{"product_id":"creality-sparkx-i7-hot-end-sock-pack-of-3","title":"Creality SPARKX i7 Hot End Sock, Pack of 3","description":"\u003cdiv class=\"product-description\"\u003e\n\n\u003cp\u003eYour SPARKX i7 has been printing every evening for months. Then the first layers start looking uneven, a blob of PETG welds itself to the heater, and the nozzle temperature on the screen drifts a few degrees every time the part cooling fan spins up. Look closely at the toolhead and you will often find the cause: a torn, hardened or filament-caked silicone sock.\u003c\/p\u003e\n\u003cp\u003eThis genuine Creality pack gives you three replacement socks shaped for the SPARKX i7 hotend, so you can swap a damaged one in a minute and keep two on the shelf.\u003c\/p\u003e\n\u003cp\u003eThe result is a stable nozzle temperature, a cleaner hotend and fewer failed prints.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGenuine Creality Part 4004010305 | Pack of 3 Socks | Moulded for the SPARKX i7 Hotend | Rated to 300°C | Flame-Retardant Silicone | Tool-Free Fitting | Fits i7, i7 Autofill and Colour Combo\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch2\u003eWho the SPARKX i7 hot end sock is built for\u003c\/h2\u003e\n\n\u003ch3\u003eHome users and hobbyist Makers\u003c\/h3\u003e\n\u003cp\u003eThe \u003ca href=\"https:\/\/3dprintingstore.co.za\/products\/creality-sparkx-i7-3d-printer-with-cfs-lite-4-filament-dispenser\"\u003eCreality SparkX i7 3D Printer with CFS Lite 4 Filament Dispenser\u003c\/a\u003e is built for people who want to print, not tinker. A worn sock is one of the few parts you will replace regularly, and this pack covers that for a long time. Fit a fresh sock before a four-colour gift set of planters or a stack of TPU phone cases, and the hotend holds temperature for the whole job.\u003c\/p\u003e\n\n\u003ch3\u003eSchools and classrooms\u003c\/h3\u003e\n\u003cp\u003eLearners load filament, clear jams and bump toolheads, and socks take the knocks. Three spares in the drawer mean a teacher can fix a torn sock between periods without ordering parts or taking the printer offline. A class can finish its batch of PLA name plates or simple engineering brackets on schedule, even if one sock gets damaged mid-term.\u003c\/p\u003e\n\n\u003ch3\u003eSmall print businesses\u003c\/h3\u003e\n\u003cp\u003eIf you sell printed products, every failed print costs filament and time. Running several i7 printers at up to 500 mm\/s puts sustained heat and fan airflow across the hotend all day. Replacing socks on a schedule, rather than waiting for one to split, keeps first layers consistent across the farm. A run of 50 PETG cable organisers comes off the plate with the same surface finish on the last part as the first.\u003c\/p\u003e\n\n\u003ch2\u003eWhat sets the SPARKX i7 hot end sock apart\u003c\/h2\u003e\n\n\u003ch3\u003eTemperature that stays where you set it\u003c\/h3\u003e\n\u003cp\u003eThe SPARKX i7 cools prints hard to reach high speeds, and that airflow also hits the hotend. Without insulation, the heater has to keep correcting, and the reading from the \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Thermistor\"\u003ethermistor\u003c\/a\u003e swings by a few degrees. This sock wraps the heater and blocks that draft, so the controller holds a steady temperature with less effort. A stable melt zone gives you consistent extrusion, cleaner layer lines and fewer under-extruded patches on fast perimeters. Some retailers also note that a well-fitted sock reduces the risk of temperature fault errors during high-speed printing.\u003c\/p\u003e\n\n\u003ch3\u003eMade for the SPARKX i7, not adapted from another printer\u003c\/h3\u003e\n\u003cp\u003eGeneric socks for MK8 or V6 style blocks will not seat on the i7 toolhead. This genuine Creality part, number 4004010305, is moulded to the shape of the SPARKX i7 hotend, with a notch that aligns with the nozzle and openings for the wiring. It sits flush, so it does not rub the print or catch on the front cover. That precise fit is what lets it insulate properly instead of hanging loose and letting airflow through the gaps.\u003c\/p\u003e\n\n\u003ch3\u003eFilament wipes off instead of baking on\u003c\/h3\u003e\n\u003cp\u003eOoze and blobs land on the hotend during every colour change and every failed first layer. On bare metal, that plastic carbonises and builds up into a crust that eventually drops onto your print. \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Silicone\"\u003eSilicone\u003c\/a\u003e resists sticking, so most residue peels off once it cools. The material is flame-retardant and rated for continuous use up to 300°C, matching the SPARKX i7's maximum nozzle temperature, so it handles PLA, PETG, PLA-CF and TPU without softening or degrading at normal printing temperatures.\u003c\/p\u003e\n\n\u003ch3\u003eThree socks, one minute each to fit\u003c\/h3\u003e\n\u003cp\u003eLike every consumable in \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Fused_filament_fabrication\"\u003efused filament fabrication\u003c\/a\u003e, socks wear out. Repeated heating cycles harden the silicone, and clumsy nozzle cleaning can tear it. Buying a pack of three means you always have a spare ready when that happens. Fitting is tool-free: remove the toolhead front cover, pinch the old sock and pull it outwards and downwards, then align the new sock's notch with the nozzle and push it in at an angle. Refit the cover and you are printing again within minutes.\u003c\/p\u003e\n\n\u003ch2\u003eFull specifications: SPARKX i7 hot end sock\u003c\/h2\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 6px; text-align: left;\"\u003eSpec\u003c\/th\u003e\n\u003cth style=\"padding: 6px; text-align: left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eGeneral\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCreality\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eProduct\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eSPARKX i7 Hot End Sock (silicone sock), pack of 3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eStore SKU\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCRE794\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eManufacturer part number\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e4004010305\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eEAN\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e6977726812436\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eMaterial and performance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eFlame-retardant silicone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eColour\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eMatte black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eMaximum continuous temperature\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e300°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eFit\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eMoulded to the SPARKX i7 hotend, nozzle notch and wiring openings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eTool-free push fit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003ePrinters\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCreality SPARKX i7, SPARKX i7 Autofill, SPARKX i7 Colour Combo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eNot compatible with\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCreality K2 series, K1 series, Ender-3 series hotends\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eHost printer reference (SPARKX i7)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eMaximum nozzle temperature\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e300°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eMaximum print speed\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e500 mm\/s\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eSupported filaments\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003ePLA, PETG, PLA-CF, TPU (64D and harder)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eIn the box\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003ePackage contents\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e3 × SPARKX i7 silicone hot end socks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eOrdering, shipping and support for SPARKX i7 hot end socks\u003c\/h2\u003e\n\u003cp\u003eWe courier SPARKX i7 hot end socks to any address in South Africa, or you can collect from our Centurion or Boksburg store.

Creality's own guide says you can use a spanner to gently lever it off if it resists.
