Oetiker 15300012-100 1-ear Clamp 3/8 Inch Stainless Steel

Product Description

The OETIKER 15300012-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections. Manufactured from stainless steel, this clamp is crimped with a standard ear-closing tool to create a uniform 360-degree seal. It carries a nominal size of 3/8 inch, a clamping range of 8.10 to 9.50 millimeters, a band width of 0.276 inches, and a band thickness of 0.039 inches. Licensed HVAC technicians, plumbers, and fluid-system assemblers use this clamp wherever a vibration-resistant, low-profile connection is required in tight spaces or high-cycle applications.

The 15300012-100 fits residential and light commercial applications including refrigerant tubing assemblies, coolant hoses, pneumatic lines, and plumbing quick-connect fittings. Its compact ear profile makes it well suited to confined equipment cavities and manifold connections where conventional worm-drive clamps will not fit. Installers working on hydronic systems, radiant tubing, and PEX barb fittings commonly specify this clamp style for both new construction and retrofit work.

Key Features

• Stainless steel construction resists corrosion in wet and chemical-exposure environments
• 1-ear design allows single-point crimping for fast, consistent installation
• Clamping range of 8.10 to 9.50 mm accommodates standard 3/8 inch nominal hose and tubing
• Band width of 0.276 inches and thickness of 0.039 inches deliver a low-profile, vibration-resistant joint
• Stepless internal band provides uniform radial pressure around the full circumference

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 3/8 inch nominal hose and tubing assemblies requiring a permanent, crimped connection.

Installation Notes

Installation requires a calibrated ear-closing or pincer-type crimping tool rated for stepless clamps of this band width. Shut off fluid supply and depressurize the line before removing any existing clamp or fitting. Seat the hose fully onto the barb before positioning the clamp ear over the barb bead, then crimp in a single smooth stroke. Inspect the closed ear for full closure and uniform deformation before returning the system to service.
