Plan the entire plumbing run before gluing because slip connections become permanent once solvent-welded. Place the gasket on the wet side of the panel and tighten the lock nut by hand to avoid damaging the fitting or panel. Directions for Use Drill the required hole through a clean, flat panel, smooth any rough edges, and remove debris. Insert the bulkhead with the gasket on the wet side, then hand-tighten the lock nut. Install the strainer, elbow, and compatible slip plumbing as required, allow glued joints to cure, and leak-test thoroughly before regular operation.
