Why Choose Our Elbow Bulkhead Fittings?

• Space-Saving 90-Degree Design: The integrated elbow allows for immediate directional plumbing changes right at the bulkhead, perfect for tight spaces behind aquariums or inside crowded sump cabinets.
• Extended Full-Thread Design: The fully threaded outer body allows for a perfect, tight fit on tank walls of varying thicknesses. You no longer need to cut short the threaded pipe for thinner glass—simply tighten the nut for a secure hold.
• Leak-Proof Silicone Gasket: Unlike standard rubber rings that harden and crack over time, our included high-quality silicone gaskets provide superior, long-lasting sealing performance under high water pressure, ensuring zero leaks.

⚠️ Installation Guide: The size listed in the options refers to the Interface Inner Diameter (ID), which corresponds to the Outer Diameter (OD) of the PVC pipe you are connecting. Please follow these drilling specifications: 20mm ID (Hole 20-23mm, Clamps 0-15mm), 25mm ID (Hole 25-28mm, Clamps 0-20mm), 32mm ID (Hole 32-35mm, Clamps 0-20mm), 40mm ID (Hole 40-43mm, Clamps 0-22mm), and 50mm ID (Hole 50-55mm, Clamps 0-25mm). Apply aquarium-safe PVC solvent cement to bond your pipe into the slip socket.
