Oetiker 10500342-100 1-ear Clamp 1-13/16 Inch

Product Description

The OETIKER 10500342-100 is a 1-ear stepless clamp designed for secure, permanent hose and tube connections in plumbing, HVAC, and fluid-handling applications. The single-ear design is compressed with a pincer tool to create a uniform 360-degree grip around the hose or fitting. Constructed from carbon steel with a zinc-plated head coating, this clamp resists corrosion in typical service environments. The band measures 7 mm wide and 0.75 mm thick, providing consistent clamping force across the full clamping range of 27 mm to 30.10 mm. The 1-13/16 inch nominal size suits a wide range of standard hose and tubing outside diameters in residential and light commercial systems.

This clamp is used wherever a tamper-evident, non-adjustable connection is required. Common applications include PEX tubing connections, coolant hoses, automotive and HVAC refrigerant-side assemblies, and low-pressure fluid lines. The 1-ear configuration is the industry-standard choice when installers need a low-profile clamp that does not require re-torquing after installation. This part is sold individually but must be ordered in multiples of 10 units per the minimum order quantity requirement.

Key Features

• Single-ear stepless design provides permanent, uniform 360-degree clamping force
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7 mm band width and 0.75 mm band thickness for consistent grip and low-profile fit
• Clamping range of 27 mm to 30.10 mm suits 1-13/16 inch nominal hose and tubing OD
• Ear inner width of 0.394 inches (10 mm) compatible with standard OETIKER pincer tooling
• No re-torquing required after installation — tamper-evident permanent connection

Compatibility

Designed as an OEM-style replacement or new-installation clamp for hoses and tubes with an outside diameter within the 27 mm to 30.10 mm clamping range, consistent with 1-13/16 inch nominal sizing used in plumbing, HVAC, and fluid-line assemblies.

Installation Notes

Installation requires a dedicated OETIKER ear-clamp pincer or equivalent single-ear crimping tool — do not attempt to close the ear with pliers, as uneven compression will compromise the seal. Shut off fluid flow and depressurize the line before installation. Ensure the hose is fully seated on the fitting barb before positioning and compressing the clamp ear. Installers should verify local plumbing and mechanical codes for approved connection methods when using ear clamps on potable water or pressure-bearing lines.
