Oetiker 10500335-100 1-ear Clamp 1-3/4 Inch

Product Description

The OETIKER 10500335-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from carbon steel with a zinc-plated head coating, this clamp features a 7 mm band width and 0.75 mm band thickness. The single-ear design is compressed with a pincer tool to create a 360-degree radial clamping force that eliminates loosening over time. It is sized for a nominal 1-3/4 inch application with a clamping range of 42.40 mm to 45.50 mm, making it suitable for moderate-diameter hose and tubing assemblies. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of clamp in refrigerant line sets, coolant hoses, PEX fittings, and similar connections.

This clamp is used in residential and light commercial installations where a vibration-resistant, tamper-evident connection is required. Typical applications include PEX tubing terminations at press or barb fittings, coolant and radiator hose assemblies, and low-pressure fluid transfer lines. The zinc-plated head coating provides corrosion resistance for installations in damp or exposed mechanical spaces. The minimum order quantity is 10 units, making this clamp practical for service technicians stocking standard clamp sizes for repeat installations.

Key Features

• Single-ear stepless design delivers uniform 360-degree clamping force when compressed
• Carbon steel construction with zinc-plated ear for corrosion resistance
• 7 mm band width and 0.75 mm band thickness for consistent grip on hose and tubing
• Clamping range of 42.40 mm to 45.50 mm suits nominal 1-3/4 inch diameter connections
• Permanent, tamper-evident closure resists loosening from vibration and thermal cycling

Compatibility

Designed as an OEM-style 1-ear stepless clamp for nominal 1-3/4 inch hose and tubing connections in plumbing, HVAC, and fluid-handling assemblies where a clamping range of 42.40 mm to 45.50 mm is required.

Installation Notes

Installation requires an OETIKER-style single-ear pincer or equivalent crimping tool rated for the clamp diameter. Verify hose or tubing is fully seated on the fitting barb before compressing the ear. Inspect the compressed ear after crimping to confirm complete closure with no visible gap. This type of clamp is not reusable once compressed and must be cut off for removal.
