Compatible Spray Guns for Neptune HTP Sprayers
This compatibility guide is for buyers searching for compatible spray guns for Neptune HTP sprayers on FarmingTools. It is built around products already listed in the store and evidence from supplier-backed titles, SKU mapping work, and existing collection assignments. The aim is simple: help a farmer, mechanic, dealer, or service team choose the correct spare or accessory without opening ten product pages and guessing from the photo alone.
Compatibility pages are useful only when the fitment is practical and honest. This page therefore separates confirmed matches from items that must be checked before ordering. If a machine has been modified, repaired with non-standard parts, or fitted with a different connector, shaft, guide bar mount, hose fitting, or cutting head, confirm the machine details before placing the order. That small check prevents the most common spare-part problem: buying the right product category but the wrong size or fitting.
Compatibility basis
FarmingTools has live Neptune HTP sprayer products including HTP Gold Plus, HTP Platinum, HTP 30 Gold and HTP 22 Silver. The store also has live spray gun products in the Spray Guns and Sprayer Accessories collections. The accessory listings are used as HTP sprayer buying options, with connector and pressure fitment still to be checked before installation.
The products below are linked to live FarmingTools product or collection URLs. Use the table as a buying shortcut, then open the product page to confirm the exact title, current availability, product image, and any model note shown on the listing. For farmers buying for field work, also compare the old part physically wherever possible. Matching the machine model is important, but matching size, fitting, and safe operating limits is just as important.

How to choose the right part
Start with the machine model, then confirm the size. A brush cutter blade buyer should check blade type, tooth count, central arbor, guard clearance, and whether the machine is intended for metal blades or nylon trimming. A chainsaw buyer should match bar length first, then verify chain pitch, gauge, drive links, and guide-bar mount. An earth auger buyer should match bit diameter and coupling fit. An HTP sprayer buyer should check hose diameter, pressure rating, spray-gun connector, and the way the gun connects to the lance or hose.
Do not use a spare just because the product photo looks similar. Many agricultural tools share the same general shape while using different threads, shafts, clamps, or mounts. This is especially true for sprayer accessories and chainsaw accessories. If the old part is available, compare it against the new product title and size. If the old part is missing, use the machine model page and the related collection links below to narrow the choice.
For commercial spraying, cutting, or digging work, it is usually better to keep one extra fast-wearing spare ready before peak season. A small accessory like a spray gun, hose pipe, chain, guide bar, auger bit, or blade can stop a full day of farm work if it fails during the job. This page is designed to make those repeat purchases faster and more accurate.
Replacement guidance
Replace the part when performance drops, safety is affected, or the fit becomes loose. For cutting tools, warning signs include vibration, uneven cutting, bent teeth, visible cracks, excessive heating, or a chain that needs frequent tensioning. For sprayer accessories, warning signs include pressure loss, leakage at the connector, an uneven spray pattern, trigger leakage, hose swelling, cracked hose outer layers, or nozzle blockage that does not clear after cleaning.
Before replacing, switch off the machine, remove the power source or stop the engine, and release pressure from any sprayer line. Clean the area around the fitting so dirt does not enter the pump, gearbox, carburetor, chain groove, or coupling. Tighten parts according to the machine requirement, not by force. Over-tightening can damage plastic heads, threads, seals, and hose connectors.
After installation, test the machine at low load first. For brush cutters and chainsaws, listen for abnormal vibration or rubbing. For earth augers, run the bit without digging for a short check before putting it under soil load. For HTP sprayers, test with clean water before spraying chemicals. If the accessory leaks, vibrates, or runs off-center, stop and inspect again.
Maintenance tips
- Clean soil, grass, sap, chemical residue, and dust after use so the part does not corrode or jam.
- Store blades, chains, guide bars, auger bits, guns, and hoses in a dry place away from fertilizer and pesticide residue.
- For chains and guide bars, use the correct chain oil and inspect the bar groove before heavy cutting.
- For spray guns and hose pipes, flush with clean water after pesticide or chemical spraying.
- For auger bits, check the cutting edge and spiral body after rocky or hard-soil work.
- Do not continue using a cracked, bent, leaking, or heavily worn part; replacement is safer than repair in most field-use cases.
Buying checklist before checkout
Use this short checklist before adding the part to cart. First, confirm the machine brand and model. Second, confirm the size shown in the product title. Third, compare the old part with the new product image and description. Fourth, check whether the product belongs to the correct collection, such as brush cutter blades, chainsaw chains, guide bars, earth auger bits, spray guns, or hose pipes. Fifth, if your machine has been locally modified, repaired with third-party parts, or used with a different attachment, ask for confirmation before ordering.
The best compatibility decision combines model matching with physical fitment. FarmingTools can make the search faster by grouping related products, but the final installation should always be done with normal field safety checks. Wear protective gear, use the correct guard, release pressure before sprayer work, and keep children or bystanders away from testing areas.
