Specialty Bends - Plastic Tubing

Transparent Thermoplastic Butyrate & Provista PETG

Extruded Provista Tubing (PETG) Coated ACS StaticideWe make helices, U bends, offset snake bends, candy cane bends and all in between.

Our technique has been evolving for over 60 years, and we consider our bend makers artisans in their trade.

If you need a plastics tube or pipe bend, we can provide it between .5"OD to 10"OD, any angle up to 180 degrees and any radius up to 110."

We have been making bends for The Roasting Plant as they build new and upgrade existing restaurants.

They, and their engineers from Advanced Design (FL) have tight tolerances and every bend is different. We extrude Provista tubing (PETG) and coat it with our ACS Staticide.


We frequently are asked to make U bends (180°) bends. In a U bend, the offset is twice the radius, and keeping the offset is the trick. In thermoplastics bends, the tubing tends to pull in or out (memory) and work as a thermometer with radiant heat. Our process minimizes movement of the bend offset.

Here is one of our Ubends, still on the cooling rack.

Puck Conveyors U Bend Plastic Tube

Here is a U bend at use in a test machine
for puck conveyance.


Pictured below is a recent tight-radius bend. Here we have a CAB (butyrate) tube, 6" OD x 5.625" ID 180° on a very tight 16" Center Line Radius. We will remove the tangents before shipping. We have the ability to maintain clarity and reduce ovality to a minimum on these bends.

Do you need an offset bend? If you do, simply provide for us a triangle. Tell us the vertical offset that you need, and the distance between your connection points. You can even specify the tangent. For example, if you wanted a 26" vertical offset with a distance of 60" and you wanted tangents of 10" and 7" we would provide you the offset based on longest possible radius.

P Trap Bends

We made these P traps for HVAC equipment. The plastics tubing will replace copper tubing. We color some of them also.

Candy Cane Bend

A conveyance company occasionally orders candy-cane bends.
It takes a certain technique to make this kind of bend and to avoid the stresses that would generally pull the bend upon itself. Additionally, bends of all types, but especially this type act as thermometers moving with temperature changes (and especially to radiant heat).

Colored Bends

One of our cup manufacture customers got creative. Their factory was getting congested by an array of clear pneumatic tubing to the point where they could not visibly detect one cup line from the other. Their engineer wanted an easy way to distinguish the lines visibly and asked for colors. We obliged. The tubing pictured to the right was coated with a colorant that adheres, or rather embeds into the tubing for a permanent colorant. It only embeds to the outside wall so it has no effect on the cup or any FDA or NSF compliance.
