Tube fittings are essential components used to connect, control, and direct the flow of fluids in
high-pressure and industrial piping systems. High-quality fittings ensure leak-free performance, corrosion
resistance, and long-term durability in demanding applications.
Here are some common types of Tube Fittings:
- Union Tee & Female Tee:
- Branch Tee & Run Tee:
- Male / Female Connector:
- Elbow:
- Bulkhead Union:
- Reducing Union:
- OD Cap / Plug:
- Manifold:
Used for branching and connecting tubes at 90° angles with robust sealing for high-pressure lines.
Designed to split or extend tube runs while maintaining consistent flow and pressure.
Provides secure tube-to-threaded connections in hydraulic and instrumentation systems.
Enables directional change of flow, typically 45° or 90°, without compromising sealing integrity.
Allows tube connections through panels or walls ensuring leak-free joint separation.
Connects tubes of different sizes while maintaining pressure performance and sealing.
Used to close or seal unused tube ends in fluid systems.
Enables distribution or combining of multiple tube lines in a compact configuration.
These tube fittings are available in Stainless Steel, Duplex Steel, Alloy Steel, Carbon Steel, Copper Alloys, Nickel Alloys, Monel, Inconel, and Hastelloy to suit different pressures and environmental conditions.
