connecting different tubing together

Samper · 10-24-2007, 07:40 PM

I have some very flexible 1/8" OD tubing that goes to a peristaltic pump that I need to connect to some 1/4" OD water line. The 1/8" will fit tightly inside of the 1/4" but under pressure this fit doesn't mean much. Does anyone have any ideas how to go about connecting them? I've looked around for an hour and can't seem to find the proper equipment.

Is the tubing "stretchy" enough to fit over some rigid 1/4" tubing? Then you could attach both to the tubing, and secure with a zip tie.

No I don't believe that it is. Don suggested going to an auto parts store so I'll give that a try tomorrow.

Something like this or close to it.

You could use a John Guest adapter. Make sure that each end is the appropriate size to accept the two different diameters of tubing. Just shove them in and they're connected.

If you can show me a John Guest adaptor that goes from 1/8" OD to 1/4" OD or even reducers to somehow get me there in two pieces I'll take em.

You cant use JG for peri pump rubber hose, it doesnt work. The fitting I posted is a apt peri pump adapter. You can get close to the same at most auto parts stores but it will be black.

I went to three auto parts stores today, also Lowes, Ace and Home Depot and no one around here has anything similar. Do you have a part number on that Don?

DonW · 10-25-2007, 10:23 PM

No I just buy them bulk and or in small assortments. Schucks and autozone carry a product line named Help. There will be and assortment pack.
Schucks even carries dayco.
