omprehensive Guide to Hydraulic & Pneumatic Fittings: Precision Brass Components for Fluid Power Systems

1. The Core Role of Fittings in Hydraulic and Pneumatic Systems

In modern machinery, fittings are the essential joints that connect every line of pressure and flow.
A high-quality fitting ensures system integrity, prevents leakage, and maintains efficiency even under extreme conditions.

Hydraulic and pneumatic fittings act as the safety gatekeepers of energy transmission.
Once a fitting fails, the system loses stability and reliability.

2. Working Principles

Hydraulic Systems

Hydraulics rely on the incompressibility of oil to transfer energy.

• Stable high pressure (up to 700 bar)

• Smooth transmission

• Minimal loss and vibration

Pneumatic Systems

Pneumatics use compressed air, which is clean, fast, and flexible.

• Lightweight operation

• Quick response

• Ideal for automation

Both systems rely on fittings to prevent leakage, withstand pressure, and allow efficient disassembly.
