Oetiker 10500331-100 1-ear Clamp 7/8 Inch Carbon Steel

Product Description

The OETIKER 10500331-100 is a 1-ear stepless clamp designed to create secure, permanent connections on hose assemblies, tubing, and fluid-transfer lines. It is manufactured from carbon steel with a zinc-plated head coating for corrosion resistance. The clamp has a nominal size of 7/8 inch, a band width of 7 mm, and a band thickness of 0.75 mm. The ear inner width measures 9 mm (0.354 inches). These clamps are installed using an ear-closing pincer tool that deforms the ear and locks the clamp at a fixed diameter, making them a preferred choice for OEM assembly lines and field service work requiring a tamper-evident, vibration-resistant seal.

The 10500331-100 suits applications in HVAC, plumbing, automotive, and general fluid-handling systems where barbed fittings and flexible hose or tubing must be permanently secured. The clamping range of 19.80 mm to 22.60 mm accommodates standard hose outside diameters in that band. Typical install scenarios include condensate drain lines, coolant hoses, compressed-air tubing connections, and PEX-to-barb fittings. This clamp is appropriate for residential and light commercial installations where a low-profile, single-use closure is specified.

Key Features

• 1-ear stepless design locks at a fixed diameter for a permanent, vibration-resistant seal
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• Clamping range: 19.80 mm to 22.60 mm suits standard 7/8-inch nominal hose OD
• Band width of 7 mm provides stable clamping footprint on barbed fittings
• Band thickness of 0.75 mm balances flexibility with crush strength during ear closure
• Low-profile ear sits flush after installation, reducing clearance concerns in tight spaces

Compatibility

Designed as an OEM-style replacement or service clamp for flexible hose and tubing assemblies with a nominal outside diameter in the 19.80 mm to 22.60 mm clamping range, including barbed fitting connections on condensate, coolant, and fluid-transfer lines.

Installation Notes

Installation requires a dedicated ear-closing pincer or stepless clamp tool; standard pliers will not produce a uniform closure. Position the clamp over the hose before seating the hose onto the barb, then slide the clamp to the proper location per the fitting manufacturer's guidance. Depressurize or drain the line and shut off any associated equipment before servicing existing clamp connections. These clamps are single-use only and must be cut off and replaced if a connection needs to be reopened.
