Oetiker 15300004-100 1-ear Clamp 1/4 Inch Stainless Steel

Product Description

The OETIKER 15300004-100 is a single-ear (stepless) hose clamp designed for permanent, low-profile hose and tubing connections. The ear deforms permanently when crimped, creating a uniform 360-degree seal without sharp edges or rotation points. Constructed from stainless steel with a band width of 0.157 inches and a band thickness of 0.02 inches, this clamp maintains consistent clamping force across the full clamping range of 5.10 mm to 6.10 mm. It is installed by HVAC technicians, plumbers, and automotive service professionals wherever a reliable, vibration-resistant clamp is required on small-diameter tubing or hose assemblies.

This 1/4-inch nominal clamp is suited for small-bore applications including refrigerant line insulation sleeves, low-pressure coolant hoses, drain tubing, and similar connections found in residential and light commercial HVAC systems, plumbing assemblies, and fluid-handling equipment. The compact profile fits in tight spaces where worm-drive or T-bolt clamps are impractical. The ear width of 3.20 mm provides a consistent crimp point for standard pincer-style installation tools.

Key Features

• Single-ear stepless design creates a permanent, uniform 360-degree seal when crimped
• Stainless steel construction resists corrosion in wet and humid service environments
• Band width of 0.157 inches and thickness of 0.02 inches for a low-profile fit in confined spaces
• Clamping range of 5.10 mm to 6.10 mm suits standard 1/4-inch nominal hose and tubing
• Ear inner width of 3.20 mm is compatible with standard OETIKER-style pincers and crimping tools
• No sharp external edges after crimping, reducing risk of abrasion to adjacent components

Compatibility

Designed as an OEM-style replacement or original-installation clamp for 1/4-inch nominal hose and tubing connections requiring a stepless ear-clamp fastening method.

Installation Notes

Installation requires a pincer-style or plier-style ear-clamp crimping tool rated for the clamp diameter. Position the clamp over the hose before seating the hose onto the fitting, then crimp the ear fully until the tool stops to avoid partial deformation. Because the clamp is permanent once crimped, confirm hose positioning before installing. Always depressurize and drain the line before servicing any connection this clamp secures.
