Nitrile Glove Thickness Explained: A UK Guide to Mil Ratings

Glove packaging in the UK is full of the words heavy duty, extra strong and industrial grade, and none of them mean anything specific. The number that does mean something is the mil rating, and most retailers bury it.

This guide explains what mil actually measures, what each thickness is genuinely good for, and where the marketing claims fall down. Klevaro stocks disposable and coated gloves, so we have a commercial interest here, and we have tried to write the guide we would want to read rather than a sales page.

What Does Mil Mean on a Nitrile Glove

A mil is one thousandth of an inch. An 8 mil glove measures 0.008 inches at the palm, which is about 0.2mm.

Two things to know before you compare numbers between brands.

First, thickness is usually quoted at the palm. Fingertips are often thicker and the cuff is usually thinner, so a single number describes one part of the glove rather than the whole thing.

Second, mil is not a regulated claim in the way a EN standard is. Some suppliers quote the fingertip figure because it flatters the number. If two gloves are both sold as 6 mil and one feels noticeably flimsier, that is usually why.

The honest summary is that the jump from 6 mil to 8 mil is where a disposable glove stops being a barrier and starts being a working glove.

When 8 Mil Is Worth Paying For

Thicker is not automatically better. You are trading dexterity and cost for durability, so it only pays where the glove would otherwise fail.

8 mil earns its place when:

• You are working with oil, grease, fuel, brake fluid or coolant
• The job involves sharp edges, threads, jubilee clips or swarf
• You need one glove to last a whole task rather than changing every ten minutes
• You are handling solvents, resins, two-part fillers or strong cleaners
• You want a textured grip that still works when your hands are wet

Our own 8 mil black nitrile gloves sit in this bracket. They are a box of 50 with a raised diamond texture, which is the pattern that actually channels oil away rather than just looking rugged.

When You Should Not Buy 8 Mil

This is the part most glove guides skip.

• Fine work. Electronics, watch repair, model making and anything where you need to feel a small component. Go 4 mil, or bare hands.
• Food prep. 3 to 4 mil is standard and 8 mil is wasteful.
• All day wear in heat. Thicker nitrile means sweatier hands. If you are gloved for eight hours, a coated reusable glove is more comfortable.
• Rotating machinery. Never wear loose gloves near bench grinders, pillar drills or table saws. A glove that catches is far more dangerous than a bare hand.
• Rough handling of timber, brick or fencing. A disposable will shred. Use a leather rigger glove instead.

Nitrile, Latex or Vinyl

Nitrile is a synthetic rubber. It resists oils, fuels and solvents well, punctures less easily than latex, and nobody reacts to it the way some people react to latex protein. For workshop and automotive work it is the default choice.

Latex is more elastic and gives slightly better tactile feel at the same thickness. It is cheaper. It degrades in contact with oils and petrol, and a meaningful number of people are allergic to it, which is why most trade suppliers have moved away.

Vinyl is the cheapest and the weakest. It is fine for short food handling tasks and poor at almost everything else.

There is a fourth option people forget: coated reusable gloves. A knitted liner with a nitrile or latex palm coating gives you grip and abrasion resistance for weeks rather than one job. Rolson Tools makes these in nitrile coated, latex coated, foam latex and thermal versions, and for handling rather than contamination they are usually the better buy.

Why Glove Colour Is Not Just Cosmetic

Black nitrile became the workshop standard for a practical reason: it does not show oil and grease, so a glove still looks serviceable after ten minutes under a bonnet and people keep wearing it rather than binning it.

Blue is used in food and medical settings deliberately, because a torn fragment is easy to spot against food. Some kitchens will not accept black gloves for that reason.

Colour has no bearing on strength. An 8 mil blue glove and an 8 mil black glove perform identically.

How to Size Disposable Gloves

Measure the circumference of your hand around the widest part of the palm, excluding the thumb.

• Around 8 inches: Medium
• Around 9 inches: Large, the most commonly ordered size in the UK
• Around 10 inches: X-Large

If you are between sizes, size up. A tight 8 mil glove is genuinely hard to pull on with damp hands, and it will tear at the cuff as you drag it on.

What the EN Standards on the Box Actually Mean

• EN 420: the general requirement for protective gloves. Sizing, harmless materials, marking. Baseline, not a performance claim.
• EN ISO 374-1: chemical protection. The Type letter matters. Type A passes six chemicals, Type B three, Type C one.
• EN ISO 374-5: protection against micro-organisms.
• CE marking: conformity, followed by the notified body number.

If a glove is sold as chemical resistant with no EN ISO 374-1 Type letter next to it, treat the claim as marketing.

How Many Gloves Should You Actually Buy

Boxes of 100 look better value per glove and are the default in most of the trade. They are the right call if you get through gloves daily.

If you are a home mechanic, a small van operation or a workshop that gloves up a few times a week, a box of 50 is the more sensible unit. Nitrile has a shelf life of around three years, so a big box bought for a once-a-month job can perish before you finish it.

Buying smaller also lets you try a thickness before committing. If you have only ever used 5 mil, one box of 8 mil will tell you quickly whether the extra cost is worth it for your work.

Where to Buy Work Gloves in the UK

Klevaro stocks both ends of this. The nitrile and work gloves range covers 8 mil disposables through to coated reusables and leather riggers, all in UK stock with same day dispatch.
