Oetiker 16700031-100 Ear Clamp 1 Inch Stainless Steel

Product Description

The OETIKER 16700031-100 is a single-ear hose clamp designed for secure, permanent connections on hose assemblies in HVAC, plumbing, and fluid-handling applications. The clamp is formed from stainless steel and uses a one-time mechanical crimping method to create a consistent, leak-resistant seal. With a nominal size of 1 inch, a band width of 7 millimeters, and a band thickness of 0.6 millimeters, this clamp is sized for standard hose connections where vibration-resistant, tamper-evident fastening is required. Installation is performed with ear clamp pliers or a dedicated pincer tool. Technicians in plumbing, HVAC, and industrial service work use these clamps where reusable worm-drive clamps are not acceptable.

This ear clamp is suited for residential and light commercial applications where hose-to-barb or hose-to-fitting connections require a permanent, low-profile crimp. Common install scenarios include PEX tubing connections, condensate drain lines, coolant hoses, and other fluid-carrying assemblies that demand a factory-style finish. The 10-millimeter inner ear width provides consistent deformation during crimping for a reliable seal across the full hose circumference.

Key Features

• Single-ear design creates a permanent, tamper-evident crimp connection
• Stainless steel construction resists corrosion in wet and humid environments
• 7 millimeter band width distributes clamping force evenly across the hose
• 0.6 millimeter band thickness provides strength while maintaining a compact profile
• 10 millimeter inner ear width for consistent tool engagement and deformation
• 1 inch nominal size fits standard hose and tubing barb fittings

Compatibility

Designed as an OEM-style single-ear clamp for 1 inch nominal hose and tubing connections in plumbing, HVAC condensate, and fluid-handling assemblies.

Installation Notes

Installation requires ear clamp pliers or an OETIKER-style pincer tool to crimp the ear to the closed position. Power down or depressurize the system before fitting or inspecting clamps on pressurized lines. Single-ear clamps are a one-time-use fastener and must be cut off with side cutters for removal. Follow applicable codes such as IPC or IFGC for hose connection requirements in plumbing and gas applications.
