- Product Introduction
The Threaded Pipe Coupling is processed by high-precision CNC machine tools to ensure that the thread meshing degree reaches a tolerance of ±0.01mm. The embedded sealing structure can adapt to the thermal expansion and contraction of the pipeline, and there is no risk of loosening during long-term use. We offer a full range of products from low-voltage civil (PN6) to ultra-high-voltage industrial (PN250) to meet the demands of extreme working conditions.
Product Type
Classified by thread standards
Metric thread (M) : Complies with ISO standards and has strong versatility
British standard threads (NPT/BSP) : American standard NPT (tapical thread)/British standard BSP (parallel/tapical thread)
Special custom threads: Supports non-standard thread processing
Classified by structure
Straight-through joints, three-way/four-way joints, elbow joints, reducer joints
Threaded joints with lock nuts and welded type
Core Advantages
high sealing performance
With the dual guarantee of precision thread processing and sealant/gasket, it has passed the ISO 9001 sealing test.
durable material
Carbon steel (surface galvanized/chrome-plated for anti-corrosion)
Stainless steel (304/316L, acid and alkali resistant, high temperature resistant)
Brass (anti-oxidation, suitable for drinking water systems)


flexible adaptation
Supports interchangeability of different diameters (DN6-DN150) and thread standards, and provides adapter solutions.
Easy to install
Threaded Pipe Coupling can be manually tightened without professional tools, reducing construction costs.
