Bulkhead Fittings

Fiberglass bulkhead fittings provide a simple, reliable way to create a sealed threaded pipe connection through the wall of a tank, vessel, sump, or other container. Designed for strength, corrosion resistance, and dependable sealing, they are widely used in chemical processing, water and wastewater treatment, agriculture, and other industrial applications.

Heartland Fiberglass Supply offers compression-molded fiberglass bulkhead fittings that provide secure, leak-resistant connections while remaining lightweight and highly resistant to corrosion. Available in a range of sizes, our bulkhead fittings are ideal for new installations, repairs, and replacement applications.

Choose from two proven resin systems to match your application: Isophthalic Polyester (ISO) or Vinyl Ester (HETRON® 922).
