Raindrip 1/4-Inch Barbed Tee 50-Pack — Black ABS UV-Stabilized Drip Irrigation Fittings

The Raindrip 307050B is a durable 1/4-inch barbed tee (50-pack) that joins three sections of supply tubing or creates a T-branch in dripline systems.

Use these compact ABS fittings to add intersections, branch off feeder lines, or repair micro-irrigation layouts without specialized tools. Each single-barbed tee fits 1/4-inch tubing (internal diameter ~0.170 in.) and is UV-stabilized to resist cracking, making it a practical choice for both new drip installations and incremental upgrades of existing systems.

How do I add a T-intersection to my drip tubing?

Installing a T-intersection is straightforward: soften the tubing if needed, push the single-barbed end into the opening, and seat the barb so it anchors the tee. The barb design holds tubing securely under typical garden pressures, letting you split a main line into two separate runs quickly.

• Fits 1/4-inch supply tubing or dripline with 0.170 in. internal diameter
• Insert single-barbed end into tubing opening and press until seated
• Soften tubing by soaking in hot water or warming in the sun for easier insertion
• Use for new layouts or to retrofit existing systems

Can I use these tees to create feeder branches from a larger supply line?

Yes — the barbed tee can connect two 1/4-inch branches to a punched hole in a larger supply line, enabling flexible feeder configurations. Make sure the punched hole matches the 0.170 in. diameter to ensure a snug, leak-resistant fit.

• Punch hole to approx. 0.170 in. for best fit
• Two 1/4-inch branches can be fed from one supply line
• Works for small beds, containers, and perimeter lines
• Good for expanding systems without re-laying the entire main line

What performance and material features should I expect?

These connectors are molded from ABS plastic treated with UV inhibitors so they resist sunlight-induced cracking and stay serviceable season after season. They handle typical drip irrigation pressures — up to roughly 50 psi — and are reusable if you need to reconfigure or relocate lines.

• Material: ABS with UV-stabilizing treatment
• Pressure rating: up to 50 psi under normal conditions
• Reusable for system changes or repairs
• Pack of 50 provides multiple installation or repair options

How do I troubleshoot leaks or poor fits?

Leaks most often come from mis-sized holes or tubing that hasn’t been fully seated over the barb. Trim tubing ends squarely, warm or soften stiff tubing, and press firmly until the barb is fully engaged. If a leak persists, replace the fitting or use a slightly larger punch to ensure a tight connection where appropriate.

• Trim uneven tubing ends for a flush seat
• Warm tubing to increase flexibility and ease installation
• Confirm punched holes match 0.170 in. spec for secure attachment
• Swap damaged fittings rather than forcing poor seals

Who is this for: Gardeners, landscapers, and DIY homeowners who install or maintain drip irrigation will find the Raindrip 307050B tees useful for building branching layouts, repairing small leaks, or expanding systems. The 50-piece pack is especially practical for larger projects, community gardens, or professionals who need reliable, UV-stable connectors that support common 1/4-inch micro-irrigation tubing.
