SHOWA Atlas 660 Triple-Dipped PVC Chemical-Resistant Gloves

The SHOWA Atlas 660 is a triple-dipped PVC chemical-resistant glove — the rough-service workhorse for oils, acids, and caustics that fisheries, petrochemical decks, and plating lines have run on for decades. Triple dipping builds a thicker PVC wall than the 620 for harder abrasion alongside chemical exposure, and as with any chemical glove, verify your specific chemical against SHOWA's permeation chart before use.

Why the SHOWA Atlas 660 survives rough service

Some jobs punish a glove with both chemicals and abrasion — plating racks, fish holds, oily decks. The Atlas 660 is built for exactly that: three dipped layers of PVC that build a thicker wall than the 620, resisting oils, acids, and caustics while shrugging off the wear that thin gloves cannot. Decades of marine and petrochemical use are the track record. As chemical-resistant gloves go, this is the rough-service PVC pick, and the best chemical-resistant gloves guide and nitrile chemical glove guide explain where PVC beats nitrile and where it does not.

What the SHOWA Atlas 660 listing documents

From the published specs: a triple-dipped PVC shell with a thicker wall than the 620; resistance to oils, acids, and caustics; abrasion durability for rough service; gauntlet-length coverage; reusable construction. These are true pvc chemical resistant gloves and genuine triple dipped pvc gloves — the rough-service showa atlas gloves for marine, plating, and petrochemical work.

How the Atlas 660 compares to other chemical gloves

Match the polymer to the chemistry: for general oils, greases, and solvents with more dexterity, nitrile like the Solvex 37-155 and Solvex 37-175 fit; for aggressive polar solvents, the butyl SHOWA 874 is required; and for incidental splash, the disposable TouchNTuff 92-600. Other options include the SHOWA 727 nitrile, the elbow-length SHOWA Atlas 772, and the Liberty 2570SP neoprene-latex. The nitrile-vs-latex guide and nitrile-vs-vinyl guide cover polymer selection.

Choosing the right glove for your hazard

Chemical resistance and abrasion are separate from cut protection — the 660 is abrasion-tough but not cut-rated, so for sharp edges see the cut-resistant gloves guide and the cut-resistant collection. For blended nitrile-neoprene resistance, see the Microflex 93-260; the nitrile gloves collection covers everyday chemical work, and the full hand protection collection spans every category.

Where it fits by job and crew orders

The triple-dipped PVC 660 suits fisheries, petrochemical decks, plating lines, food processing, janitorial, and washdown work — anywhere hands face oils, acids, or caustics in wet, abrasive conditions that would chew through a thinner glove — so compare polymers with the chemical glove guide and confirm compatibility on SHOWA's permeation chart.
