A chemical-resistant spray head with a 28\/400 thread and an infinitely adjustable nozzle from pinpoint jet to fine mist.

The nozzle adjusts steplessly between a pinpoint jet and a fine mist, with a mid-range stroke of 1.2 ml per spray. That makes it the go-to head for 1,000 ml HDPE cylinder bottles, the ones detailers use to bottle up their own cleaners, quick detailers and sealants.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_hero.jpg?v=1776204868\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon on a workbench by a porsche gt3 rs loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStepless nozzle from jet to mist.\u003c\/strong\u003e One twist of the head switches between a focused jet for wheels and bug splatter and a fine aerosol for finish sprays or plastic care.

With typical detailing use, one bottle lasts 30 to 40 spray bursts across the whole car.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical-resistant internals.\u003c\/strong\u003e The spring, valve and seal are built for surfactants, IPA-based solvents and mildly alkaline APC cleaners. Cheap discount spray heads lose spring tension after two or three weeks with aggressive cleaners — that's just not the CHS-3AN's problem.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003cblockquote class=\"praxistipp\"\u003e\n  \u003cp\u003e\u003cstrong\u003eDetailing1's tip from the shop:\u003c\/strong\u003e The most common mix-up is the thread. 28\/400 and 28\/410 look identical, but they only seal properly on the matching bottles. The Canyon CHS-3AN spray head goes on our 1,000 ml HDPE cylinder bottle and on any third-party bottle with a 28\/400 neck. For the original 500 and 750 ml Koch-Chemie bottles you need the \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-opus-28-410\"\u003eOpus spray head\u003c\/a\u003e with a 28\/410 thread. The wrong thread means: it sits crooked, doesn't seal, pulls air and atomises unevenly.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTwist it stepless. Lock it for continuous spraying.\u003c\/h3\u003e\n\u003cp\u003eThe Canyon CHS-3AN spray head works with a twist head that has four main positions: OFF (closed), Stream (pinpoint jet), Spray (mist) and the smooth in-between stages. The \"Stream\" setting delivers a concentrated jet with reach out to about 40 cm — perfect for the gaps between wheel spokes or targeted bug pre-treatment on the bonnet. In \"Spray\" mode the nozzle atomises into a fine aerosol that lays down evenly at about 25–30 cm.\u003c\/p\u003e\n\n\u003cp\u003eFor continuous spraying during a foam wash or a wide quick-detailer pass, the CHS-3AN has a lock on the trigger. You pull the trigger all the way and push the little plastic tab forward — the spray head then stays open without you having to hold it. That saves your wrist on bigger cars and makes laying product down on estate roofs or SUV side panels far more relaxed.\u003c\/p\u003e\n\n\u003cp\u003eThe piston mechanism is built as a so-called \"ring-lip piston\" — that's Canyon's term for a sealing lip that gives under pressure and seals cleanly on the return stroke. In practice that means: even after 2,000 to 3,000 spray bursts the stroke stays constant at 1.2 ml, as long as you haven't clogged the head with chemistry left to dry inside.\u003c\/p\u003e\n\n\u003cp\u003eWorking clean means setting the nozzle to OFF after every job and, with aggressive cleaners, pulling some clean water through. Otherwise surfactants and waxes dry in the inner channel and block the valve within a few days. Ignore that and you swap a 4-euro spray head every three months instead of every two years — that's by far the most common reason spray heads fail early.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_anwendung.jpg?v=1776204868\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon in use on a vehicle loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\n\u003ch3\u003eFits 28\/400. Not 28\/410.\u003c\/h3\u003e\n\u003cp\u003eThe CHS-3AN fits any bottle with a 28\/400 thread — the European standard for 1,000 ml HDPE cylinder bottles in the detailing world. That includes our \u003ca href=\"\/en\/products\/koch-chemie-hdpe-zylinderflasche-28-400-spruehflasche-1000ml\"\u003eHDPE cylinder bottle 28\/400\u003c\/a\u003e, the CarPro Dilute bottles and most neutral empties from detailing wholesale.\u003c\/p\u003e\n\n\u003cp\u003eThe number \"28\/400\" tells you two things: the neck outer diameter (28 mm) and the thread type to SPI standard (400 = a shallow thread with 6.3 turns per inch). The 28\/410 thread is almost identical in diameter but has a different flank geometry. You can barely see the difference — but you can measure it: a 28\/410 spray head on a 28\/400 bottle sits crooked and only seals on one side.\u003c\/p\u003e\n\n\u003cp\u003eThis spray head doesn't fit the original 500 ml and 750 ml Koch-Chemie bottles — those carry a 28\/410 thread and come with their spray head fitted from the factory. For 28\/400 bottles the Canyon CHS-3AN spray head is the right part, but it's no replacement for high-pressure pump sprayers like an iK Multi 3 or iK Foam Pro 2. The output is enough for manual detailing, not for active pressure build-up or foam generation.\u003c\/p\u003e\n\n\u003cp\u003eIf you often switch between spraying overhead and the normal spray direction, take a look at the \u003ca href=\"\/en\/products\/ik-sprayers-spruehkopf-ik-trigger-multi-tr-1-360-canyon-chs3an\"\u003eiK Trigger 360°\u003c\/a\u003e from the same Canyon family. It sprays upside down too — handy for wheel-arch cleaning or in tight engine-bay corners — has the same 28\/400 fitting, but costs a euro more per unit and about five euros more in a five-pack.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_detail.jpg?v=1776204868\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon spray close up loading=\"lazy\"\u003e\u003c\/p\u003e\n\n\n\u003ch3\u003eYour workhorse for bottling your own cleaners\u003c\/h3\u003e\n\u003cp\u003eThe Canyon CHS-3AN spray head is the right call when you dilute concentrates like Green Star, Pol Star or Finish Spray Exterior yourself and work out of the 1,000 ml spray bottle. For workshops and detailers running several bottles in parallel, it pays to buy it as a spare — a second spray head costs less than a new bottle plus head.\u003c\/p\u003e\n\n\u003cp\u003eIt's less suited if you only buy ready-made spray products from Koch-Chemie, since those come with the Opus spray head already fitted. It has no place on a 5-litre canister either — there a pump or pressure sprayer does the work. Also off-limits: strongly acidic wheel cleaners like the Koch-Chemie Felgenreiniger Säure (Rrp). The CHS-3AN's acid resistance ends at pH values around 2.5 — anything below that attacks the seals within a few weeks.\u003c\/p\u003e\n\n\u003cp\u003eIf you're starting from scratch, go straight for the \u003ca href=\"\/en\/products\/koch-chemie-spruehkopf-spruehflasche-set\"\u003espray head + 1,000 ml HDPE bottle set\u003c\/a\u003e. The set costs 7.49 euros against 7.98 euros for the separate parts — two fewer lines in the cart and a bottle that seals perfectly straight from the factory. For labelling your own decants, grab a waterproof industrial marker or a pre-printed label: contents, dilution, fill date. An unlabelled spray bottle of diluted APC next to one of diluted glass cleaner is the classic among detailer mix-ups — and exactly why pros label every bottle.\u003c\/p\u003e\n\n\u003cp\u003eThe Detailing1 insight to close: if you're honest about it, you don't swap the Canyon CHS-3AN spray head because it breaks, but because of contamination. A spray head that ran APC for years can never be fully switched over to glass cleaner — microscopic surfactant residue in the inner channel foams the glass cleaner up and leaves streaks. The fix is a fixed assignment: one spray head per product type.\u003c\/p\u003e\n\n\u003cp\u003eIn the shop you mark the trigger straight away with a dot of paint marker. Green for glass cleaner, red for APC, blue for quick detailer, yellow for IPA wipe-downs. Four heads, four bottles, no mix-up — and each head then lasts its two to three years too, because it runs constant chemistry instead of seeing different surfactants every week.\u003c\/p\u003e\n\n\u003cp\u003eDurability in numbers: with daily pro use and proper care (a water flush after the shift, OFF position for storage) the Canyon CHS-3AN spray head averages 18,000 to 25,000 spray bursts. At a 1.2 ml stroke that works out to about 25 to 30 fully emptied 1,000 ml bottles before valve tension or the sealing lip noticeably fade. Hobby detailers in practice never swap the head for wear — only for contamination or a misplaced bottle.\u003c\/p\u003e\n\n\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/d1_koch-chemie-spruehkopf-star-canyon-chs-3an_closeup.jpg?v=1776204869\" alt=\"Koch-Chemie spray head \" star chs-3an by canyon in hand workshop loading=\"lazy\"\u003e\u003c\/p\u003e\n\n","brand":"Koch-Chemie","offers":[{"title":"Default Title","offer_id":48488820212047,"sku":"D1-KCX-999001","price":8.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/3272\/7375\/files\/koch-chemie-spruehkopf-star-chs-3an-canyon.png?v=1722941263","url":"https:\/\/detailing1depot.com\/en\/products\/koch-chemie-spruehkopf-star-canyon-chs-3an","provider":"Detailing1","version":"1.0","type":"link"}
