This pipe fitting kit provides versatile connections for tubing with diameters from 4 mm to 16 mm and includes a T-shaped option for branching. It covers common sizing needs with a reducing piece, a hose connection, and a 6-4-6 outer diameter adapter. Included items - Pipe fittings for diameters 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, and 16 mm, including a T shape - Reducing piece to transition between different tube sizes - Hose connection for attaching flexible hoses - Connection adapter with an outer diameter of 6–4–6 mm - 6 4 6 mm O.D. Key benefits - Wide compatibility: fits standard tubing sizes from 4 mm to 16 mm, enabling flexible system design - Branching capability: T-shaped fitting allows splitting flow to two lines - Size transitions: reducing piece and 6-4-6 mm adapter support transitions between different tube diameters - Flexible applications: suitable for a range of general tubing connections in DIY, workshop, or small-scale projects Specifications and compatibility - Diameters covered: 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm - Special fittings: T-shaped fitting included - Reducing piece for size changes - Hose connection for flexible hoses - Connection adapter: outer diameter 6–4–6 mm - Extra note: 6 4 6 mm O.D. specification listed Practical use scenarios - Scenario 1: Garden irrigation Use the T-shaped fitting to create a branch from an 8 mm main line to two 6 mm secondary lines. Use the reducing piece to adapt a 10 mm line down to 6 mm where needed, and employ the 6–4–6 mm adapter to connect a 4 mm branch line to a 6 mm main line. - Scenario 2: Small workshop tubing network Build a compact tubing network with varying diameters. Combine different sizes using the reducing piece and the adapter to join 6 mm and 4 mm segments, and use the T piece to route flow to two different devices. - Scenario 3: Prototyping and testing Quickly assemble test rigs that require multiple tube sizes. Switch between diameters with the reducing piece and adapter, while the T-shaped fitting provides quick branching for parallel testing paths.
