Oetiker 10100041-100 2-ear Clamp 1-5/16 in Carbon Steel

Product Description

The OETIKER 10100041-100 is a 2-ear stepless clamp used to secure hoses, boots, and flexible lines in plumbing, automotive, and HVAC applications. The clamp features a 10.00 mm band width and 1.50 mm band thickness, providing consistent clamping force when ears are crimped with the correct pincer tool. Constructed from carbon steel with a zinc-plated finish for corrosion resistance, this clamp delivers a low-profile, permanent connection without the bulk of worm-gear or T-bolt hardware. It is installed by licensed plumbers, HVAC technicians, and mechanical contractors who require a reliable, tamper-resistant hose termination.

This clamp is suited for residential and light commercial installations where a 1-5/16 inch nominal size hose or tubing connection is required. Typical applications include condensate drain lines, coolant hoses, radiant heating tubing connections, and flexible duct boot attachments. The clamping range of 29.30 mm to 34.00 mm accommodates standard hose ODs within that band. It is commonly used wherever a one-time, stepless crimp clamp is preferred over a reusable screw-type clamp.

Key Features

• 2-ear stepless design provides even 360-degree clamping pressure when crimped
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 10.00 mm band width and 1.50 mm thickness for robust clamping force
• Clamping range of 29.30 mm to 34.00 mm suits standard 1-5/16 inch nominal hose ODs
• Low-profile ear profile fits in tight spaces where larger clamp hardware will not
• Permanent crimp installation reduces the risk of loosening over time

Compatibility

Designed as an OEM-style replacement or new-installation 2-ear clamp for hose and tubing connections with a nominal size of 1-5/16 inches and an OD falling within the 29.30 mm to 34.00 mm clamping range.

Installation Notes

Installation requires a dedicated ear-clamp pincer or stepless clamp tool — standard pliers are not an appropriate substitute and will not produce a reliable crimp. Power down or depressurize the system before servicing any hose or line connection. Once crimped, the clamp is permanent and must be cut away for removal; reuse is not recommended. Follow applicable IPC or IFGC guidelines for the specific piping system being serviced.
