FloraFlex PotPro 16/17mm Fittings — Tool-Free Hydroponic Drainage Components
Best for: Growers building or expanding modular hydroponic systems who need reliable, leak-free connections without the faff
Our thoughts
These are the connectors that hold a FloraFlex system together. We bought heavy on stock, so you're getting proper hydroponic fittings at clearance pricing. Push-on installation, no tools, no adhesive — they just work. One we recommend a lot for anyone upgrading from older drip systems or building out a multi-pot setup.
FloraFlex PotPro 16/17mm fittings are the essential connectors in the PotPro drainage system, letting you build custom hydroponic setups without wrestling with compression clamps or barbed inserts. Made from lead-free TPR (Thermoplastic Rubber), they push straight onto 16/17mm double-layered tubing by hand — no tools, no mess. The system works with the tubing to block light and prevent algae, keeping your drainage lines clean and your water flowing properly.
How it compares
This is the FloraFlex standard in UK hydroponics. Here's how they stack up:
-
vs barbed fittings — No clamps needed, lower leak risk, easier to install and reconfigure
-
vs compression-style fittings — Faster setup, no tools required, compatible across the full PotPro range
-
vs budget alternatives — Lead-free TPR, rated to 80 PSI, designed for reliable long-term use in irrigation systems
FloraFlex has become the go-to system for growers scaling up. The ecosystem is solid, stock is reliable in the UK, and the fittings work as they should without the usual drip-irrigation drama.
Usage guidance
Basic setup
Push the fitting firmly onto 16/17mm tubing until it seats. The connection is hand-tight and watertight. No adhesive needed. If you need to change the configuration later, pull straight off and reconfigure — they're reusable.
T-fittings for single splits
Use a T-fitting when you need one incoming line to split into two outgoing lines. Common in two-pot or four-pot drainage layouts where you're collecting runoff into a single manifold.
Elbow fittings for directional changes
Route tubing around obstacles or drop water away from the saucer cleanly. Gets waste water moving in the direction you need without kinks or restrictions.
4-way fittings for complex systems
These let you split one incoming line into multiple outgoing directions. Useful when you're running a larger platform or multi-plant setup and need to organize drainage from several points into separate containers or a common manifold.
Platform fittings for PotPro integration
Platform fittings connect directly to your PotPro unit, creating the seamless junction between the platform and tubing. Essential if you're building a multi-unit system.
Pressure and safety
Rated to 80 PSI maximum, though emitter systems run best at 50 PSI or below. Use appropriate tubing, check connections before running, and inspect every few months for any sign of wear — fittings are reusable but not indestructible.

Who this is for
- Growers upgrading from barbed or compression fittings to a cleaner, tool-free system
- Anyone building a modular PotPro setup where flexibility and reconfiguration matter
- Multi-pot hydroponic growers who need reliable drainage lines without the constant worry of leaks
- Commercial or semi-commercial operations where system reliability and fast setup save time and money
- DIY hydroponic builders who value simplicity and don't want to wrestle with clamps or adhesive
Our take
These are properly engineered fittings that make building a hydroponic system actually straightforward. The fact that you can push them on by hand, reconfigure without tools, and trust them not to leak matters more than people think — especially when you're running multiple pots and can't afford downtime.
We bought heavy on stock, so clearance pricing applies. If you're scaling a PotPro system or replacing worn fittings from an older setup, good time to buy while stock lasts. Does exactly what it should, day in, day out.
