Description
Splice a damaged drip lateral or join two reels of 1/2″ poly tubing into one continuous run without an extra trip to the truck. The Rain Bird SBCPLG is a straight inline coupling with 1/2″ insert barbs on both ends — cut the tubing where the cut is needed, slide each end onto a barb, clamp it down, and you’re done. Glass-filled engineering plastic body that survives the trench drops, the freeze-thaw cycles, and the UV that destroys cheap import barbed couplings in a season.
Why Installers Pick the SBCPLG
- Two matched 1/2″ insert barbs — both ports take standard 1/2″ poly drip tubing (.700″ OD class)
- Glass-filled plastic body — UV-, soil-, and freeze-thaw-stable for buried OR surface-laid drip lines
- Rain Bird quality control — consistent barb OD batch-to-batch, so clamps seat properly every time
- Compatible with Oetiker 1-ear stainless clamps, worm-drive clamps, or any standard 16–18 mm closing-range clamp
- Single-piece body — no welds, no glue joints, nothing to fail under pressure
- Lower profile than a tee fitting — the coupling lays flat in a tight trench or low-clearance bed
Where It Shines
- Splicing a drip line that got cut by a shovel, root, or rodent — cut the damaged section out, drop a coupling in
- Joining two partial reels of 1/2″ poly tubing into a single continuous lateral
- Extending an existing drip run — coupling on the cut end, new tubing on the far side of the coupling
- Service-call patches replacing failed import barbed couplings or split tubing sections
- Repair work on buried emitter lines where you don’t want to dig up the whole zone

- Recommended clamp: Oetiker 1-ear stainless or equivalent worm-drive (16–18 mm closing range)
- Use: Buried or surface, residential / light commercial drip irrigation
- Approximate weight: 1 lb per pack
- Origin: Rain Bird
Install Notes
- Slide a clamp onto EACH tubing end BEFORE pushing onto the barbs — you can’t open clamps after the tubing is seated
- Cut the tubing square with a sharp knife or PE pipe cutter (a ragged cut won’t seal)
- Push each tubing end fully home onto the barb — the last barb ridge should be fully covered
- Position the clamp over the barb body and crimp / tighten (one clamp per port = two clamps total)
- Pressure-test before backfilling the trench
- If you’re cutting into an existing pressurized line, shut the zone off at the valve first
Pair With
For a branch instead of an inline splice, use the Rain Bird SBTEE three-way tee. For the threaded-to-barb transition off a buried supply, use the SBE050 or SBE075 barb elbow.
