OPERATING PRINCIPLE
How Male Threaded Tee Works
1. **Equal-Diameter Threaded Tee Design**: Features three externally threaded ports of the same nominal diameter, forming a 90° branch for fluid distribution or convergence.
-
2. **Precision-Cast Construction**
Robust wall thickness with a dense, high-quality metallurgical structure—free from porosity or sand inclusions—ensuring stable and reliable pressure-bearing performance.
-
3. **AISI 304 Stainless Steel**
Offers excellent rust and corrosion resistance; suitable for use with fresh water, mildly corrosive media, and outdoor installations.
-
4. **Precision-Machined External Threads**
Available in NPT, BSPT, or BSPP thread specifications. Thread tolerances comply with ISO 7-1, DIN 2999, or ANSI B1.20.1 standards, ensuring a tight, leak-free assembly.
-
5. **150LB Pressure Rating**
Compliant with the ISO 4144 standard, suitable for general industrial piping systems.
-
6. **Pickled and Passivated Surface Finish**
Provides a uniform metal surface that further enhances corrosion resistance; supports custom marking on the fitting body.
-
7. **Comprehensive Size Range**
Available in sizes from 1/4″ to 2″ (DN8 to DN50), with support for OEM custom marking.

Frequently Asked Questions
Find answers to common questions about sizing, materials, threaded connections and operating conditions.
1、 What is a Male Threaded Tee?
Male Threaded Tee is a T-shaped pipe fitting with **external male threads on all three ports (M×M×M)**. It splits or combines fluid flow in a pipeline. All three male thread ends screw into female threaded ports of pipes, valves or other fittings.
> Note: Distinguish from common female threaded tee (F×F×F) and reducing tee.
2、What is the difference between Male Threaded Tee and standard Female Threaded Tee?
– Male Threaded Tee: **M×M×M**, three external threads, all ports screw into female connectors.
– Female Threaded Tee: **F×F×F**, three internal threads, male pipe ends screw into the tee.
> We also supply reducing male threaded tee (3 ports with different male thread sizes) upon request.
4、 What materials can you supply?
– Stainless steel 304 / 316L (corrosion resistant, water, gas, chemical)
5、What materials can you supply?
– Stainless steel 304 / 316L (chemical, seawater, corrosive media)
6、What applications?
Water supply, compressed air, natural gas, fire protection, HVAC, instrument piping, oil, low & medium pressure industrial pipeline, plumbing systems.
7、Can you provide MTC material certificate?
Yes, EN10204 3.1 MTC with heat number is available. EN10204 3.2 third-party certificate can be arranged at buyer’s extra cost.
8、Surface finish options?
Standard: pickled matte finish.
9、Can you do laser marking?
Yes. We can mark size, grade, heat number, customer logo or brand on the flats.
10、Packaging for sea shipment?
Male threads are protected by plastic thread caps. Packed into export cartons, then loaded on fumigated wooden pallets with waterproof stretch film to avoid scratch and thread damage.
11、What is the lead time?
Typically, shipments are dispatched within 7–15 days of receiving the deposit, depending on the order quantity.
12、How is quality controlled?
Raw material inspection → CNC machining → Thread inspection → Hydrostatic testing → Visual inspection → Final dimensional verification before packaging.
13、Which Incoterms are available for overseas buyers?
We offer FOB (Free On Board) terms, with the shipment originating from a Chinese port. We will provide a commercial invoice, packing list, and bill of lading for import customs clearance.
14、Which Incoterms are available for buyers?
We offer FOB (Free On Board) or CIF (Cost, Insurance, and Freight) terms, with shipments originating from a Chinese port. We will provide a commercial invoice, packing list, and bill of lading for customs clearance.
15、What should be done if the threads are found to be defective or do not meet requirements upon arrival?
Please provide photos, videos, and inspection records. We will assess the root cause; depending on the contractual terms, solutions may include product replacement, a partial refund, or a reshipment.”
