O-Clip Single-Ear Hose Clamp — 11–13mm (53-1803)
Part No: 53-1803 | Barcode: 19484 | Range: Air Fittings & Piping
The 53-1803 is a single-ear O-type hose clip that gives a permanent 360-degree seal on small-bore hose across a 11–13mm range. You crimp the ear closed with O-clip pincers to draw the band evenly around the hose, leaving a low-profile, vibration-proof joint where a bulky worm-drive clamp won’t fit.

Key Features & Benefits
- 11–13mm clamping range — sized for small-bore hose where a worm-drive clamp is too large.
- 360-degree even seal — the continuous band squeezes uniformly around the hose, with no screw housing to leave a gap or pressure point.
- Crimp-on ear — close the ear with O-clip pincers for a fast, permanent fitting that won’t back off under vibration.
- Low profile — the slim band suits tight clearances and tidy looms on air, fuel and coolant lines.
When to Use This Clamp
Reach for part 53-1803 for a permanent seal on small-bore hose in the 11–13mm band — air, fuel, vacuum or coolant lines, especially in tight spaces where a worm-drive clamp is too bulky. Use proper O-clip crimping pincers so the ear closes squarely and the band tensions evenly. These clips are single-use — cut and replace when you remove the hose.
