Sierra 18-9135-9 1891359 Oetiker Clamp 13/16", 10/bag

Discover the Reliability of Stainless Steel Oetiker Clamps for Your Marine Needs

Secure your hoses with confidence using these precision-engineered stainless steel clamps. Designed for demanding environments like marine engines, these clamps provide a tamper-proof seal that withstands vibration, corrosion, and extreme temperatures. Whether you're maintaining an outboard motor, inboard engine, or plumbing system on your boat, these clamps deliver consistent performance where ordinary fasteners fail.

Unlike traditional worm-gear clamps that can loosen over time or damage hoses, these ear-style clamps use a unique crimping mechanism for a uniform 360-degree compression. This ensures no leaks, even under high pressure or pulsation from fuel lines, coolant hoses, or exhaust systems.

Key Features That Set These Clamps Apart

• Premium Stainless Steel Construction: Type 316L for superior resistance to saltwater, chemicals, and rust—ideal for harsh marine conditions.
• Precise 13/16-Inch Sizing: Perfect fit for common hose diameters in small to medium marine applications, reducing slippage and over-tightening risks.
• Convenient 10-Pack: Stock up efficiently for multiple repairs or routine maintenance without running short mid-job.
• Low-Profile Design: Minimizes bulk in tight engine compartments, preventing interference with belts, wires, or other components.
• Reusable with Proper Tools: Built tough to handle repeated installations when using the right side-cutter or crimp tool.

Performance in Real-World Scenarios

Boat owners rave about how these clamps hold up during long offshore trips or in brackish water. They outperform zinc-plated alternatives by resisting galvanic corrosion when paired with dissimilar metals, extending the life of your entire cooling system.

Ideal Applications Across Marine and Beyond

These clamps shine in high-vibration setups:

• Fuel and water lines on outboards like Mercury or Yamaha.
• Coolant hoses in sterndrive systems.
• Exhaust tubing and bilge pump connections.
• DIY hydraulic or pneumatic repairs in workshops.

Pro tip: Pair with high-quality silicone or nitrile hoses for the ultimate seal. In automotive circles, they're a go-to for turbocharger boost hoses or radiator lines where precision matters.

Step-by-Step Installation Guide for Flawless Results

1. Prep the Hose: Cut cleanly at a 90-degree angle and slide over the fitting until fully seated.
2. Position the Clamp: Align the clamp ear perpendicular to the hose flow, 1/8-inch from the hose barb end.
3. Crimp Securely: Use an Oetiker-specific tool to pinch the ear flat—aim for a slight overlap without deforming the hose.
4. Inspect: Tug-test the hose and check for gaps; recrimp if needed.
5. Clean Up: Trim any excess with diagonal cutters for a professional finish.

Common mistake to avoid: Over-crimping, which pinches hoses. These clamps require just enough force for a permanent bond—practice on scrap first.

Long-Term Maintenance and Troubleshooting Tips

Inspect clamps annually or after every 50 hours of operation. Look for ear deformation or hose swelling. In salty environments, rinse with fresh water post-use. If replacing, these clamps remove cleanly without hose damage, saving time and frustration.
