Factory-level comparison of 13-gauge and 15-gauge PU coated gloves, covering liner yarn, PU dipping behaviour, abrasion wear, MOQ, price drivers, packing, AQL inspection, Incoterms and RFQ wording for B2B glove buyers.
The Short Answer for Buyers
13G PU is the safer cost-control choice for dry packing, carton handling, inspection and general assembly. 15G PU is the better dexterity choice when workers handle M3-M5 screws, small clips, wire terminals, PCB parts or moulded plastic components. The gauge difference is felt at the fingertip first: 13G gives more liner body, while 15G sits closer to the finger and shows small defects faster. We do not recommend paying for HPPE, aramid or stainless-steel blended yarn unless the buyer has a real EN 388:2016+A1:2018 or ANSI/ISEA 105 cut requirement. For OEM bulk, a workable MOQ is usually 3,000-5,000 pairs per colour per style, with a practical size run such as 7-10 or 6-11. Sampling for a plain white 13G polyester PU glove can normally be 5-7 working days if yarn and PU resin are in stock. A 15G nylon-spandex version usually needs 7-10 working days because finger length, cuff recovery and dip-line consistency need tighter adjustment. We do not treat 500 pairs split across six colours with retail packaging, EAN labels and mixed cartons as a factory-efficient production order.
What Gauge Actually Changes
Gauge is the number of knitting needles per inch on the glove knitting machine. A 13G liner uses a coarser needle bed than a 15G liner, so it normally uses a thicker yarn and gives a fuller feel in the palm and fingertips. A 15G liner uses finer yarn, produces a smoother surface and gives better finger definition, especially around the sidewalls and thumb crotch. The main yarn choices are polyester, nylon and nylon-spandex. Polyester is the usual price-control option for 13G PU gloves. Nylon gives a smoother hand feel and better recovery after stretching. A 15G nylon liner with 3-5 percent spandex can improve fit, but it can also feel tight during an 8-10 hour shift, especially for workers with wide palms or when the size split is too narrow. Gauge does not equal protection level. A 15G polyester PU glove is still a light-duty dry-handling glove unless the liner contains a cut-resistant yarn and has a valid test report. If cut risk matters, the RFQ should state the target standard, such as EN 388:2016+A1:2018 with a TDM cut letter under EN ISO 13997, or ANSI/ISEA 105 cut level A1-A9. For ordinary PU gloves, many buyers ask for abrasion, blade cut, tear and puncture data under EN 388, but the exact rating must come from the tested construction, not from the gauge number. Fit complaints also change by gauge. 13G is more tolerant when one glove needs to suit many workers. 15G gives a neater fit, but wrong sizing is more obvious: fingertips can feel short, the cuff can feel tight, and the palm can twist if the liner is not knitted evenly.
PU Coating Behaviour on 13G and 15G Liners
PU means polyurethane. On palm-coated gloves it is a thin dry-grip coating, normally used for low-lint handling, clean part control and light abrasion resistance. It is not an oil-grip coating and it is not chemical protection. If the job involves oily machined parts, micro-foam nitrile or sandy nitrile is usually a better discussion. If there is detergent, acid, solvent or cleaning chemical exposure, the buyer should move to a glove tested to EN ISO 374-1:2016, not a PU palm glove. The production route is straightforward but the control points matter: knit liner, check loose yarn, overlock cuff, turn where required, load onto hand formers, apply coagulant, dip PU, level the coating, oven cure, cool, strip, pair, inspect and pack. We do not quote one universal curing temperature because PU resin, glove weight, line speed and oven length all affect the setting. What we check is the finished result: no tacky palm, no cracked PU film, no hard fingertip, no exposed liner at the working fingertips and no heavy yellowing on white PU. 13G liners have a more open knit, so PU can sit deeper into the surface and look slightly heavier. This can be useful for general handling, but too much penetration makes the glove stiffer. 15G liners have a finer face, so the coating often looks cleaner and flatter. The weak point is visibility of defects: pinholes, dirty fibre specks, uneven fingertips, wavy dip lines and hard thumb crotches show up quickly, especially on white liner with white PU. Colour matters. White PU on white polyester is the least forgiving because dust, scorch marks and fibre contamination are visible. Grey or black PU hides cosmetic variation better, but the buyer still needs to approve grip feel, coating coverage and colour shade before bulk.
Cost, Wear Life and Where the Saving Hides
The price gap between 13G and 15G comes from more than yarn weight. A 13G polyester PU glove runs on common machines, knits faster, tolerates small size variation better and normally has fewer visible cosmetic rejects. A 15G nylon-spandex PU glove uses finer yarn, can knit more slowly and needs stricter control of finger length, cuff tension and dip-line position. As a practical FOB China reference, plain 13G polyester PU belongs in the low-cost industrial band. 15G nylon or nylon-spandex PU sits higher before adding cuff printing, retail packaging, test reports, palletisation or third-party inspection. Quotations should use current polyester yarn, nylon yarn, PU resin, labour and RMB/USD exchange cost. We do not promise a fixed annual price unless the buyer agrees the validity period, order quantity and raw material basis. Wear life depends on the surface, not just the gauge. On cardboard, plastic totes, painted parts, aluminium profiles and electronics benches, 15G PU can perform well because the coating is continuous and workers value the feel. On stamped metal, carton staples, burrs, rough timber, steel strapping or concrete blocks, the thinner liner usually fails earlier at the fingertip or thumb web. EN 388 abrasion level 3 or 4 is useful lab information, but it does not fully predict a worker pinching sharp edges for a full shift. The hidden saving with 13G is lower complaint risk. It is easier to keep fit, coating appearance and packing stable across repeat orders. A common export pack is 12 pairs per inner bag and 120 pairs per master carton. Carton size depends on gauge, cuff length, size ratio and compression. PU gloves are compact compared with leather, winter or impact gloves, so sea freight usually does not decide the 13G versus 15G choice under FOB Ningbo or FOB Shanghai. User acceptance and AQL results matter more.
Branding and Packaging Choices
The cleanest OEM branding for 13G and 15G PU gloves is a printed cuff logo, size-coloured overlock, size mark, carton mark, printed polybag or header card. We avoid large logos on the PU working surface. Ink on the palm can reduce grip, crack during use and fail a simple dry rub check. A woven cuff label is possible, but for a low-cost PU glove the label may cost too much relative to the glove. White, grey and black are the easiest liner and coating colours because yarn and PU resin are commonly available. Pantone-matched cuffs, coloured PU palms and two-colour liners need more control. That sample should confirm gauge, yarn, coating colour, cuff overlock, size mark, logo position, polybag artwork, carton label, barcode and inner pack quantity. Lead time depends on packaging as much as knitting. A plain bulk order can often ship in about 4-6 weeks after deposit and approved sample when capacity is open. Printed polybags, hang tags, EAN barcodes, inner boxes, retail cartons and customer carton labels can add 1-2 weeks, especially when artwork arrives late or barcodes are not verified. For inspection, many B2B buyers use AQL 2.5 for major defects and AQL 4.0 for minor defects. Major issues include wrong material, wrong size marking, exposed liner at working fingertips, tacky coating, wrong carton quantity or missing required label. Minor issues include loose threads, light shade variation, small print misalignment or slight cuff overlock inconsistency. A capable supplier may be able to pack loose cartons or pallets. Pallets reduce carton damage and speed unloading, but they reduce container cube utilisation.
How to Specify the Right One in an RFQ
A useful RFQ needs more than 13 gauge vs 15 gauge PU gloves, good quality. For a 13G cost option, write: 13-gauge polyester liner, white PU palm coating, knitted wrist, sizes 7-10, size-coloured overlock, 12 pairs per inner bag, 120 pairs per carton, EN 388:2016+A1:2018 report required if available, inspection to AQL 2.5 major and 4.0 minor, Incoterm FOB Ningbo or FOB Shanghai. For a 15G dexterity option, write: 15-gauge nylon or nylon-spandex liner, grey PU palm coating, snug fit, sizes 6-11, even fingertip coating, no tacky palm, no exposed liner at fingertips, printed cuff logo, individual polybag optional, carton label with SKU, size, quantity, gross weight and net weight. If the glove will be sold into the EU or UK, state whether CE or UKCA documentation is required and who will hold the technical file. Ask for both samples if the end user is undecided. Two or three size sets by courier cost much less than correcting the wrong hand feel after a full PO. When comparing samples, test actual tasks: picking screws, opening cartons, handling oily parts, rubbing against a stamped edge, checking touch-screen use if required and wearing the glove for at least half a shift. For freight, give the destination port, delivery address, pallet requirement and carton weight limit before asking for CIF or DDP. A 20 ft container can carry a large quantity of PU gloves, but the final pair count depends on carton dimensions, size ratio, compression, inner packing and pallets. Loose cartons load more pairs; pallets protect cartons better. Our recommendation is direct. Choose 13G PU for cost-controlled dry assembly, packing, inspection and general issue. Choose 15G PU when fingertip feel and small-part handling justify the higher unit cost. If the risk is oil, wet grip, chemical splash, heat contact or real cut exposure, do not solve it by moving from 13G to 15G. Change the coating, yarn or glove type, then test against EN 388, EN ISO 374, EN 407 or ANSI/ISEA 105 before bulk production.
