Where can you still buy Rubber Colon/Rectal Tubes

Does anyone know where you can still purchase rubber colon/rectal tubes (close end) longer that 50cm (20 inches)?

I spent at least 3 days of my life searching the internet for longer ones, but the standard length seem to be limited to no more that 50 cm, which are readily available for domestic use through Amazon and a few other suppliers.

Yes, there are retailers (almost exclusively in India) that do produce and supply longer ones in varying Fr sizes, but they expect me to purchase a minimum quantity of 500 pieces before they fill the order. Although, very cheep per unit when compared to Amazon (unit + postage to Australia), I don't need that many. I will not live long enough to use them all.

Sure, check out E-Bay...they've got all kinds of longer tubes. Hopefully you'll find what you want.

Here I bought rubber colon tubes in different diameters, 75 cm long.

Apparently the item is being phased out as there are only 8mm calibers left.

As far as I know, this shop delivers worldwide.

You can buy them on Amazon as well. Ebay or Ali Express have them but you may need to wait longer for them to be shipped from China but definitely less expensive on Ali Express
