DELPHI FITTINGS
Part Number: 1603
NPSM Pipe Swivel Female Tee
Product Overview
The Delphi Fittings Part 1603 is an NPSM (National Pipe Straight Mechanical) Pipe Swivel Female Tee. This versatile steel fitting is designed to connect three male NPT (National Pipe Taper) or NPTF (Dryseal) threaded fittings or pipes in a T-configuration. A key feature of this tee is that all three connections are female NPSM pipe swivel nuts. This triple-swivel design offers maximum flexibility during installation, allowing each of the three connected lines or components to be independently oriented and tightened without imparting any torsional stress on the others or the tee body itself. Manufactured from high-quality carbon steel and typically zinc-plated for corrosion resistance, the Part 1603 tee provides a robust and highly adaptable solution for creating complex branched connections in hydraulic and pneumatic systems where ease of assembly and precise alignment are critical.
Key Features & Specifications
| Material | High-Grade Carbon Steel |
|---|---|
| End 1 Configuration (Run) | Female NPSM Pipe Swivel (National Pipe Straight Mechanical) (threads conforming to ANSI/ASME B1.20.1) |
| End 2 Configuration (Run) | Female NPSM Pipe Swivel (National Pipe Straight Mechanical) (threads conforming to ANSI/ASME B1.20.1) |
| End 3 Configuration (Branch) | Female NPSM Pipe Swivel (National Pipe Straight Mechanical) (threads conforming to ANSI/ASME B1.20.1) |
| Body Style | Tee Adapter, typically with a forged body for strength and flats for wrench engagement. |
| Sealing Mechanism | All NPSM Female Swivel Ends: NPSM threads are straight and do not provide a seal on the threads themselves. Sealing is achieved when these connect to male NPT/NPTF fittings (seal on male tapered threads, requiring sealant) or specific male NPSM fittings designed with a sealing seat. The swivel nuts facilitate tightening without rotating the tee body. |
| Corrosion Protection | Standard Zinc Plating for enhanced durability and resistance to environmental corrosion. |
| Primary Function | To provide a T-junction connecting three male NPT or NPTF threaded fittings or pipes, with the convenience of swivel action on all three ends for maximum installation flexibility and precise orientation. |
| Working Pressure | Suitable for a range of hydraulic and pneumatic systems. Specific pressure ratings are dependent on the size of the tee, the application conditions, and the integrity of the seals on the mating male NPT/NPTF threads. |
Commonly Available Sizes (Part #1603 Series)
Delphi Fittings offers the Part 1603 NPSM Pipe Swivel Female Tee in various common nominal pipe sizes. All three female NPSM swivel ends are typically of the same size.
Examples include (Female NPSM Swivel x Female NPSM Swivel x Female NPSM Swivel):
- 1603-02: 1/8" NPSM Female Swivel on all three ends (for 1/8" Male NPT/NPTF)
- 1603-04: 1/4" NPSM Female Swivel on all three ends (for 1/4" Male NPT/NPTF)
- 1603-06: 3/8" NPSM Female Swivel on all three ends (for 3/8" Male NPT/NPTF)
- 1603-08: 1/2" NPSM Female Swivel on all three ends (for 1/2" Male NPT/NPTF)
- 1603-12: 3/4" NPSM Female Swivel on all three ends (for 3/4" Male NPT/NPTF)
- 1603-16: 1" NPSM Female Swivel on all three ends (for 1" Male NPT/NPTF)
Note: This tee is designed to connect to male NPT or NPTF fittings, which will provide the sealing surface. For unlisted size combinations, specific material requirements (e.g., stainless steel options), or other custom needs, please contact our sales team.
Applications
The Part 1603 NPSM Pipe Swivel Female Tee is exceptionally useful for:
- Creating a T-junction by connecting three male NPT or NPTF threaded pipes or fittings, especially where the orientation of all three connected lines is critical and independent adjustment is needed.
- Installations in hydraulic or pneumatic systems with complex routing or tight spaces where the triple swivel action greatly simplifies assembly and prevents stress on hoses or components.
- Applications requiring a manifold-like connection point with high adaptability for alignment.
- Various industrial piping systems where flexibility in connecting pressure gauges, sensors, or auxiliary lines is beneficial.
Installation & Usage Guidelines
- Ensure all mating male NPT/NPTF threads and the female NPSM swivel threads of the tee are meticulously clean, undamaged, and free from any contaminants.
- Apply a suitable thread sealant (such as PTFE tape or a compatible pipe dope) to all three male NPT or NPTF threads of the fittings/pipes that will be connected to the tee. Ensure sealant is applied correctly, avoiding the first one or two threads.
- Thread each male fitting into the respective female NPSM swivel ends of the tee by hand until snug.
- The swivel action on all three ends allows the tee body and the other connected components to be held stationary while each swivel nut is tightened independently. This facilitates precise orientation of each connected line.
- Use appropriate wrenches to tighten each swivel nut to achieve a secure, leak-proof seal on the tapered threads of the mating male NPT/NPTF fittings. The amount of tightening will depend on the size and materials.
- Always use appropriate backup wrenches on the tee's body (if hexed or with flats) and the mating components during tightening to prevent over-torquing or damage.
