OURU Fuel Line Clamp Assortment Kit 120PCS, 8 Sizes 7–18mm (9/32"–23/32") — 304 Stainless, Screw-Tight 360° Seal

OURU 120PCS Fuel Line Clamp Assortment is a stainless-steel kit of 8 precision sizes (7–18mm) designed to create leak-resistant seals on fuel, coolant and vacuum hoses for automotive, marine and DIY repairs.

This compact, organized kit supplies 120 corrosion-resistant mini hose clamps—each stamped with inch markings—so you can match the correct diameter quickly and tighten with a screwdriver for a secure fit. Crafted from 304 stainless steel and designed with smooth edges and a 360° sealing band, the clamps are built to resist rust, avoid hose damage and minimize deforming under pressure. Packaged in a robust storage box, the assortment helps pros and hobbyists keep fasteners sorted and on hand for maintenance, repair, or fabrication tasks.

How do these clamps prevent leaks on fuel and coolant lines?

The clamps use a continuous 360° band and a finely threaded screw to distribute clamping force evenly around the hose, reducing high-pressure points that cause seepage. Their stainless-steel construction also resists corrosion that can compromise seals over time.

• Continuous band design for uniform compression
• Built-in inch markings to match clamp to hose diameter
• 304 stainless steel resists rust and oxidation
• Screw-tightened adjustment for repeatable torque

Which hose sizes are included and how is the kit organized?

The assortment covers eight commonly used inner diameters from 7mm up to 18mm (9/32" to 23/32"), allowing you to service small fuel lines, vacuum hoses, and coolant pipes. The clamps are separated inside a sturdy box so you can grab the right size without rummaging.

• Eight sizes spanning 7–18mm (9/32"–23/32") to fit varied hose diameters
• 120 pieces total—ample quantity for multiple projects or spares
• Compact, durable storage case for easy transport and organization
• Each clamp marked in inches for quick selection

Are these clamps durable and safe for repeated use?

Yes; the 304 stainless steel construction and burr-free finished edges reduce the risk of strap breakage and minimize cutting into hose material. The clamps are designed for repeated tightening and loosening without strip-out or deformation when used within their size range.

• Sturdy steel straps resist fracture during tightening
• Smooth, deburred edges prevent hose abrasion
• Screw and nut hardware included and corrosion-resistant
• Suitable for reuse when not overstressed beyond recommended torque

Where can I use these mini hose clamps around vehicles and the home?

These clamps are versatile for automotive fuel and vacuum lines, marine fittings, agricultural equipment, and household plumbing or appliance connections. They’re sized for smaller-diameter hoses where larger worm gear clamps are impractical.

• Fuel lines, vacuum hoses, coolant return lines, silicone connectors
• Marine and boating hose assemblies where corrosion resistance matters
• Small home plumbing, irrigation, and appliance hose repairs
• Industrial or workshop uses requiring compact, high-pressure clamps

Who is this for: The OURU 120PCS Fuel Line Clamp Assortment is ideal for mechanics, boat owners, farmers, maintenance technicians and DIYers who need a ready supply of reliable, compact hose clamps in multiple sizes. If you frequently service small-diameter hoses or want an organized kit that resists rust and reduces hose damage, this collection offers a practical, cost-effective solution to keep fittings tight and leaks minimized.
