Detachable UPVC Aquarium Union Bulkhead Fitting

Simplify your aquarium plumbing and future-proof your maintenance with the Single-End Union Bulkhead from Atradesen.com. Designed for both upper return and lower drain lines, this premium UPVC tank connector features a built-in quick-release union, making it the absolute best choice for complex sump systems that require occasional disassembly, deep cleaning, or safe tank transportation.

🌟 Premium Quick-Release Features

• Single-End Union Design: The integrated threaded union nut allows you to instantly detach your connected PVC pipe network from the tank without ever cutting a glued joint! A true lifesaver for moving tanks or upgrading equipment.
• Extended Threading & Secure Seal: The extended male thread safely clamps through thick glass or acrylic walls. Paired with high-quality gaskets, it provides a highly reliable, leak-proof seal.
• Industrial Grade PVC: Manufactured from premium, drinking-water-safe PVC. Connects permanently to your hard plumbing using standard PVC cement.

⚠️ Sizing & Installation Guide (Crucial!)

Avoid ordering the wrong size and delaying your build! Please read the Atradesen.com sizing rule carefully before purchasing:

• Matching Rule: The size you select from the dropdown menu (e.g., 20mm) represents the Inner Diameter (I.D.) of the fitting's socket.
• Pipe Compatibility: An I.D. 20mm fitting will perfectly sleeve over a PVC hard pipe with a 20mm Outer Diameter (O.D.).
• Installation Note: PVC waterproof adhesive/glue MUST be used on the slip joints to secure your pipes (glue not included). Tighten the bulkhead nut securely to ensure maximum leak prevention.
