Why YILON
A zipper factory that publishes its numbers
Airtight zippers are not a commodity — two suppliers can both quote “IPX8” and still perform completely differently under pressure. Here is what we make public.
Manufacturer, not a trading house
A National High-Tech Enterprise founded in 2014, with its own R&D team and multiple patents. You are quoting the factory.
IPX6–IPX8, with test reports
Full-range waterproof rating testing. Airtight builds additionally carry a 60 kPa sealing-pressure test with factory reports included.
Full customisation
Size #5/#8/#10, chain width 35–70 mm, length 5 cm–100 m, colour, slider and opening style — all produced to your project.
Process matched to your material
HF welding, sewing with seam tape, and bonding. The assembly method is chosen to suit the host material and sealing grade.

Common questions
Technical questions buyers ask first
Full answers to these and many more are on the FAQ page.
What is an airtight waterproof zipper, and what sealing problems does YILON solve?
An airtight waterproof zipper stops water, air and moisture entering or escaping through an opening. It suits products that need an openable sealed port: military equipment, waterproof equipment, sealed bags and luggage, protective suits, diving gear, inflatable products and industrial high-speed doors. YILON can customise length from 5 cm to 100 m, plus size, tape width, colour, slider, opening style, material and testing requirements.
How do I choose between #5, #8 and #10 airtight waterproof zippers?
#5 suits lightweight and flexible products, #8 suits medium-to-high strength waterproof equipment, and #10 suits heavy-duty, pressure-resistant and industrial sealing projects. The resin, nylon woven, self-healing and circular ranges address military equipment, waterproof equipment, sealed bags and luggage, and protective suits. When selecting, supply the use case, opening length, tape width, host material, water or air pressure, opening frequency and target waterproof rating.
What do the IPX6, IPX7 and IPX8 waterproof ratings mean?
IPX6 means protection against powerful water jets, IPX7 means protection against temporary immersion, and IPX8 means continuous immersion under agreed conditions. When selecting, define the test depth, pressure, duration, mounting method, end structure and whether the zipper must be opened and closed repeatedly.
What parameters do I need to provide to customise an airtight waterproof zipper?
To customise an airtight waterproof zipper you need to provide the use case, length range (5 cm to 100 m), effective opening length, size or tape width, colour, opening style, slider count, host material, waterproof rating, oil resistance requirements, sample quantity, trial production quantity and mass production quantity.
How long do sampling and mass production take?
Typical reference: sampling is about 7–15 days and mass production is about 15–30 days, depending on specification, material and quantity, subject to confirmation by the manufacturer. It is advisable to confirm both the sampling and production lead times at the time of enquiry.
What is the minimum order quantity (MOQ)?
The minimum order quantity depends on the specification and material; there is no single figure. Provide your estimated quantity with your enquiry and YILON will confirm it against your specific project.
