Oetiker 15300020-100 1-ear Clamp 1/2 Inch Stainless Steel

Product Description

The OETIKER 15300020-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from stainless steel, this clamp provides corrosion resistance and long-term holding strength. The ear-style design is crimped with a standard pincer tool, creating a uniform 360-degree seal around the hose or fitting. The band is 0.236 inches wide and 0.031 inches thick, with a clamping range of 10.80 mm to 12.80 mm, making it suitable for nominal 1/2 inch connections. Licensed trade professionals and experienced installers rely on this clamp type for leak-free joints in pressurized systems.

This clamp is commonly used in residential and light commercial plumbing, PEX tubing installations, hydronic heating systems, and HVAC refrigerant-line or condensate assemblies where a tamper-evident, non-adjustable clamp is specified. It is well-suited for applications where vibration or movement could loosen a screw-type clamp over time. The 1-ear configuration is the standard choice when a single crimp point is required for the fitting diameter and hose wall thickness being used.

Key Features

• 1-ear stepless design creates a permanent, uniform seal when crimped
• Stainless steel construction resists corrosion in wet and high-humidity environments
• Band width of 0.236 inches and thickness of 0.031 inches for consistent grip distribution
• Clamping range of 10.80 mm to 12.80 mm fits nominal 1/2 inch hose and tubing connections
• Compatible with standard pincer-type ear clamp installation tools
• Single-use, tamper-evident design confirms connection integrity after installation

Compatibility

Designed as an OEM-style replacement and standard-fitment clamp for nominal 1/2 inch hose and tubing connections in plumbing, HVAC, and fluid-handling assemblies requiring a 1-ear stepless clamp.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified tradespeople using a pincer-type ear clamp tool rated for this clamp size. Shut off and depressurize the system before removing any existing clamps or fittings. The 1-ear clamp is a single-use fastener and must not be reused once crimped. Verify the clamping range matches the hose outer diameter and wall thickness before installation to ensure a leak-free joint.
