LIANHE stainless steel female threaded fittings are manufactured for dependable connections in industrial, commercial, and general fluid-handling pipeline systems. The precision-machined female threads allow the fittings to connect with compatible male threaded pipes, valves, instruments, and equipment components.
The fitting body is manufactured using lost-wax investment casting technology and finished through precision CNC machining. This process helps produce consistent dimensions, accurate thread profiles, good mechanical strength, and stable connection performance.
Available materials include SS201, SS304, SS316, and SS316L. Customers can select a suitable stainless steel grade according to the transported medium, corrosion conditions, operating temperature, installation environment, and project requirements.

The female threaded connection allows the fitting to be installed without extensive on-site welding. This simplifies pipeline assembly and makes future inspection, maintenance, disassembly, or replacement more convenient.
Correct thread selection is essential for reliable installation. NPT, BSPT, BSP, DIN 2999, and ISO 228 threads may have different thread profiles, taper characteristics, and sealing methods. These thread standards should not be used interchangeably unless their dimensional and sealing compatibility has been technically confirmed.
Suitable thread sealant, sealing tape, gasket, or sealing compound should be selected according to the thread type, transported medium, working temperature, and pressure conditions.
Available gasket materials include PTFE, silicone rubber, and FKM fluororubber. Different sealing materials provide different levels of temperature resistance, chemical compatibility, flexibility, and long-term sealing performance.
The appropriate gasket material should be selected according to:
Transported medium
Operating temperature
Working pressure
Chemical concentration
Hygiene requirements
Required service life
Installation conditions
For fuel gas, chemicals, food, medical, and other specialized applications, customers should confirm the compatibility of the gasket and stainless steel material before placing an order.
LIANHE stainless steel female threaded fittings can be used in a range of industrial, commercial, and equipment piping applications, 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 fitting configuration should be selected according to the working pressure, operating temperature, transported medium, stainless steel grade, thread standard, gasket material, and installation environment.
Additional testing, surface treatment, certificates, or inspection documents may be required for medical, food, fuel-gas, chemical, and other regulated applications.
OEM and ODM orders are accepted. We can also manufacture customized stainless steel female threaded fittings according to customer drawings, samples, technical specifications, and special project requirements.
Available customization options include:
Product dimensions
Stainless steel material grades
Female thread types
Thread directions and combinations
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, material requirements, 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 products 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 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.
Available payment methods include:
T/T bank transfer
Western Union
L/C
PayPal
Other mutually agreed methods
Available Trade Terms: EXW, FOB, CFR, CIF, DDP, and DDU
Products can be delivered by sea freight, air freight, land transportation, or international express service.
The shipping method can be selected according to the order quantity, package volume, destination, required delivery time, and transportation budget.
For regular-size products, the minimum order quantity normally ranges from 1 to 20 pieces, depending on the product size, material, thread type, and current stock availability.
MOQ for Non-Standard Products: Normally 500 pieces
The minimum order quantity for customized products may vary according to the dimensions, material grade, casting requirements, machining complexity, tooling cost, and inspection scope.
Free Samples: Free samples may be provided for dimensional verification, material evaluation, and product testing. International express delivery charges are normally paid by the recipient.
