Quality Certificate
SUNPLAST always sticks to the managing guideline of “manufacturing excellence”, and commits to provide our customers the HDPE fittings on best quality. All fittings meet the highest quality requirements as stipulated in ISO9001, ISO14000:14001 guidelines and our stringent quality control system.
All HDPE fittings have passed the National Chemical Building Materials Test Center tests, and all performance are in line with ISO4427-3/EN12201-3 standard, as well EN1555 standards. At the same time, the fittings are also approved by ISO4427 certificate, CE certificate for EN12201.,etc

Advantages Of HDPE fittings
The reason why HDPE pipe has become the most common solution for water plumbing, a reliable HDPE fittings play a important role, as there are many advantages as below:
* The HDPE fittings, including HDPE butt fusion fittings & HDPE electrofusion fittings, are thermal plastic fittings. The pipeline & fittings can be welded together in a heat-fusion technology by using a special welding machine, which creates a fusion joint that is leak-free and as strong as the pipe.
* Can provide variety of choice. The HDPE fittings include different type of fittings for pipeline, such as HDPE butt fusion fittings, HDPE electrofusion fittings, HDPE compression fittings, Mechanical fittings..etc. People can take the best choice based on their budget, construction environment.
* Safety of potable water: HDPE fittings are made of PE100 material, which is hygienic and suitable for portable water transportation.
* Resistance to corrosion, tuberculation, deposits: HDPE fittings are free to corrosive mediums.
* Freeze-break resistance: HDPE fittings can support working environment at extreme low temperature, no break.
* 50 years’ lifetime design: HDPE fittings are designed for 50 years use for regular use.
* Recyclable, eco-friendly material: HDPE material is recyclable, and friendly to economic.
Technical Parameter
The HDPE spigot fittings are manufactured into our domestic standard of GB/T13663, and international standard ISO4427-3 standard. The HDPE butt fusion fittings are strictly tested as per the standard, and shall satisfy the technical parameter as below:

FAQS

* What’s the difference between HDPE tee fittings & HDPE cross fittings?
A: HDPE tee fittings have 3 branches, while HDPE cross fittings have 4 branches.
* Is SUNPLAST HDPE fittings UV resistant?
A: Yes, HDPE fittings made in black color are UV resistant and UV stable and will not structurally degrade from UV light. After a lengthy period of direct UV light contact, the external surface of the fittings change visually to a slightly waxy look, but this does not affect the performance and is removed by a rotary pipe scraper prior to electrofusion welding.
* Are SUNPLAST HDPE butt fusion fittings available to weld with HDPE electrofusion coupler?
A: Our HDPE butt fusion fittings are designed for butt fusion only, and don’t have enough length for electrofusion.
SUNPLAST can also provide long-spigot fittings, which is suitable for welding with HDPE electrofusion coupler. If customers need it, please contact us freely.
* How can SUNPLAST satisfy a fast delivery requirements?
A: To satisfy our customers urgent need requirements, SUNPLAST has stocked large quantity of fittings in stock. Most regular sizes are available in our stock.
So, whatever small quantity order for LCL shipment or big quantity order in full container, SUNPLAST can satisfy all your requirements.
* What’s the warranty can SUNPLAST provide?
A: All our HDPE fittings are made of virgin PE100 material, and are designed for 50 years lifetime. SUNPLAST will provide a warranty time in quality of 10 years for regular use.
