Your salon chair is likely leaking oil because of issues within its hydraulic system, specifically cracked hoses or faulty seals.
Salon chairs often use a hydraulic system to allow for easy height adjustment. This system relies on a special oil (hydraulic fluid) contained within a closed circuit. When you pump the foot lever, pressure is built, pushing the fluid and lifting the chair. When you release a valve, the fluid pressure decreases, lowering the chair.
Causes of Leaking Hydraulic Fluid
As highlighted in the document "Hydraulic Fluid Leakage," a primary reason for malfunctions in hydraulic systems, including those in salon chairs, is a leak. The most common culprits behind these leaks are:
-
Cracked Hoses: The flexible hoses that carry the hydraulic fluid can become brittle or damaged over time due to age, wear and tear, or physical stress. A crack in a hose allows the pressurized fluid to escape.
-
Faulty Seals: Seals (like O-rings or gaskets) are used at various connection points, such as where hoses connect to cylinders or pumps. These seals are designed to prevent fluid from leaking out. However, they can degrade, dry out, crack, or become displaced, creating gaps through which oil can leak.

How Leaks Affect Performance:
- Loss of Pressure: As fluid leaks out, the total volume of fluid in the system decreases. This makes it difficult or impossible for the pump to build sufficient pressure.
- Inability to Hold Height: With reduced pressure, the chair may slowly sink even after being pumped up, as the system cannot maintain the required force against gravity.
- Visible Puddles: The most obvious sign is the presence of oily residue or puddles underneath or around the chair base.
What to Look For
If your salon chair is leaking, inspect the following areas:
- The base of the chair, especially near the pump mechanism.
- Any visible hoses running from the pump to the cylinder.
- The cylinder itself (the part that goes up and down).
- Connection points where hoses attach.
Even a small leak can worsen over time, leading to significant performance issues and potentially making the chair unusable.
Addressing the Issue
Identifying the exact source of the leak is the first step. Since it often involves internal components like seals or pressurized hoses, fixing a hydraulic leak typically requires professional repair or replacement of the damaged parts. Attempting repairs without proper knowledge can be dangerous or cause further damage.
Replacing a leaking chair or seeking professional repair ensures the hydraulic system can once again hold pressure effectively, allowing the chair to function safely and reliably at the desired height.
