When you need hydraulic or pneumatic components in Chennai, choosing the right supplier is critical. A wrong purchase can lead to machine failure, downtime, and repeat costs.
Chennai offers many buying options, from local dealers to authorized distributors and OEMs. But not all sellers provide genuine parts, fast delivery, or proper support.
This guide explains where to buy, how to verify parts, delivery timelines, and includes a practical RFQ template for B2B buyers.
WHAT YOU NEED TO KNOW BEFORE BUYING
Components Checklist: What You Need Before You Shop
Before visiting a dealer or placing an order, you must know exactly what you need. Clear specifications help avoid wrong parts, delays, and disputes.
Below is a simple checklist of common hydraulic and pneumatic components.
Hoses and Hose Assemblies
Hoses carry fluid under pressure. They come in different sizes measured in dash numbers like -4, -6, -8, -12, and -16.
You need to know:
- Dash size (inner diameter)
- Pressure rating (maximum working pressure)
- Length required
- Type of end connections (SAE flange, NPT thread, JIC fitting)
- Hose material (rubber, polyurethane, or PTFE for high heat)
Common problems:
Hoses crack, leak, or burst when they are old, over-pressurized, or used in the wrong conditions.
Fittings and Adapters
Fittings connect hoses to machines and components. Common types include:
- Straight fittings
- 45-degree elbows
- 90-degree elbows
- Tees
- Unions
- Reducers
Always ask the dealer:
Do these fittings match my hose size, pressure rating, and thread type?
Hydraulic and Pneumatic Cylinders
Cylinders create pushing or pulling force. You must confirm:
- Bore size (piston diameter)
- Rod diameter
- Stroke length
- Mounting type (flange, trunnion, clevis)
- Pressure rating
- Surface coating (for corrosive or wet environments)
Incorrect cylinder specifications cause weak performance or seal failure.
Control Valves
Valves control fluid direction, speed, and pressure.
Common types:
- Directional control valves
- Pressure relief valves
- Flow control valves
- Check valves
Always verify that the valve pressure rating matches your system.
FRL Units (Filters, Regulators, Lubricators)
FRL units prepare compressed air for pneumatic systems.
- Filter removes dust and moisture
- Regulator controls pressure
- Lubricator adds oil to protect moving parts
For factories, check that the FRL unit supports your required airflow (CFM).
Pumps and Motors
Pumps move fluid. Motors convert fluid pressure into rotation.
You must know:
- Pump or motor type (gear, vane, piston)
- Flow rate
- Operating pressure
- Speed (RPM)
- Required power
Wrong pump selection leads to overheating and system damage.
