Mur-lok RO fittings are the only RO fittings that feature dual EPDM O-rings to ensure a straight leak free fit. We believe GA Murdock Mur-lok fittings to be the best so strongly that we use them virtually exclusively on each of our BulkReefSupply.com reverse osmosis and BRS media reactors. These high quality American made fittings are constructed with FDA approved materials.

Product Questions

can we use this in dos for ro line
Question by: SHRIVATHSA SHRIVATHSA on Sep 8, 2020, 11:26 PM
Hey there,
Thank you for reaching out to us! This will not fit on the DOS, but the DOS does take RO tubing without any adaptations.

Please let me know if you need anything further and take care!

Will these work to attach tubing to the DOS?
Question by: Jody C Voissem on Feb 9, 2019, 5:15 PM
Thanks for reaching out to us! Mur-lok push connect fittings are not directly compatible with Apex DOS tubing, and may allow air into the lines.

Let us know if you have other questions.
