Crucial Installation Guide & Features

• Two Connection Styles: Choose Female Thread to connect standard threaded pipe fittings, or Slip Socket to cement directly onto the outer diameter of your PVC pipes.
• Reverse Thread Design (Important): The large outer thread of the bulkhead is a REVERSE (left-handed) thread. It is designed EXCLUSIVELY for the locking nut to secure the fitting to your tank wall. You cannot attach other plumbing fittings to this outer thread.
• Hole Sizing: The required drill hole size for your tank equals the Outer Diameter (OD) of the bulkhead's outer thread. E.g., 20mm/25mm requires a 35mm hole, 32mm requires 45mm, and 40mm/50mm requires 64mm.
