Neetrue NPD-102PD Double-Wing Rain Spray Hose
Neetrue's double-wing rain-spray hose is a polyethylene tube with side wings that sprays water through rows of small holes along its length. The page heading calls it NPD-102PD and quotes 20–76 mm and a 3–9 m spray range for the family. The table below that lists seven sizes, from NPD-1203 at 20 mm to NPD-17612 at 76 mm, each with its own wall, hole pattern, working pressure, flow and laid length. To buy, pick the row that suits your field and ask Neetrue to quote that code.

Build my procurement briefOrder by table row code
The page labels the product NPD-102PD, and the material paragraph calls the range NPD-P. The table gives NPD-1203 through NPD-17612, each with its own diameter and other values. These are different hoses, so the quotation should carry one of them.
Ask for the commercial code, a hose drawing and the full table row for the roll you buy. If Neetrue confirms a row code other than NPD-102PD, use that code consistently on the quotation, packaging, connection parts and test record.

The product photo shows an NPD-1507 roll
The roll pictured on the listing carries an NPD-1507 label, which matches the 50 mm row in the table. The photo is useful for seeing the winged shape. If you are weighing the winged profile against a plain one, Neetrue's normal and double-wing rain-spray hose page sets out both.
When you order a sample, ask for a labelled roll and Neetrue's written note of which row it matches. Check that diameter, wall, hole pattern, pressure and flow all come from that same row. Then ask for the operating schedule and agree a field acceptance check on your actual layout.

Published specifications
Read each value with its stated conditions, and ask the manufacturer for any limit not listed here.
| Specification | Published value | Meaning / limit |
|---|---|---|
| Model on the page heading | NPD-102PD [1] | The size table uses seven other codes. Ask Neetrue which row your quotation covers and put that code on the order. |
| Family size range | 20–76 mm, regular sizes [1] | Each table row is one diameter. The hose you order has the single diameter of its row, set out in a row sheet or drawing. |
| Family spray range | 3–9 m [1] | The smaller table rows start at 2 m. Find out from Neetrue if the figure is the full wetted width or a one-sided throw. |
| Material | Polyethylene; Neetrue calls it virgin, UV-resistant and anti-aging [1] | Ask for the material grade and an ageing test report for the row you order. |
| Wings | Described as keeping the hose from rolling and scratching [1] | A design feature Neetrue describes in words. Ask for any stability or abrasion test if this matters on your site. |
| Flow-table unit | Printed I/min/m [1] | Ask Neetrue to confirm that it means litres per minute per metre, and at what pressure, before you calculate line demand. |
Seven sizes in Neetrue's table
Read each row as a complete set. Flow follows the source heading I/min/m. Ask Neetrue how diameter is defined, where pressure is measured and how spray range is measured.
| Row code | Published values |
|---|---|
| NPD-1203 | 20 mm diameter; 0.2 mm wall; parallel 3 holes; 0.8 bar; 2–3 m spray; flow 1.3; laid length ≤50 m. |
| NPD-1285 | 28 mm; 0.2 mm wall; slanted 5 holes; 0.8 bar; 2–4 m spray; flow 1.44; laid length ≤50 m. |
| NPD-1325 | 32 mm; 0.21 mm wall; slanted 5 holes; 0.8 bar; 3–4 m spray; flow 1.52; laid length ≤50 m. |
| NPD-1405 | 40 mm; 0.31 mm wall; slanted 5 holes; 0.8 bar; 4–6 m spray; flow 2.12; laid length ≤100 m. |
| NPD-1507 | 50 mm; 0.33 mm wall; slanted 7 holes; 1.0 bar; 5–7 m spray; flow 3.86; laid length ≤100 m. |
| NPD-1659 | 65 mm; 0.38 mm wall; slanted 9 holes; 1.2 bar; 6–8 m spray; flow 4.96; laid length ≤100 m. |
| NPD-17612 | 76 mm; 0.43 mm wall; slanted 12 holes; 1.5 bar; 6–9 m spray; flow 5.51; laid length ≤100 m. |

Plan supply and spacing from the chosen row
Working pressure, spray range and flow all belong to one row. Line spacing needs more than the maximum range, and sizing the supply for several lines needs more than one pressure figure. That supply can come through Neetrue's PVC lay-flat hose or its prefabricated-hole irrigation main pipe. Ask for the row's test conditions and a layout proposal for your field. For working pressure and friction loss on spray lines, our guide to specifying hose and pipe is a useful primer.
| Design input | What to ask Neetrue for |
|---|---|
| Available supply | Your measured pressure and flow, plus the point where Neetrue measures its rated pressure. The table helps compare rows; choosing a pump needs a pump curve. |
| Line length and slope | Planned laid length, height differences and how the supply connects. Ask Neetrue to confirm the listed maximum length for your slope and pressure. |
| Flow unit | The intended unit behind I/min/m, the pressure it applies at, and whether it is per metre or for the whole line. Settle this before calculating demand. |
| Spray measurement | How range is defined, wind and test conditions, and how water spreads along and across the line. Spacing comes from that distribution. |
| Water and filters | Neetrue's water-quality and filtration requirements and cleaning guidance for the hole arrangement on your row. |

Outdoor life, custom rolls and samples
Neetrue describes the hose as virgin material with UV resistance and more than three years of durability, and promotes savings in water, fertiliser, labour and energy. Ask for the ageing exposure test and warranty conditions behind the durability figure, and the basis of any saving you plan to count on.
The page offers custom size, colour, logo and packing. Ask how each change affects the hose specification and which test documents cover the roll you receive. Confirm diameter and connection fit, joining and repair parts, storage and handling instructions, and the current warranty. Neetrue also offers free samples; agree the sample row, freight and timing in writing.

Check a sample before the field order
Once Neetrue confirms the row code and flow unit, agree a demonstration and an acceptance test for the layout you intend to use.
Record the roll
Row code, diameter definition, wall, holes, material, length, batch label and connection parts.
Record conditions
Supply pressure and flow, line length, slope, weather and the setup Neetrue allows.
Measure distribution
Take agreed readings along and across the line and note pressure and interruptions. Judge coverage on these readings, because the widest visible spray tells only part of the story.
Match the documents
Compare the sampled roll with the current technical sheet, instructions, pressure and ageing reports and the commercial terms.

Buyer questions
Can I order NPD-102PD as one hose covering 20–76 mm and 2–9 m?
Those figures span the whole family. Each roll matches one table row with one diameter and one spray range. Ask Neetrue to quote the row you need. [1]
Does the 3–9 m headline match every row?
The smaller rows start lower: NPD-1203 lists 2–3 m and NPD-1285 lists 2–4 m. Ask for the range of your chosen row and how it is measured. [1]
Can the flow column size my pump?
It helps you compare rows. Pump sizing also needs the confirmed unit, where pressure is measured, line lengths and the full layout, so ask Neetrue for a layout proposal. [1]
Is the three-year life backed by a test?
Neetrue states more than three years of durability. Ask for the ageing test report and warranty conditions for your exact row. [1]
Does every size allow a 100 m line?
The table gives up to 50 m for the 20, 28 and 32 mm rows and up to 100 m for the 40 mm row and larger. Ask Neetrue to confirm the length for your pressure and slope. [1]
What warranty does Neetrue advertise?
Neetrue's image FAQ promises three years of warranty cover plus technical support for life. Ask for written terms covering exposure limits, exclusions, what a claim needs and replacement freight for your row. [3]
