Tygon tubing size confirmation

[Breadman03]

I measured the tubing in my peristaltic pump with a caliper and came up with these approximate measurements due to the pliability of the tubing making it a little difficult to know when I made contact and the tubing being used and possibly slightly deformed.

OD-0.26"/6.67mm
ID-0.124'/3.15mm

This seems to me like it is 1/4" OD x 1/8" ID tubing such as can be found here as the fourth result.

Does that sound accurate to you as well? Thanks!

@jda any ideas on calrx pump tubing?

What peristaltic pump are you using and if it supports different pump heads, which model? Also, many pump heads like Cole-Parmer (Masterflex) can take multiple tube sizes.

I’m actually using the DOS. My Watson Marlow started acting up, so I made the switch. I suspect my humid basement caused electrical issues.

I think your measurements are correct, DOS pump heads use 1/4" OD, 1/8" ID tubing.
