Description
The 90-degree fitting that turns a buried PVC manifold or PE supply line into a side-port drip outlet without an extra trip to the truck. Rain Bird’s SBE-series barb elbow has male NPT threads on one leg (1/2″ or 3/4″, depending on the variant) and a 1/2″ insert barb on the other — thread it into a tee, coupler, or PE insert fitting, slide 1/2″ poly tubing onto the barb, and clamp it down. Glass-filled engineering plastic body takes the trench abuse that breaks cheaper imported elbows.
Why Installers Pick the SBE
- Male NPT to 1/2″ barb in a single fitting — eliminates the male-MIPT adapter plus barb fitting stack that adds two leak points
- 90° geometry — runs the lateral tubing up and out of the trench at right angles to the supply line
- 1/2″ barb size matches industry-standard 1/2″ drip and lateral poly tubing (.700″ OD class)
- Glass-filled plastic body — resilient to UV, soil chemistry, and freeze-thaw
- Rain Bird quality control — consistent barb OD batch-to-batch (no surprise loose-fit clamps)
- Compatible with Oetiker stainless 1-ear clamps, worm-drive clamps, or the standard Rain Bird SBE-clamp on the barb side
Pick Your Inlet Thread
- 1/2 in. (SBE050) — 1/2″ male NPT into a 1/2″ female-threaded tee, coupler, or supply fitting. The right pick for most residential drip manifolds and 1/2″ supply laterals.
- 3/4 in. (SBE075) — 3/4″ male NPT into a 3/4″ female-threaded fitting. Use when stepping down off a 3/4″ main into a 1/2″ drip lateral, or when the supply tee on the manifold is 3/4″.
Both versions deliver the SAME 1/2″ barb on the outlet side — only the inlet thread size differs.
Where It Shines
- Drip irrigation manifold builds — pop the SBE into the manifold tee, run 1/2″ poly to each plant or emitter
- Bed and shrub zone laterals — transition from a buried PVC main to a surface-laid 1/2″ drip line
- Service-call patches — replace failed import barbs that lost their barb ridges or cracked at the thread
- Foundation drip kits and Xerigation installs where every leak point matters

Install Notes
- Wrap the male NPT threads with 2–3 layers of PTFE tape (or use approved pipe-thread sealant); hand-tight plus a quarter turn with a wrench
- Slide the clamp over the poly tubing BEFORE pushing the tube onto the barb
- Push the tubing fully home onto the barb — the last barb ridge should be fully covered by tubing
- Position the clamp over the barb body and crimp / tighten
- Pressure-test the fitting before backfilling the trench
