The 3/4″ threaded bulkhead fitting in polypropylene (PP) is an ideal solution for equipping planters or grow tanks made of fiberglass that require a reliable, clean, and watertight drainage system. Designed to pass through a wall, this fitting allows for the installation of a tap, drain pipe, or any other irrigation or drainage system.

Made of high-strength polypropylene, it offers excellent resistance to external stresses such as moisture, liquid fertilizers, temperature variations, and moderate UV exposure. This material is also fully compatible with fiberglass, as it does not chemically react with the polyester resins commonly used in such planters.

The 3/4″ BSP thread ensures standard compatibility with common plumbing fittings (PVC, brass, HDPE...), while the included nut allows for a watertight mounting on thin walls, even without an integrated back nut. For optimal installation,

This bulkhead fitting is especially useful for:

• Installing a drainage system to prevent water stagnation at the bottom of the tank,
• Connecting pipes for a drip irrigation system,
• Creating an overflow outlet to prevent overfilling.

Its compact interior footprint ensures that it does not obstruct plant roots, while still providing good mechanical strength on the wall.
