2" PVC End Cap with 10mm Silicone Tube Adapter

Running a hydroponic setup or DIY irrigation line and can't find a fitting that actually bridges your silicone tubing to standard 2-inch PVC pipe? This end cap solves exactly that — it caps off your PVC pipe while routing a 10–12 mm silicone tube directly into the flow path. No bodged connectors, no hose clamps holding things together with optimism.

How it solves the problem

The cap seats firmly over the outside of a standard 2-inch PVC pipe (outer diameter 60.325 mm / 2.375") and integrates a barbed adapter sized for 10–12 mm inner diameter silicone tubing. The barbed profile grips the tube securely so it stays put under normal operating pressure. Apply a bead of silicone sealant or plumber's adhesive around the pipe joint and you have a watertight connection that won't surprise you mid-cycle.

Where it shines

• Hydroponic channels and NFT systems — connect nutrient delivery lines cleanly at the pipe end
• DIY garden irrigation — terminate a run of PVC pipe and tap in a feeder line without specialist tools
• Fluid transfer setups in workshops or lab environments where a neat, removable junction beats permanent pipe work
• Aquaponics plumbing where silicone tubing meets rigid PVC infrastructure

What you get

A single, ready-to-install end cap with integrated barbed tube adapter. It arrives ready to use — just push it onto your pipe, connect your silicone tube, seal the joint, and you're flowing. No assembly required beyond the installation itself.

For a fully watertight result, always apply silicone sealant or plumber's glue at the pipe socket joint before the adhesive sets. The barbed adapter handles the tube side; the sealant handles the pipe side. Together they give you a reliable, leak-resistant connection that holds up in wet, continuous-flow environments.

If you're building out a system with multiple runs, grab a couple — having a spare on the shelf saves a trip to the hardware store mid-build.
