This 1.5 inch bulkhead features a THREAD x THREAD connection. The rubber bushing always goes on the "wet" side of the tank or reservoir for a proper seal. Threaded pipes or fittings require Teflon tape in between the joint to ensure a water tight seal.
Threaded bulkheads are threaded on the inside and are typically used for aquarists wanting to use other plumbing pieces to thread inside the bulkhead such as strainers or THREAD x HOSE BARB fittings (going to hose instead of rigid PVC)
