Ningbo Airuiteke Irrigation Equipment
宁波市艾瑞泰克灌溉设备有限公司
Ningbo Airuiteke Irrigation Equipment is a Yuyao maker of plastic irrigation fittings: compression-type couplings, PP ball valves and pipe saddles, each in several connection versions. Its product pages give size and carton tables with sectional drawings. Choose by job first (joining pipe, isolating a line or taking off a branch), then send your actual pipe data and ask Airuiteke for current pressure ratings and dimensions for the sizes you order.
Couplings, ball valves and saddles by job
Airuiteke's catalogue is built around three jobs: joining two pipes, isolating a section with a removable valve, and taking a threaded branch off an existing main. That third job is covered by the PP pipe saddle. Each job has its own product family and its own size table. Fix the connection arrangement first; size numbers and carton counts only make sense once you know which family you are buying from.
[1][3][4][5][6][7][8][13][14]| Job in the line | What Airuiteke offers |
|---|---|
| Joining pipe | Equal and reducing couplings, tees, elbows, threaded ends, caps and a repair coupling. The equal coupling comes with a sectional drawing of the joint. |
| Isolating a section | Single- and double-union valves, internal and external threaded valves, copper-core, all-plastic and PVC valves. The PP double-union valve is listed in matched-end sizes from 20×20 to 63×63. Each valve type has its own material and rating, so ask for the sheet of the exact type you choose. |
| Taking off a branch | Threaded, hose, double-outlet and baseplate saddles. The standard saddle table pairs a main-pipe size with a branch size, up to a 160-series body. Order by the full pair. |
| Other groups | Filters, sprinklers, solenoid valves, tools and further fitting groups appear as separate catalogue links. Quote each item on its own and ask about stock for each. |
Company, brand and Macau trademark record
The contact page gives the full Chinese company name and an address in the Huangjianshan industrial area of Lizhou, Yuyao. Both match the company's registered and annual-report address. The website carries the IRRITEC and 伊瑞泰克 brand names. Airuiteke is a transliteration of the Chinese name used on this directory. Overseas irrigation firms use similar names; if ownership, licensing or group membership matters to your purchase, ask the company to state it in writing.
The Macau Official Gazette, issue 45 II of 5 November 2025, publishes trademark applications filed in September 2025 under the same Traditional-Chinese company name and Huangjianshan village address. It gives a dated record of the applicant and its location. Neighbouring applicants at the same village address are separate companies unless shown otherwise.

Quote the exact model, configuration and operating conditions together, and ask the factory to confirm current availability.
Airuiteke PP Pipe Saddle
The Airuiteke saddle clamps around an irrigation main and gives a threaded branch outlet. It has a two-part body held by bolts. The catalogue table lists 61 combinations of main-pipe size and outlet size, in 12 main-pipe groups from 20 to 160, with outlets from 1/2 up to 4. The table has no column headings, and some outlet labels are written run together, for example 11/4. To order, give your main pipe and the fitting that will screw into the outlet. Ask Airuiteke for the thread standard, a dimensioned drawing, the assembly instructions and a pressure rating for the combination you choose.
Ask the factory for the current specification sheet for this model.
Read the full specification record ↗Airuiteke PP Double-Union Ball Valve
Airuiteke's PP double-union ball valve is a manual shut-off valve for irrigation lines, with union collars at both ends and green end fittings. It comes in six matched-end sizes from 20*20 to 63*63, packed 120 down to 12 per carton. The product page includes a section drawing with dimensions marked d, d1, H and L. When you ask for a quote, give your pipe size and standard and the space around the valve. Ask Airuiteke for this valve's own pressure and temperature rating and a drawing with figures.
Ask the factory for the current specification sheet for this model.
Read the full specification record ↗Airuiteke PP Equal Coupling
The Airuiteke equal coupling joins two irrigation pipes of the same size. It sits in the agricultural PP fittings group, with a black body and green end nuts, and comes in nine sizes from 20 to 110. The table gives pieces per carton for each size, and a section drawing shows the joint with dimensions marked d, H and L. A 2019 report on three 25 mm samples (company code R1001) gives a nominal 1.0 MPa. To order, send your pipe outside diameter and standard, pick the sizes, and ask Airuiteke for the current pressure rating and a dimensioned drawing.
Ask the factory for the current specification sheet for this model.
Read the full specification record ↗Turning a size number into a pipe that fits
The coupling and double-union valve tables have two columns, Size and PCS/CTN. Their drawings mark dimensions with letters (d, H, L, and d1 for the valve) and give no figures. The tables state no unit, so a Size entry could mean pipe outside diameter, nominal bore or a thread size. Settle that for each size before you order.
[6][7][8][10][13][14]| What the page gives | What to send or ask for |
|---|---|
| Pipe side | Send pipe material, outside diameter, dimensional standard, wall and condition. Ask which pipe tolerance and end preparation the coupling or valve accepts. |
| Threaded branches | For saddles and threaded fittings, ask for thread type, size and sealing method. Strings such as 50×11/4 should come back as a clearly written order code on a drawing. |
| Outline | Ask for length, height, bore and any space needed to operate or remove the part, in figures, for the size you choose. |
| Parts and materials | Ask for the body, grip, seal, union, valve-seat and fastener materials. The PP label names the main resin; seals and other parts may differ. |
The 2019 pressure reports and your working pressure
Airuiteke shows the second page of two test reports from March 2019. Both list three samples, an appearance check and a pressure result. They tell you how particular samples performed at that date. For an order, ask for the current allowable pressure of each size at your water temperature. Our guide to specifying irrigation hose and pipe explains working against burst pressure, which helps frame that request.
[6][7][10][11]| Report | What it covers |
|---|---|
| PP straight coupling | Three d25 mm samples tested 20 March 2019, nominal pressure 1.0 MPa, static test at 1.8 × PN. The company code R1001 also appears in the equal-coupling image filename. |
| PP all-plastic ball valve | Three d63 mm samples tested 8 March 2019, nominal 1.0 MPa, company code 9001. The report does not name the separately listed PP double-union valve, so ask for that valve's own rating. |
| Full report | Only page 2 of each report is shown. Request both pages, the applicant and sample details, and the current edition of the standard the factory applies. |
| Site duty | Ask for allowable pressure against water and ambient temperature for each size, and tell the factory about pump starts, valve closing and any chemicals in the water. |
ISO 9001 certificate: expired in March 2025
The website shows a quality-system certificate in the company's name for manufacturing plastic fittings for water-saving irrigation, to an ISO 9001:2015-equivalent standard. It was issued 18 March 2022 and expired 17 March 2025. No later certificate is on the site.
If your tender needs system certification, ask for the current certificate with its site and scope, and the latest surveillance record. A system certificate covers how the factory is managed. For pressure, temperature, drinking-water use or chemical resistance of a given coupling, ask for product test reports and the documents your destination market requires.

- Stock, packing, installation instructions, lot inspection and written support terms.
Applications, materials and inspection
Airuiteke says it develops, makes, sells and supports its fittings. It names irrigation, nurseries, landscaping, greenhouses, dust suppression and emergency water repairs as uses. The site gives no plant area, machine count, output or inspection plan, so cover those in your questions.
[1][3][6][7][8][9][10][11]Material and drawing
Ask for the parts and material list, the resin or compound, and the drawing revision for the connection you buy, plus how the factory traces batches and handles substitutions.
Your water
Tell the factory your water chemistry, temperature, sun exposure and duty. Ask whether the fitting suits fertiliser, UV and drinking water, and get the answer in writing.
Inspection
Ask what dimensional, leak and pressure inspection your parts get, how samples are drawn, and how the delivered lot is recorded.
Repair and spares
Ask which seals, grips, unions, seats and fasteners can be replaced, and for the instructions. Confirm whether any product may be fitted on a line under pressure or without tools.
Building the size mix and the order file
Carton quantities fall steeply with size. The equal coupling packs 330 pieces at Size 20 and 5 at Size 110; the double-union valve packs 120 at 20×20 and 12 at 63×63. These are packing counts. Ask separately for minimum order, stock and sample quantities.
[2][6][7][8][10][11]| Order step | What to put in the quotation |
|---|---|
| Parts list | List each coupling, valve and saddle with its confirmed size, thread and build, plus any tools, seals, fasteners and spares you need. |
| Price and shipping | Ask for a current offer with packing, unit and carton weight, carton size, exclusions, destination and delivery date. The pages give no price, stock or lead time. |
| Installation and acceptance | Keep the installation instructions, the agreed lot test and the rating it is tested against with the order, and record site conditions at commissioning. |
| Documents and support | Ask for drawings for each build, quality and conformity documents, spare part codes and written support and remedy terms. |
