John Guest double reducing union
Straight fitting to join two tubes of different diameters in the same line using push-fit connections.
Configurations
The variants include 3/8" to 3/16", 1/4" or 5/16", 5/16" to 3/16" and 1/2" to 3/8".
When to use it
It is suitable when the run continues in a straight line but needs to change diameter.
Installation
Identify each side, cut the tubes square and insert them fully. Do not use an approximate size or force the tube.
Frequently asked questions
Is it the same as a straight union?
No; it connects different diameters.
Does it change the direction?
No, it is a straight coupling.
What should I measure?
Both outside diameters.
Can I physically reverse the direction?
The joining function does not depend on a flow direction, but each tube must go into the side for its own size.
