PP Barbed Branch Coupling — Derivation Barbed for 11–20mm Tubing

Iteam Number:GRPF0010

PP Barbed Branch Coupling — Derivation Barbed for 11–20mm Tubing

PP barbed coupling that runs a branch off a mainline or joins two lengths of tubing, in four combinations from 11×16 to 20×20. Both ends carry multi-ring barbs and a flange between them sets insertion depth on both sides, so the joint stays straight without a clamp on low-pressure lines. The H/T type rubber seal ring is supplied separately, so order it together where the joint needs a gasket. OEM, ODM and OBM are supported, with body colour matched to your sample or colour code.

2.Product Feature

  • Multi-Ring Barb Grip:Each spigot carries several barb rings, so the tube wall is gripped at more than one point and pull-out load spreads along the insertion depth instead of sitting on a single ridge.
  • Flange Sets Insertion Depth:A flange between the two ends stops the tube at a fixed depth on both sides, keeping the coupling straight and stopping the tube from being pushed through.
  • Push-On Branch Take-Off:No thread, no glue and no tool — push the tube over each barb and the branch or repair is done, which suits mid-season changes.
  •  Built For H/T Type Systems:The coupling is designed to work with the H/T type rubber seal ring, which is ordered separately so you only pay for the ring where the joint actually needs one.

3.Product Application

Used to run a branch off a 16 or 20mm mainline onto 11, 16 or 20mm tubing, or to bridge a cut lateral — greenhouse benches, nursery pot lines, orchard sub-laterals, landscape beds and garden drip kits.

Yes. We have pressure-regulating bodies and valves to stabilize nozzle pressure, reduce misting, and improve uniformity in varied elevation or long laterals.

22.How do you solve the clogging problem in micro and drip sprinkler systems?

Use appropriate pre-filtration (disc/screen/centrifual/hydrocyclone), maintain filters regularly, flush lines 5–10 minutes at startup, and manage fertilizer concentration to avoid precipitation. For marginal water, consider chemical treatment and periodic acid/chlorination as per local standards.

23.How does an irrigation system work?

It draws water from sources (rivers, wells) via pumps/gravity, transports it through main/sub-main/lateral pipes, and delivers it to plant roots via sprinklers/drip emitters. Modern systems add filters (anti-clog) and sensors (adjust flow by crop/weather).​

24.What is drip line irrigation?

A micro-irrigation method: perforated plastic tubes with emitters deliver water slowly (2—12L/h) directly to roots. It saves water (95% utilization), has filters/regulators, suits arid areas/high-value crops, and can mix nutrients.​
