Why Choose Our Extended Bulkheads?

• Widened & Extended Design: The extended middle threaded pipe easily clamps glass up to 25mm thick. If the thread is too long for thinner glass, it can be easily sawn short without affecting functionality. The widened nut ensures a larger contact surface for superior stability.
• Premium Silicone Gasket: Each fitting comes equipped with widened and thickened premium silicone gaskets of moderate hardness, delivering excellent, long-lasting sealing performance under high water pressure.
• Versatile Configurations: Available in three practical styles as shown in our reference image 8_002.jpg: Straight-to-Straight, Straight-to-Elbow, and Elbow-to-Elbow to perfectly match your specific plumbing routing needs behind or under the tank.

⚠️ Drilling & Sizing Guide: The interface inner diameter perfectly matches your PVC pipe's outer diameter. For a 20mm fitting, drill a 20mm hole; for 25mm, a 25mm hole; for 32mm, a 32mm hole; for 40mm, a 40mm hole; and for 50mm, a 50mm hole. If your tank wall exceeds the default 25mm clamping thickness, please contact our customer service for custom extended thread options.
