In fluid handling systems, tubing and fittings play crucial roles. However, they serve different purposes:
-
Tubing refers to the flexible or rigid hollow structure used to transport fluids or gases from one point to another. It is available in different materials such as stainless steel, PVC, PTFE, and more.
-
Fittings are connectors or joints used to link tubing sections together or to connect tubes with valves, pumps, or tanks. Common types include elbows, tees, reducers, unions, and adaptors.
Whether you're setting up a pneumatic system, chemical transfer line, or process instrumentation, choosing the right tubing and fitting combination ensures leak-proof, efficient, and safe operations.
Applications
Tubing and fittings are widely used across various industries. Below is a balanced list of common applications:
Tubing Applications:
- Fluid transfer in process automation
- Compressed air systems
- Laboratory gas lines
- Food and beverage production
- Chemical dosing and sampling
Fitting Applications:
- Connecting instrumentation in control panels
- Pneumatic and hydraulic lines
- Vacuum systems
- Water treatment connections
- Oil & gas piping systems
FAQ – Frequently Asked Questions
Can I reuse fittings after removing them from tubing?
Some push-to-connect or compression fittings are reusable, but it’s best to follow the manufacturer’s guidelines.
How do I know which fitting size matches my tubing?
Always check the outer diameter (OD) or inner diameter (ID) of the tubing and match it with the fitting size specification.
What materials are recommended for chemical applications?
For aggressive chemicals, PTFE tubing with 316L stainless steel or PVDF fittings are preferred.
Are tubing and hoses the same?
Not exactly. Tubing generally refers to rigid or semi-rigid fluid paths, while hoses are more flexible and often reinforced for pressure.
