How to specify gloves for Jet A-1, diesel and fuel hose handling, including coating choice, EN ISO 374 testing, EN 16350 anti-static limits, MOQ and factory sampling realities.
Start With the Actual Fuel Task
Most glove failures on refuelling work are not instant chemical burns. They are slower and harder to catch at incoming inspection: nitrile swells after repeated Jet A-1 splash, PVC stiffens on cold morning shifts, grip disappears on a wet aluminium nozzle, then the buyer receives complaints after 10 to 15 shifts. A 13-gauge polyester liner with sandy nitrile palm may pass EN 388:2016+A1:2018 for abrasion and tear, but that does not make it a chemical glove under EN ISO 374-1:2016+A1:2018. Before asking any factory for a price, split the job into 3 exposure levels. Dry hose dragging, coupling and drum movement are mainly mechanical tasks, so request EN 388 data, coating coverage and liner gauge. Intermittent diesel, Jet A-1 or hydraulic oil splash needs a liquid-resistant coating, usually nitrile, PVC or a nitrile-PVC compound, with clear limits on splash duration. Continuous hand contact with fuel, tank cleaning, spill response or sump work should move to a full chemical glove with a 300 mm to 350 mm cuff and permeation data from the exact compound. GloveMark can make OEM knit-dip and sewn support gloves for dry handling and splash-level work. We do not sell a sandy nitrile work glove as an immersion glove. If a tender asks for named-fuel permeation against Jet A-1, diesel EN 590 or Skydrol-type hydraulic fluids, we need a lab test plan, retained samples and realistic development time.
Nitrile, PVC and Neoprene Are Not Interchangeable
Nitrile is the usual starting point for fuel handling gloves because it resists many oils better than latex and gives better dexterity than thick PVC. A practical airport ground-support spec is a 13-gauge nylon or polyester shell, full flat nitrile dip to the wrist, then a sandy nitrile palm over-dip. Total coating thickness is commonly around 0.7 mm to 1.1 mm, depending on mould, compound viscosity and how soft the buyer wants the glove to feel. Too thin and the glove wets through quickly; too thick and size 9 operators complain about trigger feel on nozzles. PVC is cheaper and durable for wet abrasion, but it is bulkier. A PVC glove on cotton interlock or jersey liner can work for diesel pumps, oily drums, waste oil handling and maintenance yards where fine finger control is less important. In cold yards below about 5 C, some PVC compounds become noticeably stiffer, so do not approve samples only in a warm office. PVC also has plasticiser choices that affect feel and chemical performance; changing compound after approval should trigger a new sample review. Neoprene and nitrile-neoprene blends can perform better against some fuel blends, solvents and additives, but they are usually outside a normal Yiwu knit-dip work glove line. They often need dedicated chemical glove tooling and EN ISO 374 or ASTM F739 testing. We can source or co-develop this route, but MOQ, mould cost and test cost are different from a standard 3,000-pair coated glove order.
Static and Flame Risk Need Separate Decisions
Anti-static is not a decoration term. If the buyer needs electrostatic dissipative performance, quote against EN 16350:2014. The key requirement is vertical resistance below 1.0 x 10⁸ ohms under the standard test conditions. That normally means conductive carbon yarn, stainless steel fibre or another conductive path in the liner. A black 15-gauge nylon glove with black nitrile coating can still fail EN 16350 if the coating insulates the hand from the work surface. For OEM sampling, we need to know whether the conductive yarn is required in the full liner or only in selected courses. A common compromise is a 13-gauge nylon-carbon liner with nitrile coating, but the coating coverage matters. A full double dip can reduce breathability and may affect resistance readings if the conductive path is blocked. Do not approve an anti-static glove from colour alone; ask for the EN 16350 test report and check that the article code, liner and coating match the sample. Flame resistance is a separate specification. EN 407:2020 covers thermal risks, but many fuel depot gloves are not flame-resistant. A nitrile-coated nylon or polyester liner can melt near flame even if it handles oily hoses well. For refinery or ATEX zone tenders, send the actual PPE clause before sampling. If flame performance is required, the material stack may need aramid, modacrylic, FR viscose, treated leather or a certified FR coating system. GloveMark will not mark a nylon nitrile glove as flame-resistant without valid material construction and test data.
Grip Pattern Should Match the Wet Surface
Grip claims in catalogues are often too soft. The real question is what the glove does on a diesel film over knurled aluminium, rubber hose, painted steel and brass fittings. Smooth nitrile is easier to wipe clean but can slide on wet couplings. Foam nitrile breathes well on dry assembly lines, but its open structure can absorb oil and break down faster around fuel. Sandy nitrile over a full flat nitrile barrier is usually a safer refuelling compromise because the first layer helps block liquid and the second layer adds bite. For a first sample, we would usually build a 13-gauge polyester or nylon liner, full flat nitrile dip, sandy nitrile palm over-dip, elastic knit cuff and optional thumb crotch reinforcement. Thumb crotch patches can be nitrile-coated synthetic leather or extra dipped reinforcement, useful where the hose coupling rubs the same point all shift. If the work includes wet sleeve exposure, move from knit cuff to a gauntlet or safety cuff; a 240 mm knit-cuff glove is not a substitute for a 300 mm chemical cuff. Cold outdoor fuelling changes the design. A 10-gauge acrylic terry liner or brushed thermal liner improves warmth but reduces dexterity and increases carton volume. A standard 13-gauge nitrile glove may pack 120 pairs per export carton around 52 x 28 x 38 cm. A thermal full-dip version may pack only 60 pairs per carton, sometimes 72 pairs if compressed. That matters for LCL freight and warehouse space, not just unit price.
Testing Must Follow the Exact Glove
EN ISO 374 results are not transferable across similar-looking gloves. A change from 0.8 mm to 1.0 mm coating, a different curing temperature, a new plasticiser or a switch from nitrile to nitrile-PVC blend can change breakthrough time. EN ISO 374-1:2016+A1:2018 uses Type A, Type B or Type C classification based on permeation against listed test chemicals. EN ISO 374-5:2016 covers micro-organism risks. Jet A-1 and diesel are not simple catalogue checkboxes under the EN 374 letter-code system, so buyers often need additional permeation testing using a named fuel and a method such as ASTM F739. For factory control, chemical performance is not proven by final carton inspection. It is controlled by approved compound, coating weight, dipping depth, oven cure profile and retained batch samples. On a nitrile coated glove, we would normally lock the liner yarn, gauge, mould size set, compound recipe, dip sequence and target coating weight before bulk production. If the customer wants a different blue coating after approval, that is not just a colour change; pigment and viscosity can affect dipping. Packaging should only claim what the report supports. We can print EN 388 pictograms, CE information and customer branding when the glove has valid test data and the technical file route is agreed. For private-label work gloves, our normal inspection can use AQL 2.5 for major defects and AQL 4.0 for minor appearance defects. That catches holes, wrong size marks, poor printing and packing errors. It does not replace EN ISO 374 permeation testing.
MOQ, Lead Time and Buying Advice
For fuel handling gloves based on an existing 13-gauge liner and standard nitrile coating, realistic MOQ is usually 3,000 pairs per size mix in black, grey or blue. A custom liner colour, conductive yarn, special cuff label, retail header card or non-standard sandy texture normally pushes the practical MOQ to 5,000 to 10,000 pairs. Size runs matter: if the order is split across sizes 7 to 11, each size still needs enough volume to run cleanly on the dipping line. Sampling is not instant. A simple adjustment on an existing mould set may take 10 to 14 days. Conductive yarn, thermal liner or a new coating compound usually takes 2 to 3 weeks for workable samples. Third-party EN 388 or EN 16350 testing can add around 2 to 4 weeks depending on lab queue. EN ISO 374 or ASTM F739 testing against named fuels can add 3 to 6 weeks, sometimes longer if the lab asks for extra samples or a defined challenge chemical. Bulk production is commonly 35 to 50 days after sample approval, packaging artwork and deposit. FOB Ningbo or Shanghai is usually cleaner than DDP for chemical PPE because import compliance, user instructions and local PPE registration remain the buyer responsibility. For container planning, coated gloves vary widely, but a 20 ft container may hold roughly 1,200 to 1,600 export cartons depending on carton size and weight limits. Thermal or gauntlet gloves reduce that number quickly. Do not buy fuel handling gloves from a photo and a low unit price. Ask for liner material, gauge, coating type, coating coverage, cuff length, EN 388 result, EN 16350 data if anti-static is required, and whether any EN ISO 374 report belongs to the exact glove code. GloveMark is a good fit for OEM nitrile or PVC work gloves for hose handling, diesel maintenance and airport ground support. If the job is certified immersion protection against named fuels, we will build to a test plan with a lab or tell you plainly that it belongs with a specialist chemical glove producer.
