LIANHE stainless steel female-to-male threaded fittings are designed to connect pipes, valves, instruments, and other pipeline components with different threaded-end configurations. The female and male threaded structure provides a practical solution for pipeline conversion, extension, equipment installation, and maintenance.
The fitting body is manufactured using lost-wax investment casting technology and finished by precision CNC machining. This manufacturing process helps provide consistent dimensions, accurate thread profiles, stable mechanical strength, and dependable connection performance.
Available in SS201, SS304, SS316, and SS316L, the fittings can be selected according to the operating environment, transported medium, corrosion conditions, temperature, and project requirements.

The threaded connection allows installation without extensive on-site welding. This can simplify pipeline assembly, shorten installation time, and make future inspection, maintenance, or replacement more convenient.
Correct identification of the thread standard is essential. NPT, BSPT, BSP, DIN 2999, and ISO 228 threads may have different profiles, taper angles, and sealing methods. They should not be connected interchangeably unless their dimensional and sealing compatibility has been technically confirmed.
Available sealing materials include PTFE, silicone rubber, and FKM fluororubber. Each gasket material provides different temperature resistance, chemical compatibility, flexibility, and sealing performance.
The appropriate gasket should be selected according to:
Transported medium
Working pressure
Operating temperature
Chemical concentration
Hygiene requirements
Expected service life
Installation environment
For fuel gas, chemicals, food, medical, and high-temperature applications, gasket compatibility should be confirmed before placing an order.
LIANHE stainless steel female-to-male threaded fittings are suitable for a wide range of industrial and commercial pipeline systems, including:
Construction and building-service pipelines
Fuel-gas systems using compatible materials and seals
Medical equipment and facility piping
Food and beverage processing equipment
Environmental protection systems
Chemical-processing equipment
Water-treatment facilities
Industrial water pipelines
Machinery and instrument connections
General fluid-control systems
The final product configuration should be selected according to the working pressure, temperature, transported medium, stainless steel grade, thread standard, gasket material, and installation conditions.
Additional testing, surface treatment, certificates, or quality documents may be required for medical, food, fuel-gas, chemical, or other regulated applications.
OEM and ODM orders are accepted. Stainless steel threaded fittings can also be manufactured according to customer drawings, samples, technical specifications, and special project requirements.
Available customization options include:
Product dimensions and wall thickness
Female and male thread combinations
Stainless steel material grades
Gasket materials
Surface-treatment requirements
Customer logos and product markings
Inspection and testing requirements
Labels and export packaging
Customers should provide complete drawings, dimensions, materials, operating conditions, quantities, and inspection requirements when requesting customized products.
Each fitting is protected with a plastic bag to help prevent moisture, dust, and surface contamination. Products are then packed in reinforced export cartons and consolidated in wooden cases when required.
Customized cartons, customer logos, barcodes, labels, pallet packing, and other packaging arrangements can be provided according to the confirmed order requirements.
Our standard payment term is a 30% T/T deposit paid in advance, with the remaining 70% T/T balance paid before delivery. Specific payment arrangements can be discussed according to the order value and cooperation conditions.
