Products Description
304 Introduction
Grade 304 stainless steel (UNS S30400, EN 1.4301, GB 06Cr19Ni10), commonly known as 18/8 stainless steel, is a widely used chromium‑nickel austenitic stainless steel and the base grade of the 300 series. It contains 18.0–20.0% chromium, 8.0–10.5% nickel and a maximum of 0.08% carbon, with iron as the balance. Chromium forms a self‑healing passive oxide film for corrosion resistance, while nickel stabilizes the austenitic structure and improves ductility, toughness and low‑temperature performance. In the annealed condition, it has a density of 7.93 g/cm³, minimum yield strength of 205 MPa, tensile strength of 520–750 MPa and elongation over 40%. It cannot be hardened by heat treatment; strength increases only by cold working, which may cause slight magnetism, a normal characteristic. It resists corrosion in air, fresh water, weak acids and alkalis and is easy to clean for sanitary use, but it is susceptible to pitting corrosion in chloride‑rich environments. When held at 425–850 ℃, it becomes sensitized and prone to intergranular corrosion. Solution annealing at 1010–1120 ℃ followed by rapid cooling restores its corrosion resistance. It has good formability and weldability yet relatively poor machinability.
This material is widely used in food equipment, kitchenware, pharmaceutical vessels, architectural decoration, heat exchangers, fasteners and cryogenic components, and is not recommended for service in seawater or strong reducing acids.
304 Ferrule-type Tee Fitting Introduction
304 Ferrule-type Tee Fitting is a three-way compression tube fitting made of 304 stainless steel. It adopts double ferrule sealing structure, which can form reliable tight connection with seamless tubing by tightening the nut. The tee design enables one inlet to split into two outlets or two inlets to converge into one outlet for fluid distribution in instrument piping systems. 304 stainless steel provides excellent corrosion resistance, good mechanical strength and stable performance for a wide temperature range. It features easy installation, no welding required, and convenient disassembly and re-assembly. This fitting is widely used in hydraulic, pneumatic, gas and liquid instrumentation pipelines, suitable for petrochemical, power, laboratory and industrial automation systems. Multiple tube size options are available to meet different pipeline layout requirements.

304 Ferrule-type Tee Fitting Product Processing
1.Raw Material Inspection:
We use 304 stainless steel solid bar as raw material. Each batch receives strict incoming inspection, including spectral composition test, hardness and mechanical property test, surface visual inspection for cracks, inclusions, scratches and pits, and dimensional verification of the steel bar. Any unqualified stock is isolated and returned to supplier. Only qualified 304 stainless steel bars can enter the production process.
2.CNC Turning Machining:
3.Separated Parts Machining:
4.Deburring & Precision Cleaning:
5.Pre-assembly & Performance Spot Check:
6.Final Inspection & Packaging:
2.CNC Turning Machining:
The steel bar is fixed on precision CNC lathe. The machine processes the three-way main body, including inner flow channel, ferrule sealing cone surface, thread section and outer contour. Strictly control the coaxiality of three ports, the angle of the sealing cone, thread pitch and tolerance, inner hole roughness and flow channel smoothness, to avoid burrs, taper deviation and dimensional out-of-tolerance which will affect sealing performance.
3.Separated Parts Machining:
Process supporting nuts and ferrules separately. Nuts are turned to form internal thread and pressing end face; ferrules are machined to get front cutting edge, rear conical surface and inner hole. Every key sealing surface is finished with fine turning to guarantee matching precision with the tee body.
4.Deburring & Precision Cleaning:
Remove burrs on flow channel, thread, cone sealing surface and ferrule cutting edge by manual trimming and ultrasonic vibration tumbling. Then all components are sent to ultrasonic cleaning tank to remove cutting oil, metal chips and dust inside holes and threads. After cleaning, use dry filtered compressed air to fully dry all parts, no residual oil, water or debris left, which is critical for high-pressure sealing.
5.Pre-assembly & Performance Spot Check:
Carry out trial assembly of tee body, ferrules and nuts to verify thread fit, ferrule compression action and contact fit of sealing cone. Random sampling for hydraulic pressure test to check leakage under rated working pressure. Parts with thread jamming, poor fit or pressure leakage are rejected.
6.Final Inspection & Packaging:
Full sampling inspection for overall dimension, thread quality, surface finish, sealing cone condition and marking. Qualified fittings are sorted and packed into anti-scratch plastic bags, then packed into export cartons. Each carton is labeled with material grade, specification, batch number, quantity and inspection mark for storage and shipment.
