I purchased a Masterflex Easy-Load II pump head, Model No. 77201-60. It uses L/S tubing 13, 14, 16, 25, 17, and 18. I gather from the many posts in this thread that most folks use L/S 17 tubing. I see also that the longer-life and cheaper alternative to purchasing tubing from Masterflex is to buy Pharmed tubing from U.S. Plastics.

Sounds great. What actual Pharmed tubing product do I buy for the L/S 17 from U.S. Plastics? From a previous post, it was suggested that I order Pharmed 57320, having an interior diameter of 1/4" and an outer diameter of 1/2", with a wall thickness of 1/8". However, it is not clear to me that this is the correct U.S. Plastics tubing that works with an L/S 17-compatible pump head.

Could someone please confirm what specific product I should be ordering for a long-life, Pharmed tubing from U.S. Plastics, to fit my Masterflex Easy-Load II pump head that accommodates LS 17 tubing? Thank you.
