1/4″ Cross Connector

The Auto Pot 1/4″ Cross Connector (SKU APWS058) is a single fitting designed to join four runs of 1/4″ tubing at one junction point. It is the correct size for older AutoPot AQUAvalve4 systems that use black/red valves and 1/4″ fittings throughout. Used alongside tee connectors, this part lets growers route feed lines in multiple directions from a single node, making it straightforward to extend or reconfigure an existing AutoPot layout without replacing the whole supply line.

1/4″ Cross Connector Specifications

The table below lists the key specifications for the Auto Pot 1/4″ Cross Connector as derived from the canonical product record and AutoPot system documentation.

Why Choose the Auto Pot 1/4″ Cross Connector

AutoPot gravity-fed systems depend on push-fit or barb-style tubing fittings to keep nutrient solution flowing reliably to each pot. Using the wrong size fitting — even by a small margin — leads to leaks or blockages at the junction. The 1/4″ cross connector is sized specifically for the older AQUAvalve4 generation, so it mates cleanly with 1/4″ supply tubing without adapters.

• Four-way branching from a single point. A cross connector splits one inlet into three outlets (or joins four runs), which reduces the number of individual tee fittings needed when routing lines across a row of pots.
• Correct sizing for AQUAvalve4 setups. AQUAvalve4 units (identified by their black body and red float) require 1/4″ fittings. The 3/8″ variant fits the newer AQUAvalve5 (gray/black) and is not interchangeable.
• Sold individually. Buy exactly as many as your layout requires. Growers can add connectors one at a time when expanding an existing system rather than purchasing a full fitting kit.
• Pairs with tee connectors. Combined with 1/4″ tee connectors, the cross connector gives growers the flexibility to design supply line paths that fit the physical footprint of their grow space.

Best Uses for the Auto Pot 1/4″ Cross Connector

This fitting is a maintenance and expansion part for growers already running AutoPot gravity-fed irrigation. Common situations where the 1/4″ cross connector is the right choice:

• Replacing a cracked or leaking junction in an existing AQUAvalve4-based system. Over time, plastic push-fit fittings can fatigue from UV exposure or repeated handling. Swapping a single connector is faster and cheaper than replacing full tubing runs.
• Extending a grow to additional pots. When adding pots to an existing row, a cross connector lets you branch off an existing line rather than re-routing the whole supply circuit.
• Creating a multi-directional layout. In irregular grow spaces — L-shaped rooms, greenhouse bays, or split bench setups — cross connectors allow supply lines to change direction at a node rather than requiring long tubing detours.
• Building a spare-parts kit. Growers running large AQUAvalve4 installations often keep a small stock of cross and tee connectors on hand so any fitting failure can be fixed immediately without waiting for parts.

If you are running an AQUAvalve5 system, you need the 3/8″ cross connector instead. For water quality upstream of your AutoPot reservoir, a 200-mesh inline filter can catch particulates before they reach your fittings and valves. For growers also managing dissolved oxygen levels, an air pump integrated into the reservoir can complement the passive AutoPot feed circuit.
