Stainless Steel Double Ear O-Clips — Hose Clamps for Fuel, Air & Water Lines

Measure the outer diameter (OD) of your hose after it is pushed onto the barb or fitting — the hose expands slightly when fitted, and that is the dimension the clip must grip. The clip size range should bracket that measurement. For example, a hose OD of 8mm would typically use the 7–9mm clip. In imperial terms: 8mm ≈ 5/16". When in doubt, size down rather than up to ensure a secure, leak-free seal.

Double ear O-clips are generally rated for low-to-medium pressure hose connections typical of automotive fuel, coolant, and air lines. Exact burst pressure depends on the hose material and wall thickness as much as the clip itself. For high-pressure hydraulic lines, a different clamp style is typically required. If you have a specific pressure rating requirement, please contact us to confirm suitability.

Stainless steel O-clips generally perform well in damp, humid, and moderately corrosive environments — including under-hood automotive use and outdoor irrigation applications. For prolonged saltwater or highly acidic exposure, a 316-grade stainless clip is typically recommended. Please contact us to confirm the exact alloy grade if corrosion resistance is a critical requirement for your project.

Yes. Double ear O-clips are commonly used on fuel, oil, coolant, and air lines in automotive, small-engine, and marine applications. Always verify that the hose material itself is rated for the specific fluid being carried — the clip secures the connection, but the hose must be chemically compatible with the fluid.

You need an ear clamp pincer tool, also called an O-clip crimping tool or ear clamp pliers. Position the clip over the hose and fitting, place the tool jaws over the ears, and squeeze to crimp. The ears fold down and lock permanently — no screwdriver, no worm-drive, and no re-torquing needed. The crimping tool is not included with this listing.

Each listing offers packs of 10, 30, 50, or 100 clips of the same size range. If you need multiple sizes, simply select each size variant and add them to your cart separately. Buying in larger quantities (50 or 100 pcs) reduces the per-clip cost significantly for workshop or fleet maintenance use.

Double ear O-clips work with most flexible hose types including rubber, silicone, PVC, and reinforced braided hose. They are not intended for rigid pipe, push-fit fittings, or compression fittings. The hose must be flexible enough to compress slightly under the clip for a proper seal.
