Poly Fusion Fittings

Stub End Poly Fusion Fittings

Precise Flange & Tight Fit – The flange surface uses CNC precision grinding, with high flatness and smoothness, no defects. It fits tightly after docking, sealing well enough to resist high-pressure medium impact and eliminate leaks. Occasionally, a flange might have minor flatness deviations, but nothing that affects sealing.

 

Virgin Raw Material, Pressure-Resistant & Durable – We use new virgin PE100 HDPE, no recycled plastics. Dense texture, meets GB/T13663-2018 and ISO 4427 standards, resists corrosion and impacts, perfect for high-pressure pipe networks. No heavy metal precipitation, safe for most media-we learned early on not to cut corners with recycled material.

Integral Molding, Stable Connection – Flange and pipe fitting are CNC integrally injection-molded, no splicing gaps. The root is thickened and reinforced, with strong tensile and torque resistance-no loosening or breaking, keeping the pipe network stable. Our partner contractors say this fixes the common issue of flange roots cracking under pressure.

Detachable & Reusable, Easy Maintenance – Flange docking design makes installation and disassembly easy, and it's reusable. No pipe cutting needed for later maintenance or inspection-saves a lot of time and cost, a big plus for busy job sites.

 

Full-Spec Adaptable, Strong Compatibility – Fits DN20-DN2000 full-caliber HDPE pipes, adapts to PN6-PN25 pressure grades. Accurately docks with various HDPE pipes, valves and equipment flanges, covering most installation scenarios. Only the smallest DN20 size is a bit tricky to align perfectly.

 

Strict Inspection & Traceability, Export-Adaptable – Every fitting goes through three strict inspections: water pressure sealing, flange flatness, appearance flaw detection. Unqualified products stay in the factory, each comes with an exclusive test report. Supports CE and SGS certifications, quality traceable-ideal for foreign trade and high-end projects. We're working on adding more regional certifications per client requests.

This is our flange HDPE pipe fitting, core for HDPE pipe network flange docking. Designed for scenarios needing disassembly, inspection and high-pressure sealing-flange surface is precise, connection firm and sealed tight. It's widely used in municipal water supply and drainage, industrial park high-pressure pipelines, water conservancy projects, etc.

Selected virgin PE100 HDPE, no recycled materials, dense texture, meets dual international and domestic standards. Excellent acid and alkali, corrosion, impact and creep resistance, no heavy metal precipitation-safe for drinking water, industrial chemical fluids, high-pressure irrigation, etc. For super corrosive media, check with our tech team first.

CNC integral injection molding means no splicing gaps; root thickening resists high-pressure impact and pipe displacement, no loosening or breaking. CNC precision-ground flange surface ensures tight sealing, eliminating leakage risks entirely-way more reliable than cheap, spliced flanges.

Compatible with DN20-DN2000 HDPE pipes and PN6-PN25 pressure grades, docks accurately with pipes, valves and pumps. Flange design enables easy, reusable assembly; no pipe cutting for maintenance, shortening periods and reducing costs. The largest size is a bit awkward to maneuver alone, so two people are better.

We control quality strictly-three inspections, no exceptions. Each fitting has a test report, full quality traceability, and international certifications (CE, SGS) to meet foreign trade and high-end engineering standards. This strictness keeps our repeat clients coming back.

Bulk customization is available-different calibers, pressure grades and flange specs, just send your drawings. We provide CAD specs and technical support. Overseas clients get FOB/CIF delivery, one-on-one follow-up for installation/transport questions. Plan ahead for custom orders to avoid rush stress.

Qingdao Polyfusion Machinery Co., Ltd. holds that high-performance raw materials are the fundamental prerequisite for manufacturing top-tier HDPE piping systems. In the production of all our HDPE pipes and fittings, we have always adhered to the strict standard of selecting premium raw materials from well-known manufacturers around the world. These raw materials we adopt have been widely recognized as the high-grade base materials for HDPE pipe fitting production by professionals in the plastic piping industry.

The outstanding performance and ultra-stable physical and chemical properties of these raw materials are the core driving force for our products to maintain excellent quality. It is precisely relying on the superior quality of these raw materials that our HDPE pipes and fittings have firmly established a high-quality market position in the industry, and can consistently provide our cooperative partners with reliable and high-standard piping product solutions.

We adopt high-strength, shock-resistant, pressure-proof and wear-resistant packaging materials, and implement classified fixed packaging for different sizes and types of fittings to avoid collision, scratch and deformation during long-distance transportation and multiple handling. All packages are clearly marked with detailed product information, batch numbers, loading and unloading notes and shipping marks, which greatly facilitates your warehousing, sorting and subsequent construction use.
