Premium Pure Black UPVC Structural Connectors (3D Framing)

Standard plumbing fittings restrict you to flat, two-dimensional designs and often feature a dull industrial look that ruins exposed architectural layouts. When you need to build a rigid 3D framework or a complex, multi-directional aquarium manifold, our Premium Pure Black UPVC Structural Connectors are the ultimate solution. Available in 3-way, 4-way, 5-way, and 6-way configurations, these "furniture-grade" joints allow you to expand your PVC pipeline in every direction. The sleek, high-gloss black finish not only looks incredibly professional but also provides 100% light-blocking protection against internal algae growth.

🌟 Key Engineering Features:

Furniture-Grade Durability: Engineered from high-impact UPVC. Highly resistant to shattering, UV degradation, and heavy structural loads, making them perfect for custom shelving, greenhouse frames, and filtration racks.

Multi-Directional Versatility: Seamlessly build perfect right angles, reinforced corners, and complex grid hubs using our precision-molded 3-way, 4-way, 5-way, and 6-way slip fittings.

Dual Installation Modes: Designed with tight-tolerance slip sockets. Simply "dry-fit" the pipes using friction for temporary/adjustable frameworks, or apply standard PVC solvent cement for a permanent, 1.0 MPa rated watertight seal.

Algae-Proof Aesthetic: The solid pure black construction completely blocks light penetration, safeguarding internal water quality for high-end reef aquariums and hydroponic reservoirs while offering a premium visual appeal.

📐 Installation Guide:

Sizing is listed by Internal Diameter (ID). For structural framing, firmly press the pipes into the sockets. For pressurized fluid applications, apply PVC cement to both the pipe exterior and fitting interior. Elevate your DIY builds and manifold designs today!
