Oetiker 10500340-100 1-ear Clamp 3/4 Inch Carbon Steel

Product Description

The OETIKER 10500340-100 is a single-ear stepless clamp used to create permanent, vibration-resistant connections on hose and tubing assemblies. Manufactured from carbon steel with a zinc-plated head coating, this clamp features a 7.00 mm band width and 0.75 mm band thickness. The ear design allows the clamp to be closed with standard ear-clamp pliers or a pneumatic pincer tool, producing a consistent 360-degree radial compression on the hose. HVAC technicians, plumbers, and automotive service professionals commonly install this style of clamp on flexible hose connections where a reusable worm-gear clamp is not acceptable.

This clamp is suited for 3/4 inch nominal hose applications across residential and light commercial systems, including refrigerant-line insulation jackets, coolant hoses, condensate drain tubing, and similar flexible hose-to-barb connections. The clamping range of 17.00 mm to 19.80 mm accommodates standard 3/4 inch OD tubing and hose assemblies. It is sold individually with a minimum order quantity of 10 units, making it appropriate for stocking in a service van or shop inventory.

Key Features

• Single-ear stepless design provides uniform 360-degree clamping force
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7.00 mm band width and 0.75 mm band thickness for consistent seating on hose barbs
• Clamping range of 17.00 mm to 19.80 mm suits standard 3/4 inch nominal hose
• Compatible with standard ear-clamp pincer tools for fast, repeatable installation
• Permanent closure eliminates loosening from vibration or thermal cycling

Compatibility

Designed as an OEM-style replacement or service clamp for 3/4 inch nominal hose and tubing assemblies requiring a permanent single-ear stepless connection.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool or pneumatic equivalent — do not attempt to close the ear with general-purpose pliers, as uneven force will distort the band. Depressurize and drain the line before removing an existing clamp. Position the clamp ear away from any obstruction that could prevent full tool engagement, and verify the hose is fully seated on the barb before closing. Once closed, a single-ear clamp is not reusable and must be cut off for any subsequent service.
