Description
SCI® Press - Copper 90° Reducing Elbow
SCI® Press - Copper 90° Reducing Elbow combines a 90-degree change in direction with a reduction between two different copper tubing sizes in one compact press fitting.
Identified by SCI as Fig. SP690R, this reducing elbow uses a Press x Press reducing configuration and is manufactured from copper alloy conforming to UNS C12200. The SCI Press Copper system incorporates peroxide-cured Grade “E” EPDM sealing elements and provides a mechanical copper piping connection without conventional soldering or brazing.

Construction Details
The SCI® Press Copper 90° Reducing Elbow is manufactured with a copper alloy body conforming to UNS C12200. Its two press connections are sized differently so the fitting can reduce between compatible copper tubing sizes while simultaneously changing the piping direction by 90 degrees.
The SCI Press Copper connection incorporates a Grade “E” peroxide-cured EPDM sealing element with silicone grease. SCI specifies an EPDM operating temperature range of -20°F to 248°F.
SCI recommends the EPDM material for water service, diluted acids, alkaline solutions, oil-free air, and many other compatible chemical services.
Important: SCI specifically states that fluids containing hydrocarbon-based oils are not compatible with the EPDM seal and that these fittings are not for use in petroleum applications.
90° Reducing Configuration
90-Degree Direction Change
The SP690R redirects the copper tubing run by 90 degrees, making it useful where the piping layout needs to turn at a right angle.
Built-In Size Reduction
The two press ends are different nominal sizes, allowing the elbow to transition between larger and smaller compatible copper tubing without adding a separate reducer to the piping arrangement.
Reducing Elbow vs. Standard 90° Elbow
SP690R Reducing Elbow
The SP690R combines a 90-degree turn with a reduction between two different tubing sizes. This can simplify installations where both a directional change and a size transition are required at the same location.
SP690 Standard Elbow
The standard SP690 Press Copper 90° Elbow connects equal-size copper tubing on both ends. Select the reducing SP690R when the two connected tubing sizes are different.
SCI® Press Copper Connection
SCI Press Technology provides a mechanical copper piping connection that eliminates the need for conventional soldering or brazing. The system is compatible with common pressing tools and jaws.
SCI Press Copper Fittings are intended for use with ASTM B88 Types K, L, and M hard copper tubing from 1/2" through 4" and soft copper tubing from 1/2" through 1-1/4".
SCI states that its Press Copper fittings are approved for installations above and below ground where permitted by applicable local building codes.
ASTM B88 Copper Tubing Compatibility
Hard Copper Tubing
The SCI Press Copper fitting system is intended for use with ASTM B88 Types K, L, and M hard copper tubing in sizes from 1/2" through 4".
Soft Copper Tubing
SCI also specifies system compatibility with ASTM B88 soft copper tubing in sizes from 1/2" through 1-1/4". Always confirm that both sides of the reducing connection are compatible with the tubing being installed.
EPDM Sealing Element
The SCI Press Copper system uses a peroxide-cured Grade “E” EPDM O-ring. SCI lists an operating temperature range of -20°F to 248°F for this 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 these fittings in petroleum applications.

Frequently Asked Questions
What is the SCI figure number for this Copper 90° Reducing Elbow?
SCI identifies the Press Copper 90° Reducing Elbow as Fig. SP690R.
What connection configuration does the SP690R use?
SCI identifies the SP690R as a CU P x P RED 90 ELL, meaning it uses two press connections of different sizes in a 90-degree reducing-elbow configuration.
What does a reducing 90° elbow do?
It changes the piping direction by 90 degrees while simultaneously transitioning between two different nominal copper tubing sizes.
How is the SP690R different from the standard SP690?
The standard SP690 connects equal-size tubing on both ends. The SP690R uses different inlet sizes so the fitting can provide a size reduction and a 90-degree turn in one component.
What material is the fitting made from?
SCI specifies a copper alloy body conforming to UNS C12200.
What type of seal does SCI Press Copper use?
The system uses a peroxide-cured Grade “E” EPDM sealing element with an operating temperature range of -20°F to 248°F.
What copper tubing is compatible with the SCI Press system?
SCI specifies ASTM B88 Types K, L, and M hard copper tubing from 1/2" through 4", as well as ASTM B88 soft copper tubing from 1/2" through 1-1/4".
What is the water-system rating?
SCI publishes a 300 PSI rating for water systems with a 600 PSI test pressure and an EPDM service temperature range of -20°F to 248°F.
Can SCI Press Copper fittings be used for petroleum applications?
No. SCI states that fluids containing hydrocarbon-based oils are not compatible with the EPDM seal and that these fittings are not for use in petroleum applications.
Does installation require soldering or brazing?
No. SCI Press Technology provides a mechanical press connection that eliminates the need for conventional soldering or brazing.
What certifications does the SCI Press Copper system carry?
SCI identifies IAPMO UPC PS-117, NSF/ANSI 61, and NSF/ANSI 372 approvals and certifications for the system.
