Mur-lok Reverse Osmosis 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 BRS reverse osmosis systems and BRS media reactors. These high quality American made fittings are constructed with FDA approved materials.

Product Questions

what size hole is recomended to drill inorder to insert the male NPT fitting
Question by: Stratos Kantounis on Nov 21, 2023, 6:55 PM
We would recommend using a step bit to gradually increase the hole size to get it to the correct opening.

What size do I need so I can upgrade my BRS reactor to the sicce 1.5 from the maxi jet?
Question by: Robert Copeland on Apr 18, 2020, 2:47 PM
Hi Robert,

You will need the 1/2" NPT x 1/2" Push Connect fitting to adapt your Sicce 1.5 for use with the BRS reactor.

I hope this helps!
Happy Reefing

Do you have these in 90 degree like the dual reactor? I'm trying to separate the dual reactor to make two single reactors.
Question by: Daniel Smith on Aug 5, 2019, 8:38 PM
Hey there!

We use two fittings to make the 90 degree bend. I will attach the links for both https://www.bulkreefsupply.com/mur-lok-ro-elbow-stem-x-push-connect.html

Will these fit onto a Schedule 40 female fitting?
Question by: Edward Hajek on Mar 26, 2017, 5:23 PM
Hey there,
So long as the female fitting has standard NPT threads of the appropriate size, then these should work just fine.

Have a great day!

Witch size would I need for the Brs PO4 reactor ?
Question by: Ramon on Jul 27, 2016, 12:23 PM
Hi there,
The BRS Reactors have ½” NPT x ½” Push Connect fittings that convert the threads on the canister head to push connect tubing. For white you will want SKU 100003. If you have any more questions just let us know. Thanks!
