Description
Description:
Compression sleeves, also known as olives or ferrules, are essential components in compression fittings, used to create a secure, leak-proof seal between tubing and compression nuts. These sleeves deform slightly when compressed to form a tight connection without the need for soldering or welding.
The size designation (e.g., 4/2, 12/9) typically refers to the outer diameter (OD) and inner diameter (ID) of the tubing the sleeve is designed for:
-
4/2 sleeve: 4 mm OD tube, 2 mm ID
-
12/9 sleeve: 12 mm OD tube, 9 mm ID
Key Features:
-
Material Options:
-
Brass (standard for many general-purpose applications)
-
Stainless steel (for high pressure or corrosive environments)
-
Plastic or nylon (for low-pressure, non-metallic systems)
-
-
High Leak Resistance:
Forms a tight mechanical seal suitable for gas and fluid systems. -
Reusable Fittings:
Can often be reused with new sleeves for maintenance or adjustments. -
No Welding or Soldering Required:
Simplifies installation and avoids heat-related damage to components. -
Wide Compatibility:
Suitable for use with copper, plastic, aluminum, and steel tubing depending on sleeve and fitting material. -
Applications Include:
-
Hydraulic and pneumatic systems
-
Instrumentation and control lines
-
Refrigeration and air conditioning
-
Water supply lines
-
Gas delivery systems
