Oetiker 16702047 Ear Clamp 1-3/16 in Stainless Steel

Product Description

The OETIKER 16702047 is a single-ear clamp designed for secure, permanent hose and tube connections in HVAC, plumbing, and fluid-handling applications. The clamp is formed from stainless steel and features a nominal size of 1-3/16 inches, a band width of 7 millimeters, and a band thickness of 0.6 millimeters. The ear measures 10 millimeters in inner width. Once crimped with the appropriate pincer tool, the ear deforms uniformly around the hose, creating a leak-free, vibration-resistant seal that cannot be loosened without cutting. Licensed trades and assembly technicians install these clamps where reusability is not required and a tamper-evident, low-profile connection is preferred.

Ear clamps in this size range are used in residential and light commercial HVAC systems, hydronic heating lines, refrigerant-side tubing assemblies, and potable-water plumbing connections where flexible hose meets a barbed or spigot fitting. The 1-3/16-inch nominal size suits common hose diameters found on condensate drain lines, coolant hoses, and similar small-bore flexible tubing. This clamp is appropriate wherever a smooth outer profile is required to clear tight clearances or insulation wrap.

Key Features

• Nominal size of 1-3/16 inches for small-bore hose and tubing connections
• Stainless steel construction resists corrosion in wet or chemically active environments
• 7 millimeter band width provides even clamping force distribution across the hose bead
• 0.6 millimeter band thickness delivers consistent crimp performance without splitting
• 10 millimeter inner ear width accepts standard ear-clamp pincer tooling
• Single-use, permanent crimp design eliminates loosening from vibration or thermal cycling

Compatibility

Designed as an OEM-style replacement or new-installation ear clamp for flexible hoses and tubing with a nominal diameter of 1-3/16 inches in HVAC, plumbing, and fluid-handling assemblies.

Installation Notes

Installation requires a dedicated ear-clamp pincer or crimping tool matched to the ear width — standard pliers are not an acceptable substitute. Before installing, shut off fluid flow and relieve any system pressure. Position the clamp over the hose bead and apply the crimping tool squarely across the ear to ensure a uniform, leak-free deformation. Once crimped, the clamp is permanent and must be cut off for hose removal.
