Oetiker 15100004-100 2-ear Clamp 5/16 Inch

Product Description

The OETIKER 15100004-100 is a 2-ear clamp designed for secure, permanent hose and tubing connections in HVAC, plumbing, and fluid-handling applications. Manufactured from stainless steel with a band width of 7.00 mm and a material thickness of 0.80 mm, this clamp is crimped or pinched with a dedicated ear-clamp tool to create a tamper-evident, leak-resistant seal. The nominal size is 5/16 inch, making it suited for small-diameter flexible hose assemblies. Licensed tradespeople and factory assembly technicians rely on ear-style clamps where a one-time, vibration-resistant connection is required over reusable worm-drive alternatives.

This clamp is commonly used in residential and light commercial HVAC condensate drain lines, refrigerant tubing insulation jackets, radiant heating flexible tubing, and plumbing supply connections where small-bore flexible hose is terminated. The 5/16 inch nominal size fits tubing that falls within the 7.00 mm to 9.00 mm clamping range. It is also used in pool and spa equipment plumbing where chemical-resistant, low-profile clamps are preferred over standard screw-type hardware. Installation is performed by HVAC technicians, plumbers, and pipefitters using a standard ear-clamp pincer tool.

Key Features

• Stainless steel construction resists corrosion in wet and chemical-exposure environments
• 7.00 mm band width distributes clamping force evenly across the hose bead
• 0.80 mm material thickness provides consistent deformation during crimping
• Clamping range of 7.00 mm to 9.00 mm suits standard 5/16 inch flexible hose
• 2-ear design creates a permanent, tamper-evident seal not subject to loosening from vibration
• Low-profile ear geometry minimizes clearance requirements in tight installations

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 5/16 inch nominal flexible hose and tubing assemblies within a 7.00 mm to 9.00 mm outside diameter clamping range.

Installation Notes

Installation requires a dedicated ear-clamp pincer or pincers tool; do not attempt to close the ear with pliers, as this will result in uneven deformation and a potential leak path. Shut off all fluid supply and relieve system pressure before removing any existing clamp or fitting. This is a permanent, single-use clamp and cannot be reopened or repositioned once crimped. Follow applicable plumbing or mechanical codes for the jurisdiction, including IPC and IFGC guidelines where relevant to the connected system.
