Manifold Sourcing R553D with 1in x 3/4in connections, model R553EY002, 2-ring configuration

The Sourcing R553D manifold with 1in x 3/4in connections in a 2-ring configuration is a hydraulic distribution component intended for plumbing and heating systems. It provides a compact solution for splitting flow between an inlet and two outlet circuits where pipe size transition from 1in to 3/4in is required. The unit is suitable for installations such as radiator banks, underfloor heating manifolds, and other hydraulic circuits that need a reliable, fixed connection point for directing fluid to separate zones.

Advantages

The manifold offers a simple, space-saving form factor with two rings to serve dual circuits from a single inlet. Its 1in to 3/4in connection sizing allows direct coupling between common trunk lines and smaller branch pipes without additional adapters. The design supports orderly distribution of flow and helps centralize connections for easier maintenance and system layout clarity.

Suitable for

• Radiator systems requiring a single inlet feeding two separate radiator circuits
• Underfloor heating installations where a main feed must split to two zones
• Hydraulic circuits in residential or light-commercial buildings needing pipe size transitions
• Replacement or upgrade of existing manifolds with matching connection sizes

When it may not be suitable

The R553D is designed specifically for two-circuit distribution with the stated 1in and 3/4in connection sizes; it is not suitable where more than two outlets are required or where different connection dimensions are needed. Systems that require integrated balancing valves, metering, or flow regulation components built into the manifold will need a different model with those features.

Key specifications

• Connection sizes: 1 inch inlet to 3/4 inch outlets
• Configuration: 2-ring (two outlet circuits served from one inlet)
• Intended use: distribution for plumbing and heating applications
• Compatibility: suitable for common radiator and underfloor heating pipework sizes that match the connection dimensions

How to use

Install the manifold in the system where the main feed line can be connected to the 1in inlet and the two 3/4in branch lines attach to the outlet rings. Ensure the manifold is secured and oriented according to the installer’s best practice for accessibility and support. Perform pressure testing and flushing of the circuit after installation to confirm leak-tight joints and to clear debris. Integrate with existing valves, pumps, or balancing elements as required by the system design.

What to consider before purchase

• Confirm that your system pipe sizes match the 1in inlet and 3/4in outlets
• Verify that a two-circuit manifold meets the zoning requirements of your installation
• Determine whether additional components (valves, meters, air vents) are needed separately
• Check material compatibility with your system fluid and operating temperatures

Usage recommendations

Use the manifold as part of a complete distribution assembly, and pair it with appropriate isolation valves and monitoring devices if flow control or balancing is required. Have installations performed or verified by a qualified heating/plumbing professional to ensure correct connections, system sealing, and compliance with local codes.
