Oetiker 10500336-100 1-ear Clamp 1-7/8 Inch

Product Description

The OETIKER 10500336-100 is a 1-ear stepless clamp designed to create a secure, permanent connection on hose assemblies, boots, and tubing. The single-ear design is crimped with a pincer tool, collapsing the ear to lock the clamp at a fixed diameter without the risk of over-tightening. Constructed from carbon steel with a zinc-plated head coating, this clamp provides corrosion resistance in light-duty fluid and air line applications. The band measures 7.00 mm wide and 0.75 mm thick, with a clamping range of 45.40 mm to 48.50 mm. Licensed plumbers, HVAC technicians, and automotive service professionals install this type of clamp where a clean, low-profile crimp is required.

The 10500336-100 is suited for residential and light commercial applications involving coolant lines, heater hoses, vacuum lines, condensate drain connections, and similar flexible tubing assemblies. The 1-7/8 inch nominal size fits tubing in the 45.40 mm to 48.50 mm outside diameter range. It is commonly installed during hose assembly fabrication or field repair work where a reusable band clamp is not acceptable and a permanent, tamper-evident connection is needed.

Key Features

• Single-ear stepless design crimps to a fixed diameter for a permanent, vibration-resistant seal
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7.00 mm band width and 0.75 mm band thickness provide consistent clamping force across the ear
• Clamping range of 45.40 mm to 48.50 mm suits 1-7/8 inch nominal hose and tubing
• Low-profile ear profile allows installation in tight clearance areas
• Compatible with standard Oetiker pincer and ear-clamp crimping tools

Compatibility

Designed as an OEM-style 1-ear stepless clamp for flexible hose and tubing applications in the 45.40 mm to 48.50 mm outside diameter range across HVAC, plumbing, and fluid-line assemblies.

Installation Notes

Installation requires a dedicated ear-clamp pincer or crimping tool rated for 1-ear stepless clamps. Power down or de-pressurize the system and drain any fluid before removing an existing clamp or installing this one. Once crimped, the clamp is not reusable and cannot be re-opened without cutting. Verify the hose or tubing outside diameter falls within the stated clamping range before crimping to ensure a leak-free joint.
