Oetiker 16700002-100 Ear Clamp 5/16 Inch Stainless Steel

Product Description

The OETIKER 16700002-100 is a single-ear hose clamp designed for permanent, tamper-resistant connections on small-diameter hose and tubing assemblies. Manufactured from stainless steel, it delivers consistent clamping force when crimped with a standard ear clamp pincer tool. The nominal size is 5/16 inch, with a band width of 5 mm and a band thickness of 0.5 mm. These clamps are commonly installed by HVAC technicians, plumbers, and refrigeration mechanics wherever a low-profile, vibration-resistant hose connection is required. The single-ear design closes to a uniform diameter when pinched, eliminating the unevenness associated with worm-drive clamps in tight-clearance applications.

This clamp is suited for residential and light commercial applications involving small-bore hose connections. Typical uses include condensate drain tubing, refrigerant line insulation jackets, fuel line assemblies, and similar low-pressure hose fittings where a clean, permanent crimp is preferred over a re-usable worm-gear clamp. The 5/16 inch nominal size targets tubing in the 5 to 8 mm outside diameter range. It is sold individually but carries a minimum order quantity of 10 units, making it appropriate for stocking in service vans or shop inventory.

Key Features

• Single-ear design provides uniform clamping force when crimped with a pincer tool
• Stainless steel construction resists corrosion in wet or high-humidity environments
• 5 mm band width and 0.5 mm band thickness for low-profile fitment in tight spaces
• Permanent closure reduces risk of hose pull-off or vibration loosening
• 5/16 inch nominal size suits common small-bore hose and tubing assemblies

Compatibility

Designed as an OEM-style replacement or new-installation clamp for small-diameter hose and tubing with a nominal outside diameter of 5/16 inch, commonly found in HVAC, plumbing, and refrigeration assemblies.

Installation Notes

Installation requires a dedicated ear clamp pincer tool; do not attempt to close the ear with pliers, as uneven force will compromise the seal. Shut off fluid flow and relieve any system pressure before removing or installing hose clamps. Verify hose is fully seated on the fitting barb before crimping. Follow applicable codes such as the International Mechanical Code or IFGC for fuel-gas line hose connections.
