It carries the model number 1J0 612 041 GS and is made from iron with a black finish. The valve forms part of the engine vacuum system, where it helps control the direction of vacuum flow. If your original valve has failed, this part offers a like-for-like replacement. The package includes one check valve vacuum tube. No other fittings or hardware are supplied. Before ordering, check the model number against your existing part to confirm it is the correct item for your vehicle.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black iron check valve vacuum tube, model 1J0 612 041 GS, for Volkswagen and Skoda\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/3433\/2025-10-16\/original-image\/300f5665-5876-4879-9bd3-13842cdc17a7.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe check valve is built around a simple iron body. This material is commonly used in automotive vacuum components because it can withstand the under-bonnet environment. The black finish gives the part a neat appearance that blends with typical engine bay fittings. The unit is designed to fit specific Volkswagen and Skoda models, so the model number is the key detail to verify.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe valve is made from iron. This gives the component a solid metal construction rather than a plastic body. Iron is a practical choice for a vacuum valve because it holds its shape and can tolerate the heat and vibration found in an engine bay. The black coating covers the exterior. There are no other materials listed for this part. The build is focused on function: a one-piece valve body that connects into the vacuum line.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eNo dimensions are provided for this check valve vacuum tube. The fit is determined by the model number 1J0 612 041 GS and the listed vehicle applications. Because the part is designed for Volkswagen and Skoda, it should match the original mounting points and hose connections. If you are unsure about compatibility, compare the model number with the part currently fitted to your vehicle. The compact size allows it to sit within the existing vacuum pipework without modification.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black iron check valve vacuum tube, model 1J0 612 041 GS, for Volkswagen and Skoda\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/3433\/2025-10-16\/original-image\/84a0e168-3081-42ba-8f05-71dba7ed34c9.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis vacuum check valve is used in the engine management and emissions systems of compatible vehicles. It allows vacuum to flow in one direction and prevents backflow, which helps maintain stable vacuum pressure for components such as the brake servo, turbo actuator, or emissions control valves. It is a service part, not a performance upgrade.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eIn a professional workshop, this check valve would be fitted as part of a diagnostic repair. If a vacuum leak or failed non-return valve is found, replacing it with the correct model number restores the system to its original operation. Mechanics can identify the part by the 1J0 612 041 GS code. It is suitable for routine maintenance and repair work on Volkswagen and Skoda vehicles where this part number is specified.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor a competent home mechanic, this valve can be fitted with basic hand tools if the vehicle is safely raised and supported. It is not a universal part, so it should only be used on vehicles that list 1J0 612 041 GS as compatible. The iron body and black finish are consistent with the original component. If you are not confident working on vacuum systems, have the part installed by a garage.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black iron check valve vacuum tube, model 1J0 612 041 GS, for Volkswagen and Skoda\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/3433\/2025-10-16\/original-image\/92cd96ce-a249-4358-8ae3-9486dbce4d2e.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe main value of this part is that it provides a specific replacement for a known model number. It avoids the need to modify or adapt a different valve. Because it is a single iron component, there are no separate seals or clips to lose. The part is simple to identify and order when you have the correct reference.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThis is not a reusable or serviceable item; it is a replacement valve. Once fitted, it requires no routine maintenance beyond checking that the vacuum connections remain secure. The iron construction does not need special care. If the valve fails again, it should be replaced with the same model number. There are no user-serviceable parts inside.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eChoose this check valve vacuum tube if your vehicle requires part number 1J0 612 041 GS and the original valve has stopped working. It is made from iron with a black finish and is supplied as a single unit. The listing is fact-based: no performance gains are claimed, and no dimensions are given. The part is intended to restore standard vacuum operation on compatible Volkswagen and Skoda models. Always confirm the model number before buying.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black iron check valve vacuum tube, model 1J0 612 041 GS, for Volkswagen and Skoda\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/3433\/2025-10-16\/original-image\/9cd33a94-eead-43ce-a52c-e9525be6d82a.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black iron check valve vacuum tube, model 1J0 612 041 GS, for Volkswagen and Skoda\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/3433\/2025-10-16\/original-image\/9f1b7853-304c-4873-ad6f-bfdd7421bea7.webp\"\u003e\u003c\/div\u003e","brand":"u9cmuw-dx","offers":[{"title":"Black","offer_id":58098105221500,"sku":"CJQT216393801AZ","price":25.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/1685\/3628\/files\/022675e2-9cc8-4244-818f-cc9d851db593.webp?v=1793616840","url":"https:\/\/havenmere.co.uk\/products\/check-valve-vacuum-tube-for-volkswagen-skoda-iron-non-return-valve-model-1j0-612-041-gs-black-automotive-engine-vacuum-hose-check-valve","provider":"Havenmere.co.uk","version":"1.0","type":"link"}
