MasterFlex Tubing

[nezw0001]

I have been running a MasterFlex pump with tubing L/S 24 tubing I bought off of ebay. My problem is the tubing cracks inside the head and starts leaking about every 6 weeks. What type of tubing should I be buying? I understand the sizing piece just not what material I should be using.

You want pharmed tubing. From my experience it last the longest. Some of my pharmed tubing is several years old. obviously this will depend on your usage.
