Premium PVC Aquarium Union Bulkhead Fitting

Upgrade your aquarium plumbing with our Premium PVC Union Bulkhead Fittings. Available in both straight and 90-degree elbow designs, these connectors feature a clever single-head true union nut.

Why Choose Our Union Bulkheads?

• Quick Disconnect Union: The integrated union collar lets you unscrew the connection point in seconds. Perfect for hard-plumbed aquariums, sumps, and water tanks that require occasional disassembly.
• Premium Leak-Proof Seal: Manufactured from high-quality PVC and equipped with a durable, eco-friendly silicone gasket to ensure a watertight seal against your glass or acrylic tank walls.
• Straight & Elbow Options: Choose the straight connector for direct vertical drops, or the space-saving 90-degree elbow to route plumbing neatly against the back of your aquarium.
