High Pressure 3000 PSI Stainless Steel Tee
This high pressure stainless steel tee is forged and machined to withstand working pressures up to 3000 PSI (Class 3000) in demanding fluid power and process systems. Produced from solid SS316 and SS316L bar stock using closed-die forging, the tee delivers dense, uniform grain structure and superior strength compared to cast alternatives.
Threaded and socket weld configurations are available to ANSI/ASME B16.11 and MSS SP-114 dimensions, with tapered NPT threads precision cut for a reliable, leak-tight seal. Each high pressure tee is pressure tested and supplied with full material traceability for critical oil and gas, hydraulic and instrumentation applications.

FAQ
Q: What does 3000 PSI mean for this stainless steel tee?
A: It indicates the fitting is rated for Class 3000 service, meaning it can withstand a working pressure of 3000 PSI at ambient temperature, per ASME B16.11 pressure-temperature ratings.
Q: Should I choose threaded or socket weld connection?
A: Threaded NPT connections allow quick assembly and disassembly, while socket weld provides a stronger, permanent joint better suited to vibration and high-cycle service.
Q: Is the tee made from bar stock or casting?
A: The tee is closed-die forged from solid SS316/SS316L bar, which yields a dense grain structure and superior mechanical strength versus cast fittings.
Manufacturing & Quality Control
Each high pressure tee is closed-die forged from certified SS316 and SS316L bar stock, then precision machined and threaded. Forging refines the grain structure and eliminates porosity, giving the fitting the strength needed for sustained 3000 PSI service. After machining, every tee is hydrostatically tested and dimensionally inspected to guarantee a leak-tight, reliable connection.
- Closed-die forging for dense, uniform grain structure.
- Precision cut NPT threads for a vibration resistant seal.
- 100% hydrostatic pressure testing before shipment.
- Full material certification for traceable critical service.
More Questions
Q: Is this tee suitable for sour gas or corrosive media?
A: For sour service or aggressive media, we recommend SS316L with proper NACE MR0175 qualification, or upgrading to duplex and super duplex grades for superior chloride resistance.
We stock a wide range of high pressure stainless steel tees in threaded and socket weld configurations for immediate dispatch, and can manufacture custom sizes and special materials such as duplex 2205 on short lead times for project requirements.
