Our Extended Press-fit Brass Pipe Fittings utilize an integrated composite structure, featuring a standard external thread at one end and a standard press-fit port at the other. A single fitting enables the direct connection of metal piping to threaded components, eliminating the need for intermediate adapters and simplifying piping layouts.
Precision-machined from forged brass, these fittings offer high mechanical strength and excellent resistance to oxidation and scale corrosion. The dual-sealing structure—combining threaded and press-fit connections—provides robust leak protection, ensuring reliability under standard hot/cold water supply and heating conditions.

The external threaded section and the press-fit port are forged as a single unit. With no welded joints or seams, the fitting offers superior structural integrity, preventing cracking or loosening caused by long-term water pressure surges or pipeline vibrations.
One side features a standard external thread for connecting to valves, manifolds, or threaded equipment ports; the other side features a standardized press-fit end compatible with copper and stainless steel pipes, eliminating the need for additional reducers or conversion adapters.
The streamlined dimensions minimize space usage in pipe shafts and ceiling voids, making them suitable for concealed residential piping and densely arranged commercial HVAC installations.
These fittings are manufactured from premium forged brass, offering high material density and mechanical rigidity. They resist deformation under pressure, ensuring reliable performance during long-term, high-pressure pipeline operation.
The inner and outer walls undergo precision turning, resulting in a smooth surface that resists scale buildup. The brass material is oxidation-resistant and withstands corrosion from the medium, ensuring durability against long-term exposure to cold/hot water supplies and heating fluids without rusting.
Compatible with residential cold water, domestic hot water, and high-temperature heating water circulation systems. It offers stable pressure resistance suitable for standard HVAC and plumbing systems, ensuring broad operational applicability.
The external threads are precision-cut with uniform profiles, ensuring a tight fit with mating female-threaded components; combined with a sealing gasket, this effectively blocks leakage through the thread gaps.
The press-fit end features a high-performance elastic seal. Upon compression with a press tool, the pipe and fitting lock tightly together; the seal adapts to thermal expansion and contraction, preventing joint leakage.
The combination of threaded and press-fit seals provides a double layer of leak prevention. This maintains a stable seal even amidst frequent water pressure fluctuations, thereby reducing the frequency of future maintenance and repairs.
By dispensing with traditional welding, the process requires no hot work on-site. This eliminates the risk of sparks igniting nearby insulation or decorative materials, allowing for safe installation in enclosed ceiling spaces and finished interiors.
Pipe crimping requires only a universal press tool, eliminating the need for multi-person teams for welding or applying thread seal tape. Assembly at each point is quick, effectively lowering labor costs for large-scale projects.
With integrated sealing structures, there is no need to purchase auxiliary items like thread seal tape or sealant during installation, thereby reducing the variety of materials to procure and easing inventory management.
Standard single-crimp or single-threaded fittings cannot directly connect piping to threaded equipment; they require additional adapters. This product features an integrated dual-interface design, enabling direct connection between the two types of components. This reduces the total number of joints in the pipeline, thereby minimizing potential leak points.
Traditional assembly methods involving multiple fittings consume more space, making installation difficult in cramped ceiling voids or densely packed pipe shafts. This single-piece fitting provides dual-interface connectivity, resulting in a cleaner, more organized pipeline layout.
Standard projects typically require stocking both crimp couplings and male/female threaded adapters. Purchasing this single composite fitting meets all connection needs between piping and threaded components, reducing inventory variety and capital tied up in stock.
Pipelines assembled from multiple fittings have numerous joints; long-term use carries the risk that a leak at any single joint necessitates disassembly and repair. With fewer joints and fewer potential failure points, this product significantly reduces the workload for future maintenance, modifications, and disassembly.
Suitable for domestic cold and hot water lines. It connects water pipes to threaded interfaces on water heaters, manifolds, and angle valves. It is free from heavy metal leaching, making it ideal for concealed residential piping.
Suitable for heating and cooling circulation lines in shopping malls and office buildings. It connects heating pipes to threaded interfaces on manifolds and thermostatic valves. Its temperature and pressure resistance make it suitable for high-frequency, year-round operation.
Suitable for factory lines transporting ambient-temperature fresh water or circulating fluids. It connects metal piping to threaded industrial valves and offers corrosion resistance capable of withstanding standard industrial fluid media.
Material composition is verified before brass raw materials are accepted into storage. Substandard materials are rejected, ensuring stable base material performance right from the source.
Each Extended Press-fit Brass Pipe Fitting undergoes sequential testing for connection integrity, airtightness/hydrostatic leak detection, and thread dimension/tolerance verification; non-conforming products are sorted out and discarded, ensuring they do not reach the shipping stage.
Raw material inspection records and finished product test reports are systematically archived, enabling full-process quality traceability from raw material to final shipment for every batch.
We provide—upon request—brass material composition certificates, airtightness and pressure-bearing test reports, factory certificates of conformity, and official certificates of origin, meeting requirements for both domestic engineering acceptance inspections and overseas customs clearance.
We offer free technical guidance on piping selection, press-fitting tool operation protocols, and pipeline layout planning, helping to preemptively avoid leaks caused by incorrect selection or improper installation.
We guarantee stable, long-term supply for bulk engineering procurement clients; our after-sales team responds rapidly to any malfunctions or inquiries during installation and use, providing practical, effective solutions.
A: It is compatible with standard copper pipes and thin-walled stainless steel pipes available on the market; it can be used directly for both new installations and the retrofitting of existing pipelines.
A: The product features a dual-sealing structure (combining threaded and press-fit connections) and undergoes rigorous factory testing for airtightness and hydrostatic pressure; it adapts to thermal expansion/contraction and frequent pressure fluctuations, making leaks unlikely when installed according to specifications.
A: We provide a complete documentation package, including material certificates, airtightness and pressure-bearing test reports, factory certificates of conformity, and certificates of origin, ensuring compliance with customs clearance requirements and local acceptance standards for fire protection and HVAC projects.
A: Traditional solutions require two separate fittings—a press-fit coupling to connect to the pipe and a separate male-threaded adapter to connect to threaded equipment. This approach demands two pressing operations and one threaded assembly, involving multiple components, more threaded joints, and increased sealing points—each a potential leak risk. On-site assembly is time-consuming, and the inventory must stock two different part numbers. This integrated fitting combines both functions into a single component. It requires only one pressing operation to complete the connection from pipe to threaded equipment—cutting installation time by approximately 50% per joint. With fewer components and fewer threaded connections, the risk of leakage is significantly reduced. For bulk projects, this translates into measurable labor savings, simplified procurement, and lower long-term maintenance costs associated with multiple threaded joints.
