Construction Details
The SCI® Press Copper Reducing Coupling is identified as Fig. SP604R and uses a Press x Press reducing configuration for joining compatible copper tubing of two different nominal sizes.
SCI catalogs the fitting as SP604R CU P X P RED COUPLING. Each side incorporates an SCI Press connection sized for its corresponding copper tube, creating an integrated transition between the two tube sizes.
The fitting is manufactured as part of the SCI Press Copper system using copper alloy conforming to UNS C12200. Applicable press connections incorporate Grade “E” peroxide-cured EPDM sealing elements.
Important: SCI states that fluids containing hydrocarbon-based oils are not compatible with the EPDM seal and that SCI Press Copper EPDM fittings are not for use in petroleum applications.
Press x Press Reducing Configuration
Larger Press Connection
One side of the SP604R accepts the larger compatible copper tube size using the SCI Press mechanical connection system.
Smaller Press Connection
The opposite side accepts the corresponding smaller copper tube size, completing the straight in-line size transition without requiring a separate reducer and coupling.
Integrated Copper Tube Size Transition
The SP604R combines a straight coupling and reducing transition into one fitting. This allows a copper piping run to change nominal tube size while maintaining Press connections on both sides.
The fitting is useful where the piping layout needs to transition from a larger copper tube to a smaller copper tube without introducing a threaded adapter or another connection type.
Because both ends use SCI Press technology, the transition remains within the mechanical copper press system.
SP604R Connection Function
Connect
Provides an SCI Press connection for compatible copper tubing at both ends of the fitting.
Reduce
Transitions between different nominal copper tube sizes within the fitting body.
Continue
Maintains a straight-through piping direction while changing the nominal tube size.
Reducing Coupling vs. Standard Coupling
SP604R Reducing Coupling
The SP604R connects two different nominal copper tube sizes, providing an integrated reduction within a straight piping run.
SP604 Coupling with Stop
The SP604 is SCI's standard Press x Press coupling for joining compatible copper tubing of the same nominal size.
Reducing Coupling vs. FTG x Press Reducing Adapter Coupling
SP604R Reducing Coupling
The SP604R provides Press x Press connections on both sides, allowing two different copper tube sizes to be connected directly.
SP609R Reducing Adapter Coupling
The SP609R uses SCI's Male Street x Press reducing adapter configuration. Select the fitting configuration that matches the required connection types in the piping layout.
SCI® Press Copper Connection
SCI Press Technology provides a mechanical copper piping connection that eliminates the need for conventional soldering or brazing at the press joints.
SCI Press Copper Fittings are intended for use with ASTM B88 Types K, L, and M hard copper tubing and applicable soft copper tubing within the SCI Press Copper system.
The SCI Press Copper system is compatible with common pressing tools and jaws. SCI also states that fittings may be installed above and below ground where permitted by applicable local building codes.
Copper Tube Preparation & Pressing
Both copper tube ends should be properly prepared before installation. Follow the supplied SCI Press installation instructions for cutting, deburring, cleaning, inspection, insertion marking, fitting assembly, and pressing.
Because the SP604R connects two different tube sizes, verify the required size on each side of the fitting before installation and use the appropriate compatible pressing jaw for each connection.
After both connections are visually confirmed, the completed piping system should be pressure tested in accordance with applicable local code requirements.
EPDM Sealing System
The SCI Press Copper system uses peroxide-cured Grade “E” EPDM sealing elements. SCI lists an operating temperature range of -20°F to 248°F for the EPDM sealing material.
The EPDM seal is recommended by SCI for water service, diluted acids, alkaline solutions, oil-free air, and many other compatible chemical services.
Fluids containing hydrocarbon-based oils are not compatible with the EPDM seal. Do not use SCI Press Copper EPDM fittings in petroleum applications.
