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 convenient solution for pipeline conversion, equipment installation, extension, repair, and maintenance.
The fitting body is manufactured using lost-wax investment casting technology and finished through precision CNC machining. This manufacturing process helps provide consistent dimensions, accurate thread profiles, good mechanical strength, and dependable connection performance.
Available in SS201, SS304, SS316, and SS316L, the fittings can be selected according to the transported medium, operating temperature, corrosion conditions, installation environment, and project requirements.

The threaded connection allows the fitting to be installed without extensive on-site welding. This can simplify pipeline assembly, reduce installation time, and make future maintenance or replacement more convenient.
Correct identification of the thread standard is essential. NPT, BSPT, BSP, DIN 2999, and ISO 228 threads may use different thread profiles, taper angles, dimensions, and sealing methods. They should not be connected interchangeably unless their compatibility has been technically confirmed.
Suitable thread sealant, sealing tape, gasket, or sealing compound should be selected according to the thread type, working pressure, temperature, and transported medium.
Available sealing materials include PTFE, silicone rubber, and FKM fluororubber. Each material provides different levels of temperature resistance, chemical compatibility, flexibility, and sealing performance.
The appropriate gasket material should be selected according to:
Transported medium
Working pressure
Operating temperature
Chemical concentration
Hygiene requirements
Required service life
Installation environment
For fuel gas, chemical, food, medical, and high-temperature applications, the compatibility of the gasket and stainless steel material should be confirmed before ordering.
LIANHE stainless steel female-to-male threaded fittings can be used in 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, operating temperature, transported medium, stainless steel grade, thread standard, gasket material, and installation conditions.
For medical, food, fuel-gas, chemical, or other regulated applications, customers should confirm whether additional testing, surface treatment, certification, or quality documentation is required.
OEM and ODM orders are accepted. We can also manufacture customized stainless steel threaded fittings according to customer drawings, samples, technical specifications, and special application requirements.
Available customization options include:
Product dimensions
Female and male thread combinations
Stainless steel material grades
Thread directions and specifications
Gasket and sealing 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 standards when requesting customized products.
Each fitting is protected with a plastic bag to reduce exposure to moisture, dust, and surface contamination. Products are then packed in reinforced export cartons and consolidated in wooden cases when required.
This standard export packaging method helps protect the fittings from impact, scratches, contamination, and handling damage during storage and international transportation.
Customized cartons, customer logos, barcodes, labels, pallet packing, and other packaging arrangements can be supplied according to 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.
Available payment methods include:
T/T bank transfer
Western Union
L/C
PayPal
Other mutually agreed payment methods
Available Trade Terms: EXW, FOB, CFR, CIF, DDP, and DDU
