Frequently Asked Questions
What is the SCI Press Copper Reducing Coupling used for?
It connects two different sizes of compatible copper tubing in a straight press piping run.
What figure identifies the SCI Press Copper Reducing Coupling?
ASC Engineered Solutions identifies the SCI Press Copper Reducing Coupling as Fig. SP604R.
What type of connections does the SP604R use?
The SP604R uses mechanical copper press connections at both ends.
Why use a reducing coupling?
A reducing coupling provides a compact in-line transition between two different copper tubing sizes.
Is the SP604R a threaded fitting?
No. The SP604R uses press connections rather than threaded connections.
