c.1960s ZIM Hose Clamp Pliers No. 970 by Zim Manufacturing Co. Chicago – Swivel Jaw Automotive Tool
Viridian Eclection
The Piece
A pair of ZIM hose clamp pliers, model No. 970, made by Zim Manufacturing Company of Chicago, Illinois.
The pliers carry swivel jaws and a ratcheting adjustment system, designed for controlled compression of hose clamps in confined engine spaces without slipping or damaging surrounding components.
Construction is solid and utilitarian, steel throughout, with textured metal handles for grip and a mechanical design that prioritizes function over ornament. "ZIM" is stamped on the handle.
It is accompanied by its original branded cardboard box, labeled and printed with specifications and manufacturer details.
History & Provenance
Zim Manufacturing Company of Chicago belonged to a generation of American toolmakers producing specialized equipment for trade use rather than for consumer retail. Tools of this kind were distributed through supply catalogs and professional channels.
The No. 970 answered a narrow need in automotive repair, from a period when mechanics relied on purpose built instruments engineered for durability and repeat use.
The dating to the 1960s rests on the model, the maker and the branded packaging. Because these tools went out through the trade rather than through shops, surviving examples that keep their original box are the less common ones.

Why It Belongs in Your Home
Trade tools have a particular honesty. Nothing on this piece exists for appearance, and that is precisely what gives it presence on a shelf or a workbench.
With its printed box it becomes a small display in its own right, graphics and object together, which suits a workshop, a study, or a case of mid century industrial design.
It remains a clear example of a period when even a niche tool was built with longevity and mechanical intention.
Every piece is packed with professional-grade materials: multiple foam layers, double-boxing, directional and fragile handling labels. For large furniture we use custom timber crating. We photograph packing before dispatch and can provide images on request.

Antiques are irreplaceable and one-of-a-kind. Carrier handling is outside our control once a piece has left our facility, and major carriers including FedEx do not insure antiques.
