Oetiker 15500058-100 1-ear Clamp 3.5 in Stainless

Product Description

The OETIKER 15500058-100 is a single-ear stepless clamp designed to create a permanent, vibration-resistant seal on hose and tubing connections. Manufactured from stainless steel with a 0.6 mm wall thickness and a 7 mm band width, this clamp is installed using a standard ear-closing pincer tool that deforms the ear to lock the clamp at the correct diameter. It is widely used by plumbers, HVAC technicians, and automotive service professionals wherever a low-profile, leak-free crimp connection is required. The nominal size is 3.5 inches, with a clamping range of 85.9 mm to 89.0 mm.

This clamp is suited for residential and light commercial applications involving flexible hose, coolant lines, drain connections, and similar tubing assemblies. The single-ear design makes it a good fit in confined spaces where traditional worm-drive or T-bolt clamps are impractical. It is a common choice for PEX transitions, heater hose terminations, and condensate drain fittings where a tamper-evident, one-time-set clamp is preferred over a reusable style.

Key Features

• Single-ear stepless design provides a uniform 360-degree clamping force around the hose
• Stainless steel construction resists corrosion in wet and humid environments
• 7 mm band width distributes load evenly to reduce hose deformation
• 0.6 mm band thickness maintains consistent geometry through the crimping process
• Clamping range of 85.9 mm to 89.0 mm suits standard 3.5-inch nominal hose and tubing
• Low-profile ear sits close to the hose surface, allowing use in tight installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 3.5-inch nominal hose and tubing assemblies requiring a single-ear stepless crimp fitting.

Installation Notes

Installation requires an OETIKER-style ear-closing pincer or equivalent crimping tool rated for single-ear clamps. Verify the hose or tubing is fully seated on the fitting before crimping, as the single-ear clamp cannot be reopened or repositioned after the ear is closed. Follow applicable plumbing or mechanical codes, including IPC or IFGC requirements, for the specific connection type being serviced. Wear eye protection during crimping operations.
