Oetiker 16700026-100 Ear Clamp 7/8 Inch Stainless Steel

Product Description

The OETIKER 16700026-100 is a single-ear clamp designed for permanent, low-profile hose and tubing connections in plumbing, HVAC, and fluid-handling applications. The clamp cinches down with a dedicated ear-closing tool, creating a tamper-evident, vibration-resistant joint. Constructed from stainless steel, it resists corrosion in wet and chemical-exposure environments. The band measures 7 millimeters wide and 0.6 millimeters thick, with a nominal hose size of 7/8 inch and an inner ear width of 10 millimeters. Plumbers, HVAC technicians, and mechanical contractors use this clamp type wherever a reliable one-time crimp connection is required.

This ear clamp is suited for residential and light commercial installations involving flexible hose connections on PEX tubing, refrigerant-line insulation jackets, low-pressure fluid lines, and similar applications. The single-ear design keeps a minimal footprint in tight spaces, making it a practical choice during rough-in work or equipment changeouts where clearance is limited. Installers should order in multiples of 10 to meet the minimum order quantity requirement.

Key Features

• Single-ear design creates a permanent, tamper-evident crimp connection
• Stainless steel construction provides corrosion resistance in wet environments
• 7 mm band width and 0.6 mm band thickness for consistent clamping force
• 10 mm inner ear width accommodates standard ear-closing pincer tools
• Nominal hose size of 7/8 inch suits common flexible tubing diameters

Compatibility

Designed as an OEM-style single-ear clamp for flexible hose and tubing connections at a nominal size of 7/8 inch, compatible with standard ear-closing installation tools.

Installation Notes

Installation requires a dedicated ear-closing pincer or clamp tool — do not attempt to close the ear with pliers or general-purpose crimpers, as uneven closure can compromise the seal. Shut off fluid supply and depressurize the line before fitting the clamp. Ensure the hose is fully seated on the fitting barb before crimping. This clamp is a single-use fastener and cannot be reopened or reused once closed.
