REDUCER 19mm-13mm

Description

REDUCER 19MM-13MM is the push-fit irrigation fitting that connects 19mm main distribution pipe to 13mm secondary irrigation tubing, an essential component for any grower building or expanding a modular drip, flood-and-drain, or AutoPot-style irrigation network. We have been supplying irrigation fittings and hydroponics system components to UK growers since 2017, and having a stock of quality reducers prevents the frustration of mismatched pipe sizes derailing your grow room plumbing.

Where the 19mm to 13mm Reducer Is Used

Many larger hydroponic header tanks and flood tables use 19mm outlets as the main water feed line, while the distribution network running to individual pots and growing sites uses the more flexible 13mm pipe. The reducer creates a clean, watertight transition between the two diameters using a push-fit mechanism that requires no tools, adhesive, or thread tape. It is rated for the low-pressure gravity-feed conditions of standard hydroponic systems and is compatible with standard LLDPE irrigation tubing from all major suppliers including AutoPot, Nutriculture, and generic horticultural suppliers. Keep several in your spares kit — they are small, inexpensive, and surprisingly easy to lose.

Fitting and System Integrity Tips

Ensure both pipe ends are cut cleanly and squarely before inserting into the reducer — a diagonal cut creates an imperfect seal and allows drips over time. Push both pipes fully home until they seat against the internal stop and give a gentle tug to confirm the fit is secure before pressurising the system. If pipe feels loose, briefly warm it in warm water to soften the material before refitting. Check all fittings for drips when first running water through any new or modified system layout, and keep a dry cloth handy to identify hairline seeps at joints that may not be visible as drips.

Keep a supply of Reducer 19mm-13mm fittings alongside Y-connectors, end caps, and 13mm distribution pipe for a fully stocked irrigation spares kit that keeps any grow room water system running without interruption.
