Rubber Bulkhead Fittings

Rubber Bulkhead Fittings are the perfect solution for creating a watertight seal through tank walls, barrels, reservoirs, or fountain basins without the need for complex tools or adhesives. Made from flexible, heavy-duty EPDM rubber, these bulkheads are quick to install and form a tight, leak-resistant seal by simply inserting them into a pre-drilled hole and pushing a pipe through.

These bulkheads are ideal for pond plumbing, rainwater harvesting systems, IBC totes, aquaponics, and irrigation setups. Available in sizes 3/4", 1", 1-1/2", and 2", they accommodate standard Schedule 40 PVC pipe or flex tubing and are especially useful for curved or uneven surfaces.
