Description
Overview:
The O Clip Zinc Plated 9mm-11mm Double Ear Hose Clamp Fastener is a compact, one-piece clamp designed to create a tight, reliable seal on small-diameter hoses. Made from zinc-plated steel for added corrosion resistance, it provides firm, even compression around the hose to help prevent leaks of liquids, gases, and air. The 9 mm to 11 mm size range (approximately 0.35 inches to 0.43 inches) suits many small fuel, air, and coolant lines found on construction equipment, garden machinery, pressure washers, generators, and compressors. The double ear design is crimped with suitable pincers, giving a low-profile, tamper-resistant fit that performs well under vibration. Rounded edges reduce the risk of hose damage, making it a dependable choice for maintenance and repair tasks.
Key Features:
- Zinc-plated steel construction for durability and corrosion resistance
- Double ear design for strong, uniform clamping force and a secure seal
- Fits hose outer diameters from 9 mm to 11 mm (0.35 inches to 0.43 inches)
- Low-profile form for tight or confined installations
- Rounded edges to help protect hose surfaces and reduce wear
- Suitable for sealing liquids, gases, and air in low to medium pressure systems
- Crimp-to-fit (single-use) design helps prevent loosening from vibration
- Quick installation using standard ear clamp pincers
- Reliable choice for small engines, pumps, compressors, and general machinery
- Works with many common hose materials when sized correctly
Typical Applications:
Used on small engine fuel lines, breather and vacuum hoses, pneumatic lines, washer and coolant bypass hoses, irrigation and sprayer tubing, and general-purpose fluid transfer lines. Common in garden machinery, construction tools, workshop equipment, generators, compressors, and pressure washers where a compact, secure, and corrosion-resistant clamp is required.
Also known as:
Often referred to as an O-clip, ear-type clamp, crimp-on clamp, pinch clamp, double-ear clamp, Oetiker-style ear clamp, or band-type crimp clamp. These names describe the same crimp-to-tighten, low-profile fastening method used to achieve a reliable, permanent seal on small-diameter hoses.
