PVC bulkhead tank fitting

This Spears bulkhead tank fitting connects a flat-walled tank to external piping using 3-inch female threaded connections on both sides. The body is moulded from grey PVC and sealed with a neoprene gasket. It is rated for 150 psi at 73 degrees F and remains functional down to 0 degrees F.

Installers needing a straight-through tank

The zero-bolt-hole design suits tanks where drilling a bolt pattern is impractical or unwanted. Builders who require a flanged connection, a different gasket material, or a reduced-size outlet should select another fitting.

3-inch female threaded connections on both sides

This single specification decides whether the fitting matches the tank port and the downstream piping. Verify that both the tank opening and the mating pipe are 3-inch female thread before ordering.
