Oetiker 15500029-100 1-ear Clamp 1-3/4 in Stainless

Product Description

The OETIKER 15500029-100 is a single-ear stepless clamp designed for permanent, vibration-resistant connections on hose and tubing assemblies. The one-ear design deforms plastically when crimped, creating a uniform 360-degree seal that does not loosen over time. Built from stainless steel with a band width of 7 mm and a wall thickness of 0.6 mm, this clamp is well suited for demanding environments where corrosion resistance and consistent clamping force are required. It is installed using a standard OETIKER ear-clamp pincer tool and is commonly specified in automotive, plumbing, HVAC, and fluid-handling assemblies by technicians who require a tamper-evident, non-adjustable fastening solution.

This clamp is appropriate for nominal 1-3/4 inch hose and tubing connections across a wide range of trade applications including refrigerant line insulation sleeves, coolant hoses, PEX-to-fitting transitions, and pneumatic tubing terminations. It is suitable for both residential and light commercial installations where a low-profile, single-use clamp is preferred over a worm-gear or T-bolt style clamp. The clamping range of 42.40 mm to 45.50 mm accommodates standard hose ODs in this size class.

Key Features

• Single-ear stepless design provides uniform radial clamping force around the full hose circumference
• Stainless steel construction resists corrosion in wet, chemical, and outdoor environments
• 7 mm band width distributes load evenly to reduce hose deformation
• 0.6 mm wall thickness keeps the clamp profile low in tight-clearance installations
• Clamping range of 42.40 mm to 45.50 mm suits standard 1-3/4 inch OD hose and tubing
• Ear inner width of 10 mm (0.394 inches) is compatible with standard OETIKER crimping pincers

Compatibility

Designed as an OEM-style replacement or new-installation one-ear clamp for 1-3/4 inch nominal hose and tubing connections in plumbing, HVAC, automotive, and fluid-handling assemblies.

Installation Notes

Installation requires a calibrated ear-clamp pincer tool; do not substitute with standard pliers, as uneven crimping will compromise the seal. Shut off fluid flow and depressurize the line before fitting or removing any hose clamp. Verify the hose OD falls within the 42.40 mm to 45.50 mm clamping range before crimping. Once crimped, the ear clamp is a single-use fastener and must be cut off and replaced if the connection is reopened.
