Graham-Field 3931 14 GF Health Natural Rubber Latex Surgical Tube, 1/8" Inner Diameter, 1/4" Outer Diameter, 50' Roll

I ordered the tubing for a physics project, which is the end of the year "catapult project". In the past we have tested heavier types, even the heavy black one, but this was very durable and light. I first thought it was very light and may not withstand the forces and snap, but it was just the opposite. It is very durable, and has great flexibility. I did not use it for medical purposes so I could not comment on such usage. Great product overall, and compared to the medical supply stores, the price is unbeatable.

Used tube for scientific purpose. The product is flexible and durable. Will by again when heed it.

Worked great for our application - a bungee for our high jump pit.

I suspect that this is not an authentic product made by Graham-Field or perhaps they have switched to a low cost Chinese manufacturer. Either way, the quality isn't the same as the roll we purchased about 5 years ago.

Perfect rubber tubing for a F3L (F3RES) model sailplane high start. Does come in two pieces, so have a joiner (a piece of allthread with an acorn nut on each end, and a couple zip ties) ready. Arrived on time and well packaged. Tubing was fresh and not old. Best price and lead time around.

Works for Slimgshots! Face it, you know that there is nothing "surgical" that you are using this for... you're going to build a sling shot. :) For that purpose, we used it for our Trail Life Troop. It was good, durable, cheap and gave that nice snap that makes the rocks fly. It looses one star for two reasons, first, it is very "slick" so it required a bit more securing to the wood then other tubing I have used (there is 0 "tackiness" so it slid right out of the binding). Also, when pulled back to pull tension, there seemed to be a point at which you could keep pulling back but would not get any more power out of the tubing. But if you have a bunch of 6-12 yearolds and some Y shaped branches... this is what you want to order. Have fun! :)

While this is not very thick tubing, it is functional. We used on a school model catapult project and my son won the award for longest launch (other students used bungee cords). We used 4 loops for strength/force and that worked great. I think this would also work well for balloon launcher although I would probably use at least double loop of the tubing for a balloon launcher since the tubing is a bit thin. Overall great value.

It is not 1 continuous piece. I ordered a 100ft to get a 100 ft length of tubing not three pieces tapped together to make 100ft.

Was three pieces spliced together. Lots of waste for my project because of the lengths. Couldn’t finish project. Wish I read the reviews to see others had the same problem.

exactly as advertised

good item
