Sierra 18-9132-9 91329 Oetiker Clamp 9/16", 10/bag

Secure your marine hoses with confidence using these premium stainless steel Oetiker-style clamps. Designed for the demanding marine environment, the Sierra 18-9132-9 clamps deliver a tamper-proof seal that withstands vibration, corrosion, and constant exposure to saltwater and fuel. Each clamp fits 9/16-inch hoses perfectly, ensuring a uniform 360-degree compression that eliminates leaks and boosts reliability on the water.

Why These SS Clamps Stand Out in Marine Applications

Unlike traditional worm-gear clamps that can cut into hoses or loosen over time, these ear-style clamps provide a superior hold. Crafted from high-grade 300-series stainless steel, they resist rust even in harsh coastal conditions. The precision engineering means no tools required for basic installs beyond a proper crimping tool, and once set, they stay put through rough seas and engine vibrations.

• Exact Fit for 9/16" Hoses: Ideal for fuel lines, coolant hoses, and exhaust connections on outboard motors and inboards.
• Vibration-Resistant Design: The interlocking ears create a strong, consistent seal that won't slip under power.
• Corrosion-Proof Build: Full stainless steel construction battles electrolysis and chemical exposure.
• Pack of 10: Perfect for multiple repairs or routine maintenance without running short.

Real-World Performance on the Water

Boat owners swear by these clamps for everything from bilge pump lines to throttle cables. Imagine pushing your engine hard offshore—without the worry of a loose connection causing downtime. Their low-profile design keeps hoses tidy in tight engine bays, and the smooth inner band prevents hose damage over years of use. If you're tackling a winterization project or pre-season tune-up, these are the go-to for pros who demand leak-free performance.

Installation Tips for Long-Lasting Results

Getting the perfect crimp is straightforward. Slide the clamp onto the hose, position it away from fittings, and use an Oetiker-specific tool to squeeze the ears until they touch. Check the alignment by ensuring the band ends overlap smoothly. For best results, work in a dry area and avoid over-crimping, which could deform the steel. These clamps are reusable if removed carefully, saving time on adjustments.

1. Measure your hose diameter to confirm 9/16-inch compatibility.
2. Position clamp 1/4-inch from the hose barb.
3. Crimp firmly but evenly.
4. Inspect post-install for a tight, even seal.

Maintenance and Longevity Insights

Regular checks keep these clamps performing season after season. Wipe down after flushing the system to remove salt residue, and replace if ears show wear from extreme abuse. In high-heat areas like exhausts, pair with heat-resistant hoses for optimal durability. Their lightweight yet robust nature makes them a staple for DIY mechanics and seasoned mariners alike.
