Airmax Junction Valve Box With Lid

The Junction Valve Box with Lid provides a clean, protected access point for airline connections beneath an aeration cabinet. It allows airlines and flex tubing to be connected, disconnected, or serviced without disturbing the cabinet or surrounding landscape.

This box can be used with any aeration system and is available either without holes for standard cabinet installations or with pre-drilled holes for use with remote manifold kits. Once installed, it keeps connections organized, protected, and easy to access when maintenance or seasonal removal is needed.

Why Choose the Junction Valve Box?

• Easy Access: Provides direct access to airline connections under the cabinet.
• Clean Installation: Keeps tubing and fittings organized and protected underground.
• Flexible Use: Available solid or pre-drilled for remote manifold applications.
• Service Friendly: Simplifies cabinet removal and seasonal maintenance.
• Durable Design: Built to withstand underground installation conditions.

Installation Overview

• Excavate: Dig a level hole approximately 13" x 18" x 6".
• Position Box: Place the junction box to confirm fit and alignment.
• Route Tubing: Feed compressor flex tubing beneath or through pre-drilled holes.
• Set Cabinet: Place the aeration cabinet over the junction box.
• Connect Airlines: Attach airlines to the compressor flex tubing.
• Backfill: Secure the box by backfilling soil around it.

PRO TIP

Before backfilling, leave a small service loop in the airline inside the box. This extra slack makes future reconnections or upgrades much easier without re-digging.
