OURU 20PCS 3/8" Fuel Line Clamp

OURU 20PCS 3/8" Fuel Line Clamp kit is a set of adjustable 304 stainless-steel hose clamps sized to fit 9/16"–5/8" (14–16mm) hoses for fuel, water, air and silicone lines.

This compact kit gives mechanics, DIYers and fleet operators a ready supply of corrosion-resistant mini hose clamps designed to stop leaks and hold hoses securely under pressure. Each clamp features a screw-adjust mechanism and a smooth, burr-free steel strap to protect hoses from cuts while delivering a 360° sealing surface. The clamps come with matching screws and nuts so each piece is ready to install straight from the box.

How do these clamps prevent fuel or fluid leaks?

The OURU clamps use a full-wrap (360°) band that compresses evenly around the hose when the screw is tightened, minimizing gaps and pressure points that cause leaks. The smooth inner edge prevents damage to hose material, so the seal stays reliable even after repeated tightening.

• 360° sealing design for even compression
• Screw-adjust mechanism for precise clamping force
• Smooth, burr-free strap to protect hose surfaces
• Suitable for fuel, water, air and silicone lines

What sizes and materials are included, and will they fit my hoses?

Each clamp is sized to adjust between 9/16" and 5/8" (14–16mm), making them ideal for 3/8" nominal fuel lines and similar-diameter hoses. The clamps are stamped from 304 stainless steel, which resists rust and oxidation, extending service life for outdoor or marine use.

• Adjustable range: 9/16"–5/8" (14–16mm)
• Material: 304 stainless steel with included screws and nuts
• Pack count: 20 pieces for spares and multi-point installs
• Fits fuel, diesel, coolant, water and air lines of matching diameter

How easy are these clamps to install and re-use?

Installation requires only a standard screwdriver or nut driver to turn the included screw and tighten the band. The screw-and-nut design allows the clamp to be adjusted, removed and reinstalled without deforming the band, so clamps can be reused when servicing hoses.

• Install with screwdriver or nut driver
• Re-tensionable for maintenance or hose replacement
• Sturdy strap resists breakage during tightening
• Compact size useful in tight engine compartments

Where are these clamps commonly used and what environments do they suit?

These mini high-pressure hose clamps are used across automotive, marine, agricultural and home plumbing tasks. Their stainless construction and compact footprint make them suitable for outdoor exposure and corrosive environments like saltwater or road-salt conditions.

• Automotive fuel and vacuum lines
• Marine and boating hoses exposed to salt air
• Home plumbing, irrigation and small appliance lines
• Agricultural equipment and light industrial piping

Who is this for? The OURU 20PCS 3/8" Fuel Line Clamp kit is aimed at professional mechanics, backyard mechanics, boat owners and maintenance teams who need a reliable, corrosion-resistant clamp that fits 14–16mm hoses. If you service fuel, coolant, or air systems and want a compact, reusable clamp that reduces hose damage and leaks, this kit provides 20 ready-to-use clamps to cover routine repairs and spare-part stocking. The packaging is convenient for mobile toolboxes and workshop bins, offering a practical balance of durability, size range and quantity for frequent use.
