What is the 50 cm lance OTH-GSP1878 and for which sprayers it fits?

LANCE 50 CM OTH-GSP1878 is a complete spray lance with a working length of 50 cm (measured from the handle to the nozzle), designed for use with handheld, backpack and trolley sprayers. It is a working element that mounts on the hose of the sprayer and ends in a nozzle responsible for spraying crop protection product, foliar fertilizers or cleaning agents.
Standard plastic connector with a diameter of 10 mm and a thread pitch of 18 mm allow easy connection of the lance to most sprayers on the market. This makes the OTH-GSP1878 model extremely versatile - it can work with both Pulmic and Keeper brand sprayers, as well as with many other devices that use a similar diameter of hose. This is a great convenience for the user, who often has several types of sprayers in one farm or company.
The lance is especially recommended for professional applications, where high precision of treatment, repeatability of spraying parameters and reliability in contact with aggressive chemicals are required. It will work well for spraying ornamental plants, vegetables, fruit trees and shrubs, as well as for weed control in paved areas and along fences.
Durable fiberglass construction - lightweight and resilient in one

The lance tube is made of high quality fiberglass. Compared to traditional brass lances, it is much lighter, which directly translates into working comfort, especially during long treatments. At the same time, fiberglass is more durable than aluminum, so the lance can perfectly withstand accidental knocks, bending or work in demanding terrain, such as dense plantings or high bushes.
Lightweight design means less strain on the operator's wrist and forearm. In practice, this allows spraying for longer periods of time without pain and fatigue, which is of great importance on farms, plant nurseries and during professional gardening services. The lance does not slip from the hand, and it is easy to control its position during precise treatments, such as spot spraying weeds between ornamental plants.
In everyday use, the difference in weight compared to metal structures is particularly noticeable when spraying tall plants or performing treatments above shoulder line, such as in fruit tree crowns, hedges or tall climbing roses. The lighter lance also makes it easier to maintain a constant distance from the surface to be sprayed, which contributes to an even distribution of the agent and higher treatment efficiency.
Viton seals - safety in working with aggressive chemicals

Handle seals are made of Viton - a specialized material with very high chemical resistance. As a result, the lance can be used with a wide range of crop protection products, herbicides, fungicides, insecticides, liquid fertilizers and cleaning formulations without the risk of rapid wear of seals or leaks at the joints.
In practice, this means safer operation for the operator and less risk of failure during the busy spraying season. Viton retains its properties at both high and low temperatures, and does not crack or harden as quickly as standard rubbers. This is especially important when working with chemical concentrates that can be aggressive to typical elastomers.
Thanks to its Viton seals, the 50 cm lance OTH-GSP1878 will work great m.in.:
- in the protection of vegetable and orchard crops when using agents with increased chemical aggressiveness,
- during professional weed control on paving stones, parking lots, access roads or maneuvering areas,
- in disinfection and washing of agricultural equipment, livestock buildings or greenhouses, where strong agents are used.
Adjustable acetal resin nozzle - precision spraying and wear resistance

The adjustable nozzle in the OTH-GSP1878 lance is made of high-quality acetal resin. This material is characterized by high abrasion resistance and very good mechanical and chemical resistance. As a result, the nozzle does not wear out quickly, maintains the precise shape of the bore and ensures stable spray parameters even after many seasons of intensive use.
Adjustability allows you to smoothly adjust the flow of liquid to your current needs:
- fine mist - ideal for foliar sprays of fertilizers and crop protection products on plants with sensitive leaves,
- medium spray cone - for standard weed spraying in flowerbeds, beds and lawns,
- concentrated spray - for spot control of stubborn weeds, spraying trunks and hard to reach areas.
In everyday use, the adjustable nozzle makes it easy to quickly switch between different types of treatments without having to change tips. For example, during one walk through the garden, you can first gently spray ornamental plants, and then strengthen the stream and thoroughly treat weeds growing between sidewalk slabs or at curbs.
Lance assembly 50 CM OTH-GSP1878 - quick connection to most sprayers

The 50 cm lance OTH-GSP1878 is designed to make its installation intuitive and does not require specialized tools. Plastic connector with a diameter of 10 mm allows direct connection of the lance to the cable of most commercially available sprayers, both handheld and backpack sprayers. The standard thread pitch of 18 mm makes it easy to replace the lance in the equipment you already have - in many cases, it is enough to unscrew the old lance and screw a new one in its place.
The lance is especially recommended for Pulmic and Keeper brand sprayers, where it is a fully compatible, manufacturer-recommended solution. It can be used:
- as basic equipment for a new sprayer,
- as a replacement part to replace a worn or damaged lance,
- as an additional lance with a different length or different nature of work, used interchangeably depending on the treatment.
For example, in a home garden, you can use the OTH-GSP1878 lance for spraying the lawn and flowerbeds, and use another telescopic lance in the same sprayer for treatments on tall trees. The universal connector makes switching between lances a snap, increasing the flexibility of the entire spray kit.
Applications of the OTH-GSP1878 lance in the home, garden and farm

LANCA 50 CM OTH-GSP1878 is a versatile tool that will be perfect for many everyday applications. Its 50 cm length is an optimal compromise between maneuverability and spraying range, making it a very practical choice for most jobs.
Typical applications of the lance:
- sprays of ornamental plants in the garden, in flower beds, in pots and on balconies,
- protection of fruit trees and shrubs from fungal diseases and pests,
- weed control on driveways, sidewalks, garden paths and along fences,
- foliar fertilizer application in vegetable and fruit crops,
- disinfecting and cleaning treatments in greenhouses, plastic tunnels and utility rooms.
In a small home garden, the lance makes it convenient to spray plants without having to bend down and get very close to each plant. On larger farms and plant nurseries, it will prove useful as a primary tool for hand-held supplemental spraying in areas where spray from tractor machines or sprinklers cannot reach.

FAQ - Frequently asked questions about the 50 cm lance OTH-GSP1878
Question 1: For which sprayers the 50 cm lance OTH-GSP1878 fits?
The lance is equipped with a plastic connector with a diameter of 10 mm and a thread pitch of 18 mm, which allows it to be connected to most hand, backpack and trolley sprayers on the market. It is especially recommended for Pulmic and Keeper brand sprayers, with which it is fully compatible.
Question 2: Is the lance suitable for working with aggressive chemicals?
Yes. The seals of the handle are made of Viton, and the nozzle is made of acetal resin, which provides high chemical resistance. As a result, the lance can be used with typical crop protection products, as well as with more aggressive herbicides, cleaning or disinfecting preparations, while observing the appropriate safety rules.
Question 3: How to adjust the spray pattern on this lance?
The liquid flow rate can be adjusted by rotating the nozzle tip. A gentle unscrewing produces a broad, misting spray ideal for foliar spraying, while a tightening of the nozzle produces a concentrated spray for spot treatments, such as single weed control or spraying in hard-to-reach areas.
Question 4: Is the length of 50 cm sufficient for spraying trees?
The 50 cm length is optimal for most daily work - it allows you to maintain a comfortable body position and provides good reach around shrubs, low trees, flowerbeds or lawns. For spraying very tall trees, you may want to consider using an additional telescopic lance, but the OTH-GSP1878 model is perfect for lower crowns and medium-height plantings.
Question 5: How to take care of the lance to make it last as long as possible?
After finishing work, it is recommended to rinse the lance with clean water to remove residual chemicals from inside the pipe and nozzle. It is also a good idea to periodically check the condition of the seals and the nozzle adjustment. Storing the lance in a dry place, away from direct sunlight and high temperatures, further prolongs its life and helps it remain fully functional for seasons to come.
