Types of fitting?

1. Pipe fittings: used to connect pipes and tubing in plumbing and HVAC systems
2. Electrical fittings: used to connect electrical wires and cables in electrical systems
3. Hydraulic fittings: used to connect hydraulic hoses and tubes in hydraulic systems
4. Pneumatic fittings: used to connect pneumatic hoses and tubes in pneumatic systems
5. Compression fittings: used to connect pipes or tubing by compressing a ring or ferrule onto the pipe
6. Flare fittings: used to connect pipes or tubing by flaring the end of the pipe and using a nut and sleeve to secure the connection
7. Quick-connect fittings: used for easy and quick connections without the need for tools
8. Union fittings: used to connect two pipes or tubing sections together in a straight line
9. Elbow fittings: used to connect pipes or tubing at a 90-degree angle
10. Tee fittings: used to connect three pipes or tubing sections together in a T-shape configuration.

Types of Fittings

Pipe Fittings

- Elbows: Connect pipes at angles (90°, 45°, etc.)
- Tees: Form three-way connections
- Reducers: Change pipe diameters
- Crosses: Connect four pipes
- Caps: Close off pipe ends
- Couplings: Join two pipes straight

Hose Fittings

- Barb fittings: Connect hoses with barbs
- Compression fittings: Crimp onto hoses using ferrules
- Push-to-connect fittings: Push hoses into fittings without tools
- Quick-disconnect fittings: Allow hoses to be quickly connected and disconnected
- Hydraulic fittings: Withstand high pressures

Threaded Fittings

- Male fittings: Have external threads
- Female fittings: Have internal threads
- NPT (National Pipe Thread): Standard thread for pipes
- BSP (British Standard Pipe): Standard thread used in Europe
- Flare fittings: Provide a flared connection for a secure seal

Compression Fittings

- Sleeve fittings: Use a sleeve to compress a ferrule onto a pipe
- Ring fittings: Use a compression ring to create a seal
- Push-in fittings: Push pipes into fittings to create a connection

Welding Fittings

- Buttweld fittings: Joined by buttwelding
- Socket weld fittings: Welded into sockets
- Slip-on fittings: Slide over pipes and are welded in place
- Flange fittings: Connect with flanges that are bolted together

Other Fittings

- Valves: Control fluid flow
- Gauges: Measure pressure, temperature, or flow
- Expansion joints: Compensate for thermal expansion
- Isolation joints: Isolate vibrations and noise
- Flexible hoses: Connect components with flexibility
