In a recirculating system it can drain the tank low enough to leave roots dry. Silicone and tape rarely last on flexible plastic; a correctly sized grommet in a clean hole seals tight for the life of the system, keeping the reservoir level steady and plants growing evenly.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasure:\u003c\/strong\u003e check the grommet body and drill a test hole in an offcut first – it should be a snug push fit, not loose.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill:\u003c\/strong\u003e use a hole saw or step drill and remove any burr so the edge cannot cut the grommet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e push the grommet in from the outside so the flange sits flat against the wall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert the fitting:\u003c\/strong\u003e wet the barb or pipe with clean water and push it through with a twisting action.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTest:\u003c\/strong\u003e fill the container above the hole and check for drips before connecting the pump.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Antelco (made in Australia)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e top hat (flanged) grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e 13mm, 19mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuits:\u003c\/strong\u003e 13mm or 19mm barbed fittings and irrigation pipe, by size\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e flexible rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 100 grommets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole size:\u003c\/strong\u003e not published by the maker – measure the grommet body before drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Antelco","offers":[{"title":"13mm","offer_id":53803792335114,"sku":"HYD-ANTE-006-01","price":43.8,"currency_code":"GBP","in_stock":true},{"title":"19mm","offer_id":53803792367882,"sku":"HYD-ANTE-006-02","price":55.3,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/antelco-top-hat-grommets-13mm-1.jpg?v=1790229310","url":"https:\/\/hydrocropshop.co.uk\/products\/antelco-top-hat-grommets","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
