Botanicare® Through-All Bulkhead Fitting - 3/4in Thread

Watertight Tank and Table Wall Penetration for Hydroponic Systems

The Botanicare Through-All Bulkhead Fitting provides a leak-free, permanent wall penetration point for flood tables, reservoirs, and tanks in ebb & flow, aeroponic, and drip hydroponic systems. Designed to mount through table and tank walls, it threads in from the outside and locks against the wall with a gasket seal to prevent leaks at the penetration point. Interior threads accept 3/4in standard pipe thread for direct connection to Botanicare flood fittings, PVC pipe fittings, and other compatible plumbing components — making it a central junction point in any flood table plumbing layout.

Frequently Asked Questions

What size hole do I need to drill for this bulkhead fitting?

Refer to the Botanicare product specification for the required hole diameter. Typically a step drill or hole saw is used to create a clean, correctly sized opening.

Does this fitting come with a gasket?

Botanicare ebb & flow fittings typically include the necessary gasket for wall sealing. Confirm inclusion with the product listing or contact your dealer if not specified.

Can I use this fitting in the bottom of a flood table?

Yes — bulkhead fittings are commonly installed in the floor or walls of flood tables for both feed and drain connections. Either placement uses the same gasket-sealed mounting method.

When is PTFE tape necessary on the interior threads?

Add PTFE (Teflon) tape whenever threading a male NPT fitting into this bulkhead's interior threads, since the gasket alone seals the wall penetration but not the threaded connection itself. Skipping the tape is a common cause of slow leaks at that joint.
