Nitrile Glove Thickness Guide: Mil Chart from 3 to 15 Mil

Published October 2026 · Reviewed by Jeff B., Safety Products Specialist

Nitrile glove thickness is measured in mil, or thousandths of an inch. Most nitrile exam gloves are 3 to 5 mil, which keeps touch sensitivity high for patient care and lab work. Gloves of 6 mil and up are considered heavy-duty and are used for automotive, janitorial and industrial work, and disposable nitrile tops out around 10 mil. For anything thicker, such as long contact with chemicals, you move to reusable nitrile gauntlets of 15 mil or more.

What Does "Mil" Mean?

One mil is 0.001 inch, or 0.0254 mm. A 4 mil glove is about 0.1 mm thick; an 8 mil glove is about 0.2 mm. The ASTM D6319 standard for nitrile exam gloves sets a minimum of 0.05 mm (about 2 mil) at both the palm and fingertip, so nearly every exam glove sold is well above the minimum.

Where Thickness Is Measured Matters

Brands don't all measure in the same place. Many quote fingertip thickness, which is usually the thickest point; the palm is often thinner. When comparing two gloves, check whether both figures are fingertip, palm or an average, and compare like with like.

Is Thicker Always Better?

Not always. Thicker nitrile resists punctures and tears better and generally slows chemicals down longer, but it costs touch sensitivity and makes hands warmer and more tired. Choose the thinnest glove that does the job:

• Patient care and lab work: 3 to 5 mil. Fine motor tasks and frequent glove changes favor thinner gloves.
• Tattoo, EMS and cleaning: 5 to 7 mil for more durability without losing much feel.
• Automotive and industrial: 6 to 8 mil for grease, rough parts and longer wear; textured grip helps.
• Heavy-duty and sanitation: 8 to 10 mil, often with an extended cuff.
• Chemical immersion: a 15 mil or thicker reusable gauntlet, chosen with the glove maker's chemical resistance data, not a thicker disposable.

Thickness alone doesn't make a glove right for a chemical. Material matters as much: nitrile resists oils and fuels well, but some solvents, acetone for example, get through it quickly at any disposable thickness. For acetone, use butyl rubber gloves instead.

What Are the Thickest Nitrile Gloves?

Among disposables, about 10 mil is the practical top end; we stock the Raptor Grip 10 mil. Beyond that, nitrile is sold as reusable gloves and gauntlets, such as our 15 mil Liberty 13" green nitrile glove.

FAQ

Is 7 mil thick for a nitrile glove?

Yes. 7 mil is in the heavy-duty range, about twice as thick as a typical exam glove.

Is 4 mil thick enough?

For exams, lab work and food prep, yes. For grease, rough parts or long wear, step up to 6 mil or more.

What's the difference between 6 mil and 8 mil gloves?

8 mil gloves resist tears and punctures better and last longer on rough work; 6 mil gloves keep more dexterity and are easier to change often.

How thick are medical exam gloves?

Most are 3 to 6 mil. Some exam-grade gloves, such as Raven and Raptor Grip, go up to 7 to 10 mil.

Are thicker gloves better for chemicals?

Thicker gloves of the same material usually last longer before a chemical gets through, but the material is the bigger factor. Check the glove maker's chemical resistance data.
