It is the part you reach for when you add another DWC pot, a second airstone in a reservoir or a spur off an irrigation run, and it saves buying a bigger pump when the existing one has capacity to spare. Moulded from \u003cstrong\u003erigid plastic\u003c\/strong\u003e, it pushes on firmly and holds a leak-free seal under continuous pump pressure. Small, cheap and worth keeping a handful of in the drawer.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne in, two out\u003c\/strong\u003e - Branch a single air line to feed two stones or pots.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits 4mm tubing\u003c\/strong\u003e - Standard bore used across air pumps, DWC and aquarium kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRigid plastic build\u003c\/strong\u003e - Holds its shape and its seal under constant pressure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo tools needed\u003c\/strong\u003e - Push-on fit, so reconfiguring a system takes seconds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpand cheaply\u003c\/strong\u003e - Grow a system without upgrading the pump.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eThe Problem with One Airline and Two Tanks\u003c\/h3\u003e\u003cp\u003eAir pumps almost always have more output than a single stone can use, but the outlet count is fixed. Growers end up running a second pump, or worse, moving one stone between reservoirs and leaving the other going stale. Dissolved oxygen falls, root zones turn sluggish and root rot gets its opening. A tee piece splits the flow you already have and keeps every reservoir aerated around the clock.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCut the airline cleanly where you want the branch to start.\u003c\/li\u003e\n\u003cli\u003ePush both cut ends fully onto two ports of the tee.\u003c\/li\u003e\n\u003cli\u003eRun new tubing from the third port to the extra stone or pot.\u003c\/li\u003e\n\u003cli\u003eFit a non-return valve on each branch if the pump sits below water level.\u003c\/li\u003e\n\u003cli\u003eRun the pump and check every joint for escaping air before walking away.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFitting Size\u003c\/th\u003e\n\u003ctd\u003e4mm airline\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConfiguration\u003c\/th\u003e\n\u003ctd\u003eT-piece, one inlet to two outlets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eRigid moulded plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnection\u003c\/th\u003e\n\u003ctd\u003ePush-fit, no tools required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse\u003c\/th\u003e\n\u003ctd\u003eAir pumps, DWC, aeration and irrigation lines\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Charles Austen","offers":[{"title":"Default Title","offer_id":53446967230730,"sku":null,"price":0.44,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/4mm-airline-tee-piece-1.jpg?v=1785332722","url":"https:\/\/hydrocropshop.co.uk\/products\/4mm-airline-tee-piece","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
