Oetiker 15300003-100 1-ear Clamp 3/16 Inch

Product Description

The OETIKER 15300003-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. With a nominal size of 3/16 inch and a clamping range of 4.10 mm to 5.10 mm, this clamp delivers consistent radial force around small-diameter tubing. The band is 0.157 inches wide and 0.020 inches thick, constructed from stainless steel for corrosion resistance. Installation requires a pincer or ear-clamp tool that crimps the ear closed, locking the clamp permanently in place. Plumbers, HVAC technicians, and fluid-system assemblers use this clamp where a tamper-resistant, leak-free connection is required.

This 1-ear clamp suits small-bore tubing and hose assemblies common in residential and light commercial systems. Typical applications include refrigerant line insulation sleeves, low-pressure fluid tubing, PEX-AL-PEX connections, and automotive or appliance hose fittings where a compact, low-profile clamp is needed. The stainless steel construction makes it suitable for environments where moisture or mild chemical exposure is present. It is sold individually but carries a minimum order quantity of 10 units.

Key Features

• 1-ear stepless design delivers uniform 360-degree clamping force
• Stainless steel construction resists corrosion in wet or humid environments
• Clamping range of 4.10 mm to 5.10 mm suits 3/16 inch nominal tubing
• Band width of 0.157 inches and thickness of 0.020 inches provide a low-profile footprint
• Permanent crimp closure reduces risk of loosening under vibration or pressure cycling

Compatibility

Designed as an OEM-style replacement or new-installation clamp for small-diameter hose and tubing assemblies requiring a 3/16 inch nominal 1-ear stepless clamp.

Installation Notes

Installation requires a calibrated OETIKER-style pincer or equivalent ear-clamp crimping tool rated for the clamp size. Shut off fluid or system pressure before installing or inspecting clamp connections. Ensure tubing is fully seated before crimping, as the 1-ear design creates a permanent, non-removable connection once closed. Follow applicable plumbing or mechanical codes for the system type being serviced.
