Use a threaded bulkhead where you want removable threaded plumbing on both sides of a drilled tank or sump. These black Schedule 40 tank adapters have a gasketed flange and threaded plumbing connections. Match the pipe size, drilled hole, and mating thread before purchase.

• 1/2 in: 1-1/8 in hole.
• 3/4 in: 1-1/2 in hole.
• 1 in: 1-3/4 in hole.
• 1-1/2 in: 2-3/8 in hole.

Install the gasket against the flange side. Avoid overtightening the bulkhead or threaded fittings. Pipe adapters and sealant are sold separately.
