Changshu Shangyuan Photovoltaic Technology Co., Ltd. (brand: Shangyuan PFA) is the export and sales entity of the Shangyuan PFA range, handling sales, technical communication and service for overseas and domestic markets: PFA fittings — tees, elbows, couplings, unions, threaded adapters, filter fittings and large-bore fittings — plus custom molded parts from customer drawings or samples.
Our production base, Foshan Guanqiao Precision Equipment Co., Ltd. in Foshan, Guangdong, runs precision molding machines and a Class 10,000 cleanroom; molding, inspection, assembly and packing happen under controlled conditions. With in-house precision tooling, tooling, samples and mass production are delivered in one system, with sales and factory working directly together.
Mission：Make every high-purity and corrosive fluid connection simple and reliable.
Quality system: our production base is certified to GB/T 19001-2016 / ISO 9001:2015 (production of PFA fittings and tubing). View certificate →
Sales works directly with our molding base — tooling, molding and inspection in-house, faster responses to revisions and restocks.
Inspection and packing in a Class 10,000 cleanroom, with clean bags and labels as required.
Nine fitting series with matched sizes, reducing multi-source coupling costs.
We understand what high-purity and corrosive applications truly demand: not just 'it fits', but media that stays uncontaminated and systems that stay reliable long-term. From resin selection and tool design to clean packaging, every step serves that goal.
Changshu welcomes you; overseas customers can book a video factory tour.
