The SHOWA Atlas 660 is a PVC chemical-resistant glove from SHOWA, stocked at $39.99 — built as triple-dipped PVC in a heavy-duty rough-grip build. It's the pick for rough wet work with oil, acid, and caustic exposure — marine, plating, petrochemical deck duty. This review covers what the listing documents, where it beats its closest rival, and who should buy something else.
Why the SHOWA Atlas 660 Stands Out
Fisheries, petrochemical decks, and plating lines have run on the Atlas 660 for decades because triple-dipping builds a PVC wall that survives abrasion alongside the chemical exposure — the failure mode of thinner dipped gloves. PVC's chart covers oils, acids, and caustics in exactly the rough-service environments where a delicate glove dies in a day.
Specification and Configuration
What the listing commits to: triple-dipped pvc; rough finish; heavy-duty. Claims beyond that — lab numbers, endurance figures, certifications the listing doesn't state — don't appear in this review, because we don't invent them. Size and color options run on the linked Amazon listing rather than as separate stocked variants.
Chemical gloves are selected by polymer against the specific chemical — nitrile for oils and many solvents, butyl for ketones and polar solvents, neoprene for acids and caustics, PVC for rough wet service — and the deciding document is the manufacturer's permeation chart, not the word 'resistant' on a listing. The SHOWA Atlas 660 is the PVC chemical-resistant glove entry in that matrix; the full polymer-sorted lineup lives in our Chemical-Resistant Gloves collection.
Where It Falls Short
Its limits, honestly: Solvent work — PVC performs poorly against many organic solvents; check the chart and reach for nitrile or butyl instead.
Pros and Cons
Pros
- Triple-dipped PVC
- $39.99 — positioned honestly against its ladder
- From SHOWA — the reference brand in jobsite cooling
- Listing states its construction claims plainly
Cons
- Single-listing size/color selection happens on Amazon, not as stocked variants
- Solvent work
Who Should Buy It
Order the SHOWA Atlas 660 if you are rough wet work with oil, acid, and caustic exposure — marine, plating, petrochemical deck duty.
Who Should Skip It
Skip it for solvent work — PVC performs poorly against many organic solvents; check the chart and reach for nitrile or butyl instead.
How It Compares
The 620 is the double-dipped version at a fraction of the listed price — same PVC chemistry, lighter wall. Buy the 660 where abrasion kills gloves; buy 620s by the box everywhere else. The Chemical-Resistant Gloves collection carries the complete ladder so you can compare every tier. Head-to-head rival: SHOWA Atlas 620.

Frequently Asked Questions
What is the SHOWA Atlas 660 made of?
Per the listing: triple-dipped pvc; rough finish; heavy-duty. That's the documented construction — anything beyond it belongs to the manufacturer's spec sheet, not this review.
How much does the SHOWA Atlas 660 cost?
$39.99 at the linked Amazon listing. Prices track the live listing, and size or color selections there can shift the number.
SHOWA Atlas 660 vs SHOWA Atlas 620 — which should I buy?
The 620 is the double-dipped version at a fraction of the listed price — same PVC chemistry, lighter wall. Buy the 660 where abrasion kills gloves; buy 620s by the box everywhere else.
Who is the SHOWA Atlas 660 best for?
Rough wet work with oil, acid, and caustic exposure — marine, plating, petrochemical deck duty.
When should I skip the SHOWA Atlas 660?
Solvent work — PVC performs poorly against many organic solvents; check the chart and reach for nitrile or butyl instead.
What sizes does the SHOWA Atlas 660 come in?
The size run (and color options where offered) lives on the linked Amazon listing — we deliberately don't restate it, because listings update. Check the size chart there before ordering.
Is SHOWA a good brand?
SHOWA (formerly SHOWA-Best, home of the Atlas line) is one of the most established names in dipped and chemical gloves — the Atlas 620/660 PVC gloves and the 700-series nitrile family have been industrial staples for decades. Model numbers are stable and its chemical-resistance guide documents the claims.
What chemicals does the SHOWA Atlas 660 protect against?
The ones its polymer handles per the manufacturer's permeation chart — 'chemical resistant' is never a blanket claim. Look up your specific chemical and required contact time in SHOWA's chemical-resistance guide before relying on any glove; breakthrough times differ by orders of magnitude across chemistries.
What do permeation and breakthrough time mean for the SHOWA Atlas 660?
Permeation is chemical movement through an intact glove at the molecular level; breakthrough time is how long that takes at test conditions. A glove that visibly survives a solvent can still be passing it through to your skin — which is why selection runs on published breakthrough data, not on whether the glove looks fine.
Can the SHOWA Atlas 660 be reused, and how should it be decontaminated?
Yes — rinse per the manufacturer's care guidance before removal, dry fully, and inspect for swelling, stiffening, or color change before each reuse. A glove that has absorbed its chemical keeps permeating from within; degradation signs retire it regardless of age.
Does OSHA require chemical-resistant gloves like the SHOWA Atlas 660?
OSHA 29 CFR 1910.138 requires employers to select hand protection appropriate to the hazard identified in their assessment — for chemical exposures that means a glove whose polymer and breakthrough data match the chemical and task duration. The HazCom SDS for each chemical names the protective-glove requirement the assessment must satisfy.
What thickness is the SHOWA Atlas 660, and does mil rating matter?
Per the listing: triple-dipped pvc; rough finish; heavy-duty. Thickness buys durability and (usually) longer breakthrough, at the cost of dexterity — but polymer choice matters far more than mil count. A thin glove of the right polymer beats a thick glove of the wrong one every time.
Lined or unlined — which configuration of glove like the SHOWA Atlas 660 should I buy?
Flock lining absorbs sweat and makes full-shift wear tolerable; unlined gloves decontaminate faster, shed no lint into the process, and dry quicker between cycles. Assign by task: lined for continuous dry-side handling, unlined for wash-down and lint-sensitive work.
When should I use a disposable instead of a reusable chemical glove (or vice versa)?
Disposables for incidental contact and splash — strip and bin with the contamination. Reusables for immersion, sustained contact, and abrasive handling, where a 5-mil film would fail mechanically long before the chemistry got through. The crossover mistake is using disposables for immersion; that's how breakthrough happens mid-task.
What other PPE pairs with the SHOWA Atlas 660 for chemical work?
Splash protection scales with the task: chemical splash goggles over safety glasses, a face shield for pouring and transfer, and chemical-resistant aprons or coveralls for anything that can wet clothing. The glove is one layer of the chemical PPE assessment, not the whole answer.
The Bottom Line
The SHOWA Atlas 660 does its job at its price: triple-dipped PVC in a heavy-duty rough-grip build at $39.99. Rated 4.6/5 on documented spec, configuration, and value for the intended buyer.
