Oetiker 15500039-100 1-ear Clamp 2-3/8 Inch

Product Description

The OETIKER 15500039-100 is a single-ear stepless clamp used to create a permanent, leak-free connection on hoses, tubing, and flexible conduit. The ear is crimped with a pincer tool, collapsing it uniformly to lock the clamp at a set diameter with no over-tightening risk. This clamp is constructed from stainless steel, giving it corrosion resistance suitable for wet or chemical-exposure environments. With a 7 mm band width and 0.6 mm wall thickness, it seats cleanly inside tight assemblies where worm-drive or T-bolt clamps will not fit. Plumbers, HVAC technicians, and automotive or industrial service professionals install this clamp where a permanent, tamper-evident connection is required.

This clamp fits applications requiring a clamping range of 57.40 mm to 60.50 mm, which corresponds to a nominal outside diameter of 2-3/8 inches. It is commonly installed on PEX transitions, barbed fittings, coolant hoses, drain connections, and other flexible-tubing assemblies in residential and light commercial mechanical systems. The narrow band profile allows use in confined spaces where bulkier clamps are impractical.

Key Features

• Single-ear stepless design crimps to a fixed diameter for a permanent, leak-resistant seal
• Stainless steel construction resists corrosion in wet, humid, and chemical-exposure environments
• 7 mm band width provides secure seating on standard barbed fittings
• 0.6 mm band thickness keeps the clamp profile slim for tight-clearance installations
• Clamping range of 57.40 mm to 60.50 mm suits 2-3/8 inch nominal tubing
• Compatible with standard OETIKER pincer and ear-clamp installation tools

Compatibility

Designed as an OEM-style replacement or service clamp for flexible hose and tubing assemblies requiring a 57.40 mm to 60.50 mm clamping range at a 2-3/8 inch nominal size.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool; do not attempt to crimp with pliers, as uneven force will compromise the seal. Depressurize and drain the line before removing an existing clamp or fitting. Verify the hose or tubing is fully seated on the barb before crimping. Follow applicable plumbing or mechanical codes, such as IPC or IFGC, for the system being serviced.
