One Stop Outdoor Riser Adapter 4-Pack — 1/2" FPT/MPT to 1/4" Barbed Drip, UV-Resistant

One Stop Outdoor's riser adapter converts a 1/2" sprinkler riser into a combined sprinkler and drip outlet in seconds.

This compact adapter lets you add low-flow drip lines to existing riser-mounted high-pressure sprinkler heads so you can water lawns and beds from the same riser without re-plumbing. Made from UV- and chemical-resistant materials, the fitting installs between a 1/2" riser and a sprinkler device and features a side 1/4" barbed outlet for standard drip tubing. The result is flexible irrigation coverage that keeps shallow-rooted plants and deeply rooted turf happy using the same supply line.

How does this adapter let me run drip and sprinklers at the same time?

The adapter threads onto the riser and provides a side barbed port for 1/4" drip tubing while keeping the original 1/2" outlet for a sprinkler. This lets each riser feed both systems simultaneously when you split flow or use separate zones.

• Bottom: 1/2" female pipe thread (FPT) inlet to connect to riser
• Top: 1/2" male pipe thread (MPT) to accept a sprinkler head
• Side: 1/4" barbed outlet for standard drip tubing
• Works with existing riser-mounted sprinkler setups—no new trenching required

Will this part withstand outdoor exposure and irrigation chemicals?

The adapter is molded from rugged, UV-stable resin designed for long-term outdoor service and resistance to common irrigation chemicals. That durability helps prevent brittleness, cracking, or premature failure when left in-line season after season.

• UV-resistant material reduces sun-related degradation
• Chemical-resistant construction tolerates fertilizers and additives
• Solid molded design minimizes leak points under normal irrigation pressure

How easy is installation and what tools do I need?

Installation is straightforward: unthread the sprinkler from the riser, screw the adapter onto the riser, then attach the sprinkler to the adapter's top outlet and push 1/4" tubing onto the barb. Basic hand tools or a wrench to snug threads are usually all that’s required.

• Hand-tighten and finish with a wrench for a leak-free connection
• Push-fit 1/4" drip tubing onto the barbed side outlet—no glue needed for most systems
• Compatible with standard riser heights and sprinkler head styles

Can I use this with my existing drip tubing and emitters?

Yes—the adapter's 1/4" barbed outlet fits most small-diameter drip tubing and micro-sprayer lines. From there you can run tubing to emitters, micro-sprays, or drip lines for precise water placement.

• Connect directly to 1/4" drip tubing, micro-sprayer lines, or small distribution tubing
• Supports add-on emitters, inline drippers, and micro-spray fittings
• Ideal for spot-watering planting beds, containers, and shrub lines adjacent to lawn sprinkler coverage

Who is this for: This One Stop Outdoor riser adapter suits homeowners, landscapers, and irrigation hobbyists who want to expand an existing riser-based sprinkler system with drip watering. It’s especially useful when you need targeted irrigation for garden beds, containers, or shrub borders without altering the main sprinkler layout or installing separate supply lines. The product is intended for standard residential and light commercial irrigation systems and should be installed following local plumbing codes and irrigation best practices.
