Import Evoh Oxygen Barrier Pex Pipe — Buy in Bulk from Supplier in China

The Evoh oxygen barrier PEX pipe supplied by Weifang Palconn Plastics Technology Co., Ltd. is a cross‑linked polyethylene pipe designed to limit oxygen permeation in water distribution systems. It is offered in nominal diameters from 16 mm to 32 mm, allowing installation in a broad selection of residential and commercial networks. The pipe is manufactured from 100 % Costab raw material and carries NSF certification, indicating compliance with recognised safety standards. The product’s barrier performance stems from the embedded EVOH layer that reduces oxygen diffusion rates to levels comparable with industry‑standard barrier pipes.

In the PEX market, typical wall thickness for 16 mm to 32 mm pipes ranges from 2.0 mm to 3.5 mm, providing the pressure ratings required for hot‑water and heating applications. Standard temperature service for such pipes is - 40 °C to 95 °C, which matches the thermal expansion characteristics of cross‑linked polyethylene. A common industry specification also includes a minimum burst pressure of 10 MPa, a figure that most certified PEX pipes, including this product, are expected to meet.

The pipe is suited for underfloor heating, potable water supply, and industrial heating loops where oxygen‑induced corrosion must be minimised. Typical buyers are plumbing contractors, building developers and engineering firms that require long‑term reliability in closed‑loop systems. While the supplier advertises flexible minimum order quantities, exact MOQ, lead‑time and incoterm details should be obtained directly from the company. Confirming payment conditions and any required documentation, such as material safety data sheets, will help streamline the procurement process.

The company is located in Yinna Industry Zone, Changyi City, Weifang, Shandong Province, China (postal code 261317). It is listed as an imported tier supplier with a harbor trust tier, and the platform data show a 0 % response rate and no recorded average response time, so proactive communication is advisable.

Weifang Palconn Plastics Technology Co., Ltd. manufactures engineering plastics, with this listing focusing on EVOH‑enhanced oxygen barrier PEX pipe. The supplier highlights its ability to offer OEM services, but does not disclose production capacity, specific certifications beyond NSF, or pricing details.
