Oetiker 16700083-100 Ear Clamp 3-3/8 in Stainless Steel

Product Description

The OETIKER 16700083-100 is a single-ear hose clamp designed for permanent, tamper-resistant hose and tubing connections. The clamp cinches down when the ear is crimped with a pincer tool, creating a uniform 360-degree seal around the hose. With a 3-3/8 inch nominal size, 7 mm band width, and 0.6 mm band thickness, this clamp suits a range of fluid-handling and pneumatic assemblies. The stainless steel construction resists corrosion in wet, chemical-exposed, and outdoor service environments. HVAC technicians, plumbers, and mechanical contractors rely on ear clamps where a permanent, vibration-resistant connection is required and reusability is not a concern.

This clamp is well suited for securing hoses, sleeves, and flexible connectors in residential and light commercial applications. Common install scenarios include condensate drain tubing, coolant hose connections, pneumatic line fittings, and flexible duct sleeve terminations. The single-ear design is favored when a low-profile, smooth-band clamp is needed to clear tight clearances or to meet OEM-style assembly standards. It is compatible with hose and tubing assemblies where a 3-3/8 inch nominal clamp diameter is specified.

Key Features

• Single-ear design creates a permanent, uniform seal when crimped with a standard pincer tool
• 3-3/8 inch nominal size fits a range of hose and tubing outside diameters
• 7 mm band width distributes clamping force evenly across the hose surface
• 0.6 mm band thickness provides consistent crimp performance without distortion
• Stainless steel construction resists corrosion in wet and chemically exposed environments
• Low-profile smooth band clears tight clearances in production and field assemblies

Compatibility

Designed as an OEM-style permanent ear clamp for hose and tubing assemblies requiring a 3-3/8 inch nominal clamp diameter across HVAC, plumbing, and mechanical applications.

Installation Notes

Installation requires a dedicated ear clamp pincer or crimping tool rated for single-ear clamps. Seat the clamp fully over the hose before crimping to ensure the band is positioned within the manufacturer-recommended distance from the hose end. Once crimped, the ear clamp is non-removable and non-reusable. Always depressurize or drain the line and follow applicable codes before servicing any hose or tubing connection.
