Push them on, clamp them down, and you've got a watertight joint that won't kink your pipe or trap air. Double-barbed acetal design means they hold fast, even in decent pressure systems. One we recommend constantly for anyone building beyond the stock setup.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e13mm barbed fittings are \u003cstrong\u003epush-fit irrigation connectors\u003c\/strong\u003e designed to join, redirect, and customise 13mm LDPE pipework without requiring tools, glue, or permanent modifications. Made from \u003cstrong\u003eUV-stabilised acetal plastic\u003c\/strong\u003e with a \u003cstrong\u003edouble-barbed design\u003c\/strong\u003e, they create secure, leak-proof connections that handle low to medium pressure systems reliably. Whether you're adding extra pots to an existing layout, splitting flow to multiple zones, or building a hydroponic system from scratch, these fittings give you the flexibility to adapt your irrigation exactly how you need it.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eBarbed fittings sit at the practical end of the connector spectrum.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs Compression fittings:\u003c\/strong\u003e Barbed are cheaper and faster to install; compression are permanent and more rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs Perma-Loc locking systems:\u003c\/strong\u003e Barbed are tool-free and reusable until you seat them properly; Perma-Loc offers a locking nut for on-demand disconnect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs Drip-Lock fittings:\u003c\/strong\u003e Barbed are simpler; Drip-Lock include release collars for easier removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor small to medium systems and DIY builds, barbed fittings are the sweet spot between cost and capability. You get secure connections at a price that doesn't eat into your budget for nutrients or lighting.\u003c\/p\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation basics\u003c\/strong\u003e\u003cbr\u003ePush the 13mm tubing over the barbed fitting until fully seated. For easier installation with cold tubing, warm it in hot water for 10–30 seconds first to soften the material temporarily, then slide it on. The pipe sits flat against the barbs, creating an immediate friction fit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealing the joint\u003c\/strong\u003e\u003cbr\u003eWhen using 13mm LDPE pipe, fit a ratchet clamp at each connection point to lock the joint watertight. The distance between the barbs gives you a flat base for the clamp to grip. This combination of barbed anchor and clamp pressure is what keeps everything airtight.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePressure range and performance\u003c\/strong\u003e\u003cbr\u003eThese fittings handle optimal pressures between 0.5 and 3 bar, making them ideal for micro-irrigation, drip systems, and hydroponic setups. The double-barbed acetal design produces sharper anchoring than standard connectors, meaning better retention even under pressure variation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSystem customisation\u003c\/strong\u003e\u003cbr\u003eUse elbows to redirect flow without kinking pipe. Use tees to split one line into two. Use straight connectors to extend runs. End stops cap off branches. Non-return valves prevent backflow. Inline filters clean as you water. Each fitting type lets you adapt your system without rewiring the whole thing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAir lock prevention\u003c\/strong\u003e\u003cbr\u003eOne of the key strengths of barbed fittings is that the sealed design eliminates air pockets forming in the line, which means consistent nutrient delivery to all zones. Airlocks kill uniformity fast; these fittings stop that happening.\u003c\/p\u003e\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTubing compatibility: \u003cstrong\u003e13mm internal diameter (1\/2\" ID), typically 16–17mm external diameter LDPE pipe\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eMaterial: \u003cstrong\u003eUV-stabilised acetal plastic (copolymer)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eBarb design: \u003cstrong\u003eDouble-barbed for increased retention and pressure hold\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003ePressure rating: \u003cstrong\u003e0.5–3 bar optimal operating range\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eConnection type: \u003cstrong\u003ePush-fit (no tools required)\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eSeal method: \u003cstrong\u003eFriction fit + ratchet clamp recommended for LDPE applications\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eInstallation: \u003cstrong\u003eWarm tubing in hot water 10–30 seconds for easier insertion\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eAvailable connector types: Elbow, tee, straight, end stop, cross, non-return valve, anti-siphon valve, inline filter, flow control tap, reducers (13mm to 9mm, 13mm to 4mm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho this is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFirst-time growers building custom drip or hydroponic systems without professional tools\u003c\/li\u003e\n\u003cli\u003eExperienced growers scaling up or modifying existing setups efficiently\u003c\/li\u003e\n\u003cli\u003eAnyone adding extra pots or zones to an already-running system\u003c\/li\u003e\n\u003cli\u003eDIY irrigation projects where cost-per-fitting matters and flexibility is key\u003c\/li\u003e\n\u003cli\u003eGrowers who want to prevent air locks and kinks in their delivery lines\u003c\/li\u003e\n\u003cli\u003eBudget-conscious operators running multiple zones or pots from one water source\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eParticularly suited to systems where \u003cstrong\u003esimplicity, adaptability, and cost control matter more than permanent, sealed installation\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eOur take\u003c\/h3\u003e\n\u003cp\u003eBarbed fittings are the practical choice for anyone building irrigation from components rather than buying all-in-one kits. They're cheap, they're fast to fit, they handle pressure properly, and they let you modify your system without starting from scratch. The double-barbed acetal design holds properly — no cheap single-barb surprises halfway through the season.\u003c\/p\u003e\n\u003cp\u003eIf you're customising a hydroponic setup, splitting your main line to multiple zones, or just replacing a damaged fitting without buying a whole new kit, these are worth picking up. Good time to stock up while clearance pricing holds. Does the job reliably, day in and day out.\u003c\/p\u003e\n\u003c\/section\u003e","brand":"13MM FITTINGS","offers":[{"title":"13mm Barbed Tee Piece","offer_id":47916211994794,"sku":"92292","price":0.99,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed Elbow","offer_id":47916212027562,"sku":"86162","price":0.99,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed Cross Connector","offer_id":47916212060330,"sku":"94130","price":2.99,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed End Stop","offer_id":47916212093098,"sku":"89192","price":0.99,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed Anti-Siphon Valve","offer_id":47916212125866,"sku":"89238","price":7.99,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed Non-Return Valve","offer_id":47916212158634,"sku":"89199","price":6.99,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed Inline Filter","offer_id":47916212191402,"sku":"89196","price":4.49,"currency_code":"GBP","in_stock":true},{"title":"13mm Barbed Inline Flow Control Tap","offer_id":47916212224170,"sku":"86166","price":2.99,"currency_code":"GBP","in_stock":true},{"title":"13mm to 9mm Barbed Reducing Tee Piece","offer_id":47916212256938,"sku":"131193","price":1.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0053\/5540\/5400\/files\/13mm_barbed_fittings.jpg?v=1769189539","url":"https:\/\/growershouse.co.uk\/products\/13mm-barbed-fittings","provider":"Growers House ","version":"1.0","type":"link"}
