O Clips

Tanair Double-Ear O Clip Sizes

Measure the Hose After It Is on the Tail

The most important sizing point is that the clip does not simply match the hose bore. Once flexible hose is pushed over a hose tail, its outside diameter increases.

Measure the outside diameter of the completed hose-and-tail assembly and select a clip whose clamping range includes that measurement.

Why Use a Double-Ear O Clip?

The clip is positioned around the hose over the hose tail, then both ears are compressed using suitable O clip pincers or ear-clamp pliers.

• Compact, low-profile hose retention
• Two ears help distribute clamping force around the hose
• Useful for permanent workshop and pneumatic hose assemblies
• No protruding screw mechanism like a conventional worm-drive hose clip

Fitting an O Clip Correctly

• Choose the correct hose tail for the hose internal diameter
• Push the hose fully onto the hose tail before measuring
• Select an O clip with the correct clamping range
• Position the clip over the hose-tail section
• Crimp both ears evenly using suitable O clip pincers
• Inspect the assembly before safely repressurising the system

Replace O Clips After Removal

Double-ear O clips are normally treated as single-use components. Once the ears have been crimped, the clip should generally be cut off for removal and replaced with a new correctly sized clip rather than reused.

Choose the Retention Method to Suit the Job

O clips provide a compact crimped connection, while Jubilee-style worm-drive clips are adjustable and can be removed more easily. The best choice depends on the hose, pressure, access and application.

Whichever method is used, the hose, fitting and retaining clip must all be suitable for the operating conditions.
