Mur-lok fitting information
Mur-lok® Polypropylene Fittings have a dual o-ring design at each tube connection, giving end users confidence in their fitting connections.

All Mur-lok® fittings are constructed of FDA approved materials and are suitable for food contact.

Fitting Features:
  • Leak Resistant Dual EPDM O-rings
  • Chemical Resistant Polypropylene
  • 150 p.s.i. @ 70°F (10 Bar @ 20°C)
  • 60 p.s.i. @ 140°F (4 Bar @ 60°C)
  • For use with 1/2" RO Tubing
How to make a connection
  • Cut tube square
    It is essential that the outside diameter be free of score marks and that burrs and sharp edges be removed before inserting into fitting. For soft or thin walled plastic tubing we recommend the use of a tube insert.
  • Insert tube
    Fitting grips before it seals. Ensure tube is pushed in to the tube stop.
  • Push up to tube stop
    Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position while the "O" ring provides a permanent leak proof seal.
  • Pull to check secure
    Pull on the tube to check it is secure. It is good practice to test the system prior to leaving site and/or before use.
Push in Collet and remove tube

To disconnect, ensure the system is depressurized before removing fitting. Push in collet squarely against face of fitting. With the Collet held in this position, the tube can be removed. The fitting can then be re-used.

Mur-Lok fitting 1/2"

This is what I needed to install a carbon & GFO Reactor on My reef aquarium, others don't seem to have the same quality and I like the dual O-ring design for leak resistance.
