Oetiker 16700016-100 Ear Clamp 5/8 Inch Stainless Steel

Product Description

The OETIKER 16700016-100 is a single-ear hose clamp designed for permanent, low-profile connections on flexible tubing and hose assemblies. The ear is crimped shut with a pincer tool, creating a 360-degree radial clamping force that prevents loosening from vibration or thermal cycling. The band measures 7 mm wide and 0.60 mm thick, and the nominal clamp size is 5/8 inch. Constructed from stainless steel throughout, this clamp resists corrosion in wet, refrigerant-adjacent, or chemically active environments. HVAC technicians, plumbers, and automotive-fluid techs use this style of clamp where a standard worm-drive or spring clamp would add too much bulk or require re-torquing over time.

Ear clamps in the 5/8 inch nominal size are commonly used on low-pressure coolant lines, condensate drain tubing, radiant heating supply and return connections, potable water flexible fittings, and refrigerant-side accessory lines. They are also found on pool equipment plumbing where barbed fittings connect flexible PVC tubing. The single-ear design keeps the clamp body outside the tube bend radius, making it suitable for tight-space installations in equipment cabinets and air handler compartments.

Key Features

• Single-ear crimp design provides permanent, tamper-evident clamping with no re-torque required
• Stainless steel construction resists corrosion in wet and chemically active service environments
• 7 mm band width distributes clamping load evenly across the hose bead
• 0.60 mm band thickness balances flexibility during crimping with strength after installation
• Low-profile ear sits close to the hose surface, suitable for confined installation spaces
• 5/8 inch nominal size fits standard barbed fittings in HVAC, plumbing, and pool applications

Compatibility

Designed as an OEM-style replacement or new-installation ear clamp for 5/8 inch nominal flexible hose and tubing connections in HVAC, plumbing, and pool equipment applications.

Installation Notes

Installation requires an Oetiker-style ear clamp pincer or equivalent crimping tool rated for single-ear clamps — do not attempt to close the ear with pliers, as uneven force will deform the band and compromise the seal. Shut off fluid flow and relieve any line pressure before removing an existing clamp or seating a new one. Follow applicable codes such as the International Plumbing Code or manufacturer assembly guidelines for hose-barb engagement depth before crimping. Inspect the crimped ear after installation to confirm the ear is fully closed with no visible gap.
