configuration and clarify what information is needed to prepare a quotation.
For a new or replacement assembly, include photos or a drawing of the existing connection and explain which components must be supplied. If you are still defining the specification, we can help organize the questions that need confirmation, while the system designer remains responsible for establishing safe operating requirements. This approach helps keep the quotation aligned with the intended equipment rather than relying on assumptions.
The best stainless steel fire hose lance is the one whose material, dimensions, connections, pressure and flow limits, and outlet configuration match the complete system and application. Confirm fluid compatibility and interfaces, and request documented ratings for the exact assembly instead of inferring performance from its material or appearance. Before buying, prepare a concise specification and have the responsible equipment designer approve the configuration.
To request a Kobold quotation, send the application, medium, operating requirements, connection standard, required dimensions, preferred configuration, and order quantity. If any details are unknown, identify them as open questions so they can be reviewed before the order is finalized.
