FAQs
What tubing materials are used in medical device and healthcare applications?
The most common materials for medical tubing are silicone, TPV, PVC, and fluoropolymers including FEP and PFA. Silicone is preferred for implantable and body-contact applications due to its biocompatibility and wide temperature range. TPV is specified when halogen-free, oil-resistant, or flexible materials are required. Medical-grade PVC remains widely used for fluid transfer, drainage, and IV applications. FEP and PFA are used where chemical resistance and clarity are both required. Grayline LLC offers biocompatible, non-phthalate formulations across all major material families, with material traceability available for regulated applications.
Can I get custom-sized medical grade tubing in small validation quantities?
Yes. Grayline LLC manufactures tubing to custom inside diameter, outside diameter, and wall thickness for medical applications. Short validation quantities are welcome — Grayline serves both development runs and high-volume production from the same manufacturing operation. Custom color coding and in-line printing are available for identification and traceability requirements. Contact the engineering team with your application details for a Free Spec Review.
Is Grayline tubing USP Class VI or FDA compliant?
Yes. All Grayline LLC tubing products are non-DEHP. For applications with stricter requirements, Grayline offers non-phthalate tubing certified to contain no more than 1,000 ppm total phthalate content, as well as phthalate-free options using non-PVC materials. These are increasingly required for medical devices, pediatric applications, and products sold in the EU under RoHS3. Contact the engineering team to confirm which formulation is appropriate for your regulatory requirements.
Does Grayline offer non-phthalate or DEHP-free medical tubing?
Yes. All Grayline LLC tubing products are non-DEHP. For applications with stricter requirements, Grayline offers non-phthalate tubing certified to contain no more than 1,000 ppm total phthalate content, as well as phthalate-free options using non-PVC materials. These are increasingly required for medical devices, pediatric applications, and products sold in the EU under RoHS3. Contact the engineering team to confirm which formulation is appropriate for your regulatory requirements.
What sterilization methods are compatible with Grayline medical tubing?
Grayline LLC offers medical tubing compatible with the three primary sterilization methods used in healthcare: gamma radiation, ethylene oxide (EtO), and autoclave. Material selection determines sterilization compatibility — silicone and certain TPV formulations handle all three methods well, while PVC is typically limited to EtO. If your application involves repeated sterilization cycles, the engineering team can recommend the appropriate material and confirm compatibility with your specific sterilization protocol.
Is Grayline LLC the same as Grayline Medical?
No. Grayline LLC is a polymer tubing manufacturer based in Waukesha, Wisconsin, in business since 1966. Grayline LLC serves automotive, appliance, and medical device manufacturers with custom flexible tubing and heat shrink products. If you are looking for Grayline Medical equipment sourcing, that is a separate company with no relation to Grayline LLC.
