Built from stainless steel and brass components, the injector lets you fine-tune chemical feed with a metering valve while keeping concentrated solutions out of the pump. It includes a siphon hose and a soap spray nozzle sized for effective suction.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the injector feed chemicals without harming my pressure washer?\u003c\/h3\u003e\n\u003cp\u003eThe YAMATIC kit is a downstream design, so cleaning agents are introduced after the pump where pressure is reduced. That prevents corrosive or foaming chemicals from circulating through the pump internals and increases equipment longevity. The construction uses corrosion-resistant metals to withstand frequent use and a broad range of cleaning fluids.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInstalls between the pump outlet and high-pressure hose using 3\/8\" quick connectors.\u003c\/li\u003e\n  \u003cli\u003eChemicals enter only at low-pressure operation (250 PSI or less), protecting pump seals.\u003c\/li\u003e\n  \u003cli\u003eBrass and stainless-steel parts resist chemical degradation for longer service life.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat control do I have over dilution and flow rate?\u003c\/h3\u003e\n\u003cp\u003eAn integrated metering valve gives precise control of the chemical-to-water ratio so you can tailor strength for different surfaces. The valve works across a water flow range of 2 to 5 GPM, letting you go from light rinses to heavier applications without changing equipment. Use the included large-orifice black soap nozzle to maintain the suction needed for consistent chemical feed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable dilution via the metering valve for small or concentrated doses.\u003c\/li\u003e\n  \u003cli\u003eCompatible with 2–5 GPM flow ranges to match most consumer and prosumer washers.\u003c\/li\u003e\n  \u003cli\u003eIncludes large-orifice soap nozzle to ensure proper suction and steady delivery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this kit work with my pressure washer model and temperature range?\u003c\/h3\u003e\n\u003cp\u003eThe injector is rated to a maximum working pressure of 4500 PSI and functions well with most gas-powered washers and many electric units. It handles water temperatures between 32°F and 122°F (0°C–50°C), so it covers common cold and warm-water cleaning tasks. Verify your machine’s outlet is 3\/8\" and that low-pressure chemical injection is supported for best results.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMax working pressure: 4500 PSI for broad compatibility with higher-power washers.\u003c\/li\u003e\n  \u003cli\u003eTemperature tolerance: 32°F–122°F for cold and warm-water applications.\u003c\/li\u003e\n  \u003cli\u003eStandard 3\/8\" quick-connect fittings for easy installation and compatibility.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow easy is it to install and maintain the soap injector?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward: connect the injector between your pump outlet and high-pressure hose using the supplied 3\/8\" quick connectors, attach the siphon tube to your chemical bottle, and select the soap nozzle. Routine maintenance is minimal — rinse the siphon and nozzle after use and inspect fittings for wear. Replacement parts are simple to source due to standard connection sizes and metal components.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-connect assembly fits standard 3\/8\" pressure-washer hookups for fast setup.\u003c\/li\u003e\n  \u003cli\u003eSimple rinsing after each use prevents buildup and prolongs service life.\u003c\/li\u003e\n  \u003cli\u003eDurable metal construction reduces frequency of part replacement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The YAMATIC Adjustable Chemical Injector Kit is aimed at DIY enthusiasts, professional cleaners, and fleet operators who need controlled chemical application without compromising pump health. It’s a good choice when you need adjustable dilution, compatibility with higher-pressure washers, and durable materials for frequent or heavy-duty cleaning tasks. If you plan to use concentrated cleaners, want flexible dosing, and have a 3\/8\" outlet on your pressure washer, this kit provides a reliable, serviceable solution.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use the injector with hot water?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the injector operates from 32°F to 122°F (0°C–50°C), suitable for most warm-water cleaning jobs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What pressure is required for chemical feed?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Chemicals are drawn at low pressure; injector works only when operating at 250 PSI or less for chemical application.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"YAMATIC","offers":[{"title":"Default Title","offer_id":56831830262100,"sku":"B0FL1YLZNN","price":51.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/yamatic-injector-front-assembly.jpg?v=1787020571","url":"https:\/\/gardenluxe.co.uk\/products\/yamatic-adjustable-chemical-injector-kit-for-pressure-washer-3-8-quick-connect-downstream-soap-injector-4500-psi-stainless-br","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
