Compared to latex, silicone is odor-free and more resistant to algae buildup on the inner wall. It is a common choice for both freshwater and saltwater aquarium air and water lines.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/details\u003e\n\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-cta\"\u003e\n    🛒 Select your \u003cstrong\u003eID × OD size and length\u003c\/strong\u003e above, then add to cart — ships from our US warehouse.\n  \u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"3x5mm \/ 1M","offer_id":52332953567506,"sku":"WZYKKMX0658x1","price":2.39,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 1M","offer_id":52332953600274,"sku":"WZYKKMX0659x1","price":3.03,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 1M","offer_id":52332953633042,"sku":"WZYKKMX0660x1","price":3.66,"currency_code":"USD","in_stock":true},{"title":"3x5mm \/ 2M","offer_id":52332953665810,"sku":"WZYKKMX0658x2","price":3.03,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 2M","offer_id":52332953698578,"sku":"WZYKKMX0659x2","price":5.25,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 2M","offer_id":52332953731346,"sku":"WZYKKMX0660x2","price":6.51,"currency_code":"USD","in_stock":true},{"title":"3x5mm \/ 5M","offer_id":52332953764114,"sku":"WZYKKMX0658x5","price":5.89,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 5M","offer_id":52332953796882,"sku":"WZYKKMX0659x5","price":11.9,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 5M","offer_id":52332953829650,"sku":"WZYKKMX0660x5","price":15.07,"currency_code":"USD","in_stock":true},{"title":"3x5mm \/ 10M","offer_id":52332953862418,"sku":"WZYKKMX0658x10","price":10.95,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 10M","offer_id":52332953895186,"sku":"WZYKKMX0659x10","price":23.02,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 10M","offer_id":52332953927954,"sku":"WZYKKMX0660x10","price":29.35,"currency_code":"USD","in_stock":true},{"title":"3x5mm \/ 20M","offer_id":52332953960722,"sku":"WZYKKMX0658x20","price":21.12,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 20M","offer_id":52332953993490,"sku":"WZYKKMX0659x20","price":45.22,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 20M","offer_id":52332954026258,"sku":"WZYKKMX0660x20","price":57.91,"currency_code":"USD","in_stock":true},{"title":"3x5mm \/ 30M","offer_id":52332954059026,"sku":"WZYKKMX0658x30","price":31.25,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 30M","offer_id":52332954091794,"sku":"WZYKKMX0659x30","price":67.4,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 30M","offer_id":52332954124562,"sku":"WZYKKMX0660x30","price":86.44,"currency_code":"USD","in_stock":true},{"title":"3x5mm \/ 50M","offer_id":52332954157330,"sku":"WZYKKMX0658x50","price":51.54,"currency_code":"USD","in_stock":true},{"title":"5x8mm \/ 50M","offer_id":52332954190098,"sku":"WZYKKMX0659x50","price":111.83,"currency_code":"USD","in_stock":true},{"title":"7x10mm \/ 50M","offer_id":52332954222866,"sku":"WZYKKMX0660x50","price":143.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Picture5of7_8028063f-c636-40d0-9324-e6c352fc92dd.jpg?v=1781189053","url":"https:\/\/homediyer.com\/de\/products\/clear-silicone-tube-food-grade-flexible-hose","provider":"HomeDIYer","version":"1.0","type":"link"}
