OURU 20PCS 5/16" Fuel Line Clamp

Compact, corrosion-resistant hose clamps from OURU: 20 adjustable 5/16" fuel line clips that secure hoses sized 1/2"–9/16" (13–15mm) with a 360° leak-reducing seal.

These OURU mini fuel line clamps are made for mechanics, DIYers and marine or agricultural users who need small, reliable hose fasteners. Each kit includes 20 clamps crafted from 304 stainless steel with screws and nuts, offering long-term rust resistance and consistent sizing for common fuel, air and water lines. The clamps tighten with a standard screwdriver, delivering a smooth, burr-free band that won’t cut into hoses and helps prevent leaks under moderate pressure.

How do these clamps prevent hose leaks?

The OURU clamps use a continuous band design that compresses evenly around the hose, reducing gaps where fluids or air could escape. A full 360° contact area avoids point pressure that can deform soft hoses, and the precision screw allows gradual tightening to the optimal tension.

• 360° sealing construction for uniform compression
• Adjustable screw lets you fine-tune clamp tension
• Smooth, burr-free band prevents hose damage
• Fits common 13–15mm (1/2"–9/16") hose diameters

Will these clamps resist corrosion outdoors or in marine use?

Yes — the clamps are stamped from 304 stainless steel, a widely used grade for durability and oxidation resistance. That material choice helps them hold up to wet, salty or humid environments better than standard plated clamps.

• 304 stainless construction for long-term rust resistance
• Includes stainless screws and nuts to avoid galvanic mismatch
• Suitable for marine, automotive, and outdoor equipment

Are these clamps easy to install and adjustable for different hoses?

Installation is straightforward: position the band, then tighten the screw with a screwdriver until the hose is secure. The size range is designed to cover small fuel and vacuum lines common in engines, appliances, and workshop fittings, making them versatile for repairs and maintenance.

• Simple screwdriver tightening; no special tools required
• Adjustable range: 1/2"–9/16" (13–15mm) for snug fits
• Sturdy steel strap prevents breakage during installation

What applications and hoses are these clamps best suited for?

These clamps are intended for small-diameter hoses where a compact, low-profile clamp is needed. They perform well on fuel, silicone, air, and water lines in automotive, agricultural, plumbing, and hobbyist contexts.

• Automotive fuel and vacuum lines (diesel and petrol systems)
• Small water or air hoses in home and workshop projects
• Marine fittings and outdoor equipment maintenance
• Industrial or agricultural lines requiring corrosion resistance

Who is this for? The OURU 20PCS 5/16" Fuel Line Clamp kit is tailored for anyone needing multiple compact, reliable hose clamps: home mechanics, boat owners, maintenance technicians, builders, and hobbyists. If you work with small-diameter hoses and value stainless durability, leak-conscious sealing, and easy screwdriver installation, this set offers a practical, cost-effective solution for routine repairs and preventative maintenance.
