This product page focuses on the Uponor WGF upper valve part designed for 1-inch manifold pipes. It is compared with other plumbing components from the same brand, such as the Up-Kolano Ppsu20 press elbow, the S-Press fitting with a male thread (16 mm × R3/4), the press fitting with a female thread (16 mm – Rp 1/2), as well as an end feed tee and plumbing elbow (models 1039944 and 1039929). While all these items are manufactured by Uponor and utilized in plumbing and heating systems, they serve fundamentally different purposes: the main product acts as a flow control and regulation element for a manifold, whereas the alternative items function as connection fittings, elbows, and tees used to join pipes or change routing directions.
⚙️ The table below compares product types, primary purposes, system compatibility, and installation characteristics.
| Comparison parameter | Uponor WGF upper valve part for 1 inch manifold pipe | Press elbow Uponor Up-Kolano Ppsu20 90° | Uponor S-Press fitting 16 mm × R3/4 | Uponor press fitting 16 mm – Rp 1/2 | End feed tee Uponor 1039944 | Plumbing elbow Uponor 1039929 | Practical significance of differences |
|---|
| Product type | Manifold upper valve part | 90° press elbow | Press fitting with male thread | Press fitting with female thread | End feed tee fitting | Plumbing elbow fitting | Each component performs a distinct function: flow regulation, angular pipe connection, or branching. |
| Purpose and application | Flow control and regulation within 1-inch heating and plumbing manifold pipes | Creating a compact right-angle connection for PPSU20 pipe systems | Transitioning from a press pipe to a threaded R3/4 connection | Providing a threaded Rp 1/2 outlet for valves or fixtures | Establishing a three-way branch point in distribution networks | Redirecting flow between joined pipe segments | The main product manages flow at the manifold, while alternatives are used to assemble the pipeline network itself. |
| Compatibility | Designed for 1-inch Uponor manifold pipes | Designed for PPSU20 pipe systems | Designed for plastic and multi-layer press pipes | Designed for compatible press tools and PEX/composite pipes | Designed for end feed/sweat joining methods | Standard residential and commercial plumbing layouts | Requires correctly matched system components, manifolds, or pipe types for proper installation. |
◎ The table below evaluates which product is most suitable for various installation scenarios and user needs.
| Usage scenario | Recommended product | Why this choice is optimal |
|---|
| Regulating flow on a distribution manifold | Uponor WGF upper valve part for 1 inch manifold pipe | Engineered specifically to integrate into 1-inch heating and plumbing manifolds. |
| Making a 90-degree corner for PPSU20 pipes | Press elbow Uponor Up-Kolano Ppsu20 90° | Provides a secure, leak-resistant right-angle connection for the corresponding pipe type. |
| Connecting pipes to threaded assemblies | Uponor S-Press fitting 16 mm × R3/4 or Uponor press fitting 16 mm – Rp 1/2 | Enables a safe and reliable transition from press piping systems to threaded fixtures or valves. |
| Branching or routing pipeline paths | End feed tee Uponor 1039944 or Plumbing elbow Uponor 1039929 | Suited for changing direction or splitting flow in domestic water and heating circuits. |
Recommendation: The Uponor WGF upper valve part is built specifically to regulate water flow inside manifold assemblies and does not replace connecting fittings. Choose this product if you need a replacement regulation component for a 1-inch manifold. If your goal is to assemble pipe runs, create corners, adapt to threaded components, or establish branch lines, you will need the appropriate fittings from the alternative options.
