OURU 20PCS 1/4" Fuel Line Clamp

OURU 20-piece adjustable fuel line clamps are 1/4" (11–13mm) stainless-steel hose clips designed for reliable, leak-resistant fastening of fuel, water, and air hoses.

These compact hose clamps from OURU give you a portable kit of 20 corrosion-resistant fasteners sized to grip 1/4" (7/16"–1/2") fuel lines and similar hoses. Built from 304 stainless steel and supplied with matching screws and nuts, the clamps are made to resist rust and oxidation for outdoor, marine, and workshop use. Their smooth, burr-free straps are engineered to tighten without cutting or deforming the hose, and the 360° sealing design minimizes leaks when clamped correctly.

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

The OURU clamps use a full-wrap strap and adjustable screw to compress the hose evenly around the fitting, producing a tight 360° seal. Even tightening pressure reduces gaps that cause drips or air ingress. Use a screwdriver to set the clamp until the hose is snug but not pinched.

• 360° sealing construction for continuous hose contact
• Smooth strap edges to avoid cutting or nicking hose material
• Adjustable screw gives controlled compression for leak prevention

What sizes and materials should I expect in this 20-piece kit?

This pack contains twenty identical clamps, each sized to fit hoses with an outer diameter from 7/16" to 1/2" (11–13mm). All components — straps, screws, and nuts — are made of 304 stainless steel for durable corrosion resistance. The consistent machining helps ensure uniform fit across multiple fittings.

• Fits 7/16"–1/2" (11–13mm) hose diameters
• 20 clamps per kit for spares and multiple installations
• 304 stainless steel screws, nuts, and straps for rust resistance

Where are these clamps best used and how easy are they to install?

OURU mini hose clamps are suitable for fuel lines, silicone hoses, air hoses, water pipes, and small-diameter plumbing or marine applications. Installation requires only a standard screwdriver; place the clamp over the hose and fitting, then turn the screw until you achieve a secure seal. The compact size works well in tight or confined spaces common on vehicles and small machinery.

• Suitable for automotive fuel lines, marine hoses, and home plumbing repairs
• Easy installation with a flathead or Phillips screwdriver
• Compact design fits cramped engine bays and tight hose runs

Will these clamps damage hoses or fail under tension?

OURU clamps are engineered with sturdy steel straps and rounded edges to prevent cutting into hose material during tightening. The construction resists deformation and stripping, so clamps hold tension without breaking. For critical high-pressure systems, select clamps rated for the application and inspect regularly.

• Rounded, burr-free strap edges reduce abrasion and slicing risk
• Durable steel strap resists breakage during tightening
• Recommended for general-purpose and medium-pressure use—check specifications for extreme pressures

Who is this for: The OURU 20PCS 1/4" Fuel Line Clamp set is ideal for mechanics, marine technicians, DIY homeowners, and hobbyists who need a reliable supply of small, corrosion-resistant hose clamps for maintenance and repairs. If you work on small engines, boats, garden equipment, or household plumbing and require consistent, leak-resistant connections for 11–13mm hoses, this kit delivers a practical, long-lasting solution.
