Duotight Food Grade Plastic (Push-In) Fitting - 3/8" Male NPT X 5/16" (8mm)
Enjoy the benefits of a reliable seal with the dual internal EPDM O-rings on this Duotight Food Grade Plastic Push-In Fitting. The one end is a 3/8" MNPT connection and use the other end to push in your 5/16" OD (8mm) EVABarrier Polyethylene Tubing.
Before pushing in your tubing, it is recommended that it has been cut straight so that a complete seal is made. Once this has been done, you will safely be able to move your liquids at a pressure of 60 PSI or less.
