Will this fitting work to connect a cobalt mj1200 to 1/2" hard tubing?
Question by: Carol on Jul 24, 2016, 12:45 PM
Hi there,
The MJ1200 will connect to the ½” x ½” push connect union (sku 100002) that I have in the link below. The output of the MJ1200 is the same OD as ½” push-connect tubing.
Thanks for the question and if you have any more just let us know.

Will this connect 1/2" OD vinyl tubing to 3/8" OD vinyl tubing?

Great question!
The Mur Lok fittings are designed to work with the Hard RO tubing vs the soft vinyl tubing. Feel free to let us know if you have any further questions!
