Construction Details
The SCI® Press Copper Coupling with Stop is identified as Fig. SP604 and uses a straight Press x Press configuration for joining compatible copper tubing.
SCI catalogs the fitting as SP604 CU P X P CPLG. An internal tube stop is incorporated into the coupling body to help establish the insertion position of the adjoining copper tube ends.
The fitting is manufactured as part of the SCI Press Copper system using copper alloy conforming to UNS C12200. The two 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.
Coupling with Internal Stop
Press x Press Connections
Both ends of the SP604 provide SCI Press connections for joining compatible copper tubing in a straight-through piping configuration.
Internal Tube Stop
The internal stop helps position each tube end within the coupling and provides a defined center point during assembly.
Standard Straight-Through Connection
The SP604 is designed for common installations where two compatible sections of copper tubing need to be joined in a straight line.
Each tube is prepared and inserted into its respective end of the coupling until properly positioned at the internal stop, then the two press connections are completed with compatible pressing tools and jaws.
The stop helps simplify tube placement compared with a no-stop coupling, although proper tube preparation, insertion marking, inspection, and pressing procedures should still be followed.
SP604 Connection Function
Join
Connects two compatible sections of copper tubing in a straight piping run.
Position
The internal tube stop helps establish the proper position of the adjoining tube ends within the fitting.
Press
Both fitting ends are mechanically joined using compatible SCI Press tools and jaws.
SP604 vs. SP605 Coupling No Stop
SP604 Coupling with Stop
The SP604 includes an internal tube stop that helps position both tube ends during a standard straight-through installation.
SP605 Coupling No Stop
The SP605 does not include an internal stop, allowing the coupling to slide along compatible copper tubing during repair and retrofit work.
SP604 vs. SP605L Extended Coupling No Stop
SP604 Standard Coupling
The SP604 is intended for conventional straight-through connections where the internal stop assists with tube placement.
SP605L Extended No Stop
The SP605L is SCI's extended no-stop coupling and provides additional fitting length and sliding positioning capability for applicable repair and retrofit installations.
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 system is compatible with common pressing tools and jaws. SCI also states that Press Copper fittings may be installed above and below ground where permitted by applicable local building codes.
Tube Preparation & Positioning
Proper tube preparation remains important even though the SP604 incorporates an internal stop. The copper tubing should be cut square, deburred, cleaned, inspected, and marked according to the SCI Press installation instructions before insertion.
Insert each prepared tube into the coupling to the required position before pressing. Confirm that the fitting remains properly aligned and that the sealing elements have not been damaged or displaced during assembly.
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.

Frequently Asked Questions
What is the SCI figure number for the Copper Coupling with Stop?
SCI identifies the Copper Coupling with Stop as Fig. SP604.
What is the SCI catalog configuration for the SP604?
SCI catalogs the fitting as SP604 CU P X P CPLG.
What connections does the SP604 use?
The SP604 uses a straight Press x Press configuration for joining compatible copper tubing.
What does “with Stop” mean?
The coupling incorporates an internal tube stop that helps establish the insertion position of each copper tube end within the fitting.
How is the SP604 different from the SP605 No Stop Coupling?
The SP604 includes an internal tube stop. The SP605 does not, allowing the no-stop coupling to slide along the tubing during repair or retrofit installations.
When should I use the SP604?
The SP604 is well suited for standard straight-through copper piping connections where the internal stop can assist with tube positioning.
Does installation require soldering or brazing?
No. SCI Press Technology provides mechanical press connections that eliminate conventional soldering or brazing at the joints.
Do I still need to mark the tubing even though the coupling has a stop?
Yes. Follow the SCI Press installation instructions for tube preparation and insertion marking. The internal stop assists with positioning but does not replace proper installation procedures.
What sealing material does SCI Press Copper use?
SCI specifies peroxide-cured Grade “E” EPDM sealing elements with an operating temperature range of -20°F to 248°F.
