Oetiker 15100012-100 2-ear Clamp 7/8 Inch

Product Description

The OETIKER 15100012-100 is a 2-ear clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from stainless steel, it delivers corrosion resistance in wet or chemically active environments. The clamp features a 9 mm band width with 1 mm thickness, providing consistent clamping force across the full seating area. A nominal size of 7/8 inch covers a clamping range of 19.10 mm to 23.00 mm, making it suited for standard small-bore hose connections. Installation requires a pincer or ear-clamp tool to properly crimp and lock the ears. This type of clamp is a standard fastening component used by plumbers, HVAC technicians, and mechanical contractors.

The OETIKER 15100012-100 is used in residential and light commercial installations wherever a low-profile, single-use crimp clamp is required. Common applications include PEX tubing fittings, coolant hose connections, refrigerant-side accessory lines, and pneumatic tubing assemblies. The 7/8 inch nominal size targets small-diameter hose ends commonly found in hydronic systems, fluid transfer lines, and compressed-air connections. Its stainless steel construction handles both indoor and outdoor exposure without degradation.

Key Features

• 2-ear crimp design provides permanent, vibration-resistant hose retention
• Stainless steel construction resists corrosion in wet and chemically active service environments
• 9 mm band width distributes clamping load evenly across the hose bead
• 1 mm band thickness maintains structural integrity under sustained pressure
• Clamping range of 19.10 mm to 23.00 mm suits standard 7/8 inch nominal hose ends
• Low-profile ear design allows installation in confined spaces

Compatibility

Designed as an OEM-style replacement or new-installation crimp clamp for 7/8 inch nominal small-bore hose and tubing connections in plumbing, HVAC, and fluid-handling assemblies.

Installation Notes

Installation requires a calibrated ear-clamp pincer tool sized for 2-ear Oetiker-style clamps. Depressurize and drain the line before removing any existing clamp or fitting. Once crimped, 2-ear clamps are single-use and cannot be reopened or repositioned. Confirm the hose is fully seated on the fitting barb before crimping to ensure a leak-free connection.
