Description

This is a specialized industrial stepless ear clamp used primarily in automotive or plumbing applications to secure hoses. It is not a piece of jewelry or a gold item. The '110.5' stamp indicates the open diameter size, not a gold fineness. Its design ensures a 360-degree seal through its unique overlapping inner band.

Key Features

Stepless inner ring design, mechanical 'ear' for crimping, and distinct metric sizing stamps.

Color & Finish

Dull grey metallic with a matte industrial finish; significant surface scuffing and black grease residue.

Hallmarks & Stamps

'OET' (Oetiker Brand), '110.5' (Diameter in mm), 'CAT' or 'PAT' (Patent/Catalog reference).

Dimensions Estimate

Approximately 110.5mm diameter, 7-10mm band width.

Gemstones & Inlays

None

Clasp & Closure

Ear-style crimp closure designed for permanent industrial sealing.

Chain & Links

Solid flat band construction with mechanical interlocking 'tongue-in-groove' design.

Craftsmanship Details

Precision stamped and formed stainless steel with burr-free edges designed for high-pressure durability.

Authentication Indicators

Characteristic Oetiker 'OET' stamp and metric size markings; magnetic properties consistent with ferrous metal.

Origin & Maker

Oetiker Group (Switzerland/Global); high-reputation industrial engineering manufacturer.

Era & Period

Contemporary Industrial (Late 20th Century to Present)

Age Estimate

Modern (likely within the last 10 years based on stamp style).

Cultural Significance

Represents the evolution of modern fluid dynamics and automotive safety engineering.

Condition Notes

Poor (as an accessory), Fair (as hardware). Shows heavy usage, surface scratches, and environmental grime.

Value Estimate

Melt value is negligible (scrap steel). Retail replacement value is approximately $2.00 - $5.00 USD.

Care & Maintenance

Clean with degreaser; store in a dry environment to prevent surface oxidation. Not intended for skin contact.

Similar Items

Worm gear clamps, T-bolt clamps, or pex cinch rings. Often mistaken by novices for precious metal bands due to the large numerical stamps.

Interesting Facts

Oetiker invented the ear clamp in 1942; they are now standard in almost every automobile for CV boots and fuel lines.
