FAQ
What is the smallest internal diameter (ID) you can produce?
• In PVC & EVA, the smallest ID consistently is currently, .003".
For PE, it would be .015".
Why is my price higher if I want a part cut to length opposed to having
it coiled?
• With cut lengths, there is more time involved in packaging the product,
plus depending on the tolerance of the cut length, we may not be able to run
the extrusion line as fast.
What materials do you offer in non-DEHP?
• PU, DOA, PE, TPE, Natvar BioPath ™, and Natvar 252 ™
What is your minimum order?
• $500 Lot Charge for straight PVC (when raw material is in stock).
What is your lead time?
• Shipment in 2 weeks (when raw material is in stock). We also offer
Kanban/stocking programs to meet JIT delivery requirements.
Do you have samples?
• We do not inventory small samples due to shelf life and limited
storage space. We do keep some specialty items for promotional purposes
that can be shipped upon request. These include, but are not limited to:
Natvar PowerPath ™, Natvar SurePath 151 ™, Natvar SurePath 252
™, Natvar BioPath ™, Natvar SR Tubing, Bubble or Transition
Tubing, Cardiovascular Tubing, IV Tubing, Microbore Tubing, Multi-Lumen
Tubing, Solvent and Thermal Bonded Paratubing, Custom Printed Tubing,
Co-Extruded Striped Tubing, and ID or OD Profile Extrusions. Samples can
also be taken from current orders being produced at the time of your request,
should they meet your requirements. Contact a Customer Service Representative
for more information.
What size ranges do you offer?
• We can produce tubing with an ID range of 0.003" to 2.000"
and an OD range of 0.020" to 2.500". Size ranges may vary depending
on material selected. Please consult with Natvar Engineering when considering
tubing size for your application.
What cut length tolerances can Natvar hold on PVC?
• Cut length tolerance will depend on the length of the cut piece
of tubing. For tubing length less than 1 ft., Natvar can hold as tight as
+/- 0.032". Tolerances may vary based on size, material type, and cut
length, so please consult Natvar Engineering for cut length tolerances specific
to your application.
What range of durometers do you offer in PVC?
• 45A to 98A
Does your company offer Gamma Stable compounds (Radiation Grade)?
• Yes These compounds are slightly more expensive in most cases and
tend to have more tint to the color
Do you offer engineering support on new products?
• Yes, we have state of the art development labs for your most
challenging projects
Do you extrude multi-lumen tubing?
• Yes, up to 8 fluid paths and ranging form 4 French to 10 French
