Stainless Steel Male Tee
Product Details
Zhejiang Leadtek Fluid Technology Co., Ltd. is one of the most experienced manufacturers and suppliers of stainless steel male tee in China. Please feel free to buy customized stainless steel male tee at competitive price from our factory. Also, free sample is available.
Product Introduction
Stainless steel male tee is a T-shaped threaded pipe fitting with external (male) threads on all three ports - one run-through axis and one branch outlet - allowing direct connection to female-threaded pipes, valves, or equipment without additional adapters. Leadtek manufactures this fitting to ISO 4144 in SS304 and SS316, covering nominal sizes from 1/4" to 2" (DN8 to DN50).
The all-male thread configuration makes this fitting the preferred choice wherever a branch line must tie into a main run at a straight junction and connect directly to internally threaded components. It is widely used in food processing, chemical handling, water treatment, and industrial plumbing systems where corrosion resistance and leak-free performance are non-negotiable.
Product Features
All-External Thread Configuration
All three ports carry male threads, enabling direct connection to female-threaded valves, unions, or pipe ends. This eliminates the need for intermediate adapters and simplifies assembly in tight piping layouts.
ISO 4144 Dimensional Compliance
Manufactured to ISO 4144 standards, ensuring dimensional interchangeability with fittings from other compliant suppliers. Thread options cover NPT (ANSI/ASME B1.20.1), BSPT/BSPP (BS21), and metric equivalents per customer market requirements.
SS304 and SS316 Material Options
Standard production runs in SS304 for general industrial and construction applications. SS316 (with 2–3% molybdenum content) is available for chloride-rich environments, marine service, or chemical media requiring enhanced pitting resistance. SS304L and SS316L low-carbon variants are also available on request.
Rated for Working Pressures up to 2 MPa
At ambient temperature (–20°C to 40°C), these fittings carry a non-shock maximum working pressure of 2 MPa, derated to 1.35 MPa at 220°C. Suitable for steam, air, water, oil, and non-flammable gas service (Class 150).

OEM & Customization
Leadtek accepts OEM and custom orders for stainless steel male tees outside standard ISO 4144 configurations. Custom scope includes non-standard reducing port combinations, special thread forms (e.g., left-hand threads, straight-to-taper transitions), surface finishes (electropolished, passivated, or PED-compliant), and private-label marking. Minimum order quantities apply for non-standard runs; tooling costs are assessed on a project basis. Submit a drawing or specification sheet through the inquiry form and our technical team will respond within one business day.
