Oetiker BD-24049-1/4 2-ear Clamp 0.25 Inch

Product Description

The OETIKER BD-24049-1/4 is a 2-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. The two-ear design deforms during installation to create a uniform 360-degree grip around the hose, eliminating leak paths without the stress concentration of worm-drive or screw clamps. With a nominal size of 0.25 inches and a 6 mm band width, this clamp suits small-diameter hose assemblies where a clean, low-profile crimp is required. Installation requires a pincer-style ear clamp tool and is performed by licensed plumbers, HVAC technicians, and refrigeration mechanics.

This clamp is suited for residential and light commercial applications involving small-bore hoses and tubing, including coolant lines, drain lines, fuel vapor lines, and pneumatic fittings. The 5.00 mm to 7.00 mm clamping range accommodates standard 0.25-inch nominal hose ends. It is commonly used in tight spaces where bulkier clamp styles are impractical, and where a permanent, tamper-resistant connection is preferred over a reusable band clamp.

Key Features

• 2-ear stepless design creates a uniform 360-degree crimp for leak-free connections
• Nominal size of 0.25 inches with a clamping range of 5.00 mm to 7.00 mm
• 6 mm band width provides stable, even compression across small-diameter hose ends
• Low-profile finished profile fits in confined spaces and tight assemblies
• Single-use permanent installation eliminates clamp backing or loosening over time

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 0.25-inch nominal small-bore hose and tubing assemblies in plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation requires a dedicated ear clamp pincer tool; do not attempt to seat the ears with pliers or general-purpose tools, as uneven deformation will compromise the seal. Shut off fluid supply and depressurize the line before fitting or removing hoses. Follow applicable plumbing or mechanical codes, including IPC and IFGC references for fuel and gas line connections. Inspect the hose end for cuts or abrasions before clamping, as surface damage will prevent a proper seal regardless of clamp condition.
