Your mechanics are going through a box of gloves a day. They double-glove because one layer isn't enough. Or they've stopped wearing them altogether because it's not worth the hassle. The cause is almost always the same: the wrong thickness for the job.
Why gloves keep tearing
Most cheap disposable nitrile gloves are 3 to 4 mil thick — one mil is one thousandth of an inch, not a millimetre. That thickness works fine for medical use or food prep. In a garage, you're dealing with sharp bolt threads, rough metal edges and tools. A 3 mil glove that catches on a component will tear almost every time.
Real mechanics who use disposable gloves regularly are clear about this: at 5 mil you'll still need 3 to 4 pairs to get through a full working day, but at 8 mil a single pair will typically last half a day or more on mixed mechanical work. The fix isn't ordering more gloves — it's ordering thicker ones.
- 3–4 mil — driving customer vehicles, inspections, very light tasks. Not for chemicals or sharp components
- 5–6 mil — oil changes, brake checks, general servicing. The right balance for most everyday garage work
- Heavy duty (6 mil+) — engine stripping, extended chemical contact, rough work on sharp components
Why nitrile — and not vinyl or latex
Vinyl is not suitable for garage work. It tears easily, offers weak chemical resistance and is not rated for petroleum-based chemicals.
Latex carries allergy risk — around 1–3% of people have latex sensitivity and it can develop with repeated exposure over time. In a team of even five mechanics, that's a real risk. Nitrile is fully synthetic, no allergy risk.
Nitrile is right for garages for three reasons: it resists engine oil, brake fluid, gear oil, grease and fuel without degrading; it's around three times more puncture-resistant than latex; and it's latex-free, safe for your whole team.
One thing most suppliers won't tell you: nitrile does not resist everything. Brake cleaner, acetone and ketone-based solvents can penetrate nitrile quickly. When your team is using these products, gloves need to be changed frequently — no disposable glove is indefinite protection.
Why it actually matters beyond keeping hands clean
The UK's Health and Safety Executive states that frequent and prolonged contact with used engine oil may cause dermatitis and other skin disorders, including skin cancer. This is a real occupational health risk for mechanics who work with used oil day in, day out — not just a cleanliness issue.
Brake fluid is glycol-based and corrosive — it absorbs through skin and causes irritation with repeated contact. Gloves are a simple, low-cost control measure against hazards that accumulate over a working life.
Black vs blue — does colour matter?
No. Black and blue nitrile at the same thickness perform identically. The difference is purely visual.
Black hides oil, grease and grime — after an engine job, a black glove still looks professional. That's why it's the standard in customer-facing automotive environments like valeting and detailing. Blue is equally good for workshop tasks where appearance doesn't matter, or where you colour-code tasks between team members.
How much do you actually need?
A mechanic on mixed work gets through 10 to 20 pairs in a full day. A team of five needs roughly 10 to 20 boxes of 100 per week to keep working without running out.
If you're ordering reactively and running out mid-week, our Subscribe & Save 15% plan sets up a regular monthly delivery at a reduced price — sized to your team, adjustable any time. For larger operations, we offer pallet deals and £500 Instant Credit for established UK businesses — order by purchase order, pay within 30 days, no application needed.
FAQ
Are black nitrile gloves stronger than blue?
No. Same material, same strength at the same thickness. The colour difference is cosmetic only.
What thickness for brake work?
5–6 mil minimum. Change immediately if the glove shows any swelling or softening from chemical contact.
Do nitrile gloves resist brake cleaner?
Not reliably. Ketone-based solvents like brake cleaner can penetrate nitrile quickly. Change gloves frequently when using them.
How many boxes does a workshop of five need per week?
Around 10 to 20 boxes of 100 per week for mixed mechanical work. Our team can help you work out the right quantity based on your team size and work type.
