Oetiker 15100016-100 2-ear Clamp 1-1/8 Inch

Product Description

The OETIKER 15100016-100 is a 2-ear clamp designed for permanent, vibration-resistant connections on hose and tubing assemblies. The clamp is manufactured from stainless steel with a 10 mm band width and 1 mm band thickness. Once crimped with the appropriate pincer tool, the ears deform and lock the clamp at a fixed diameter, creating a leak-free seal that cannot be loosened without cutting the clamp. This style of clamp is widely used by HVAC technicians, plumbers, and automotive or industrial service professionals where a tamper-evident, single-use fastening method is required.

This clamp fits applications where the hose or tubing outer diameter falls within the clamping range of 26.30 mm to 31.00 mm (approximately 1.035 inches to 1.220 inches). Typical uses include coolant hose connections, condensate drain lines, low-pressure fluid transfer lines, and PEX or corrugated tubing terminations in residential and light commercial plumbing and HVAC systems. The stainless steel construction resists corrosion in wet or chemically active environments.

Key Features

• 2-ear design provides a permanent, tamper-evident crimp connection
• Stainless steel construction resists corrosion in wet and chemical environments
• 10 mm band width distributes clamping force evenly across the hose bead
• 1 mm band thickness provides consistent ear deformation during crimping
• Clamping range of 26.30 mm to 31.00 mm suits common 1-1/8 inch nominal hose sizes
• Ear inner width of 7.38 mm (0.256 inches) is compatible with standard OETIKER-style pincer tooling

Compatibility

Designed as an OEM-style replacement or service clamp for hose and tubing assemblies requiring a 1-1/8 inch nominal 2-ear crimp clamp with a clamping range of 26.30 mm to 31.00 mm.

Installation Notes

Installation requires a dedicated ear-clamp crimping tool (pincer or pincers-style); standard worm-drive or spring-clamp pliers will not correctly deform the ears. Ensure the hose is fully seated over the fitting barb before crimping. This clamp is a single-use fastener and must be cut off for removal — do not attempt to re-open a crimped clamp. Follow applicable plumbing or HVAC codes for the system being serviced.
