FAQs
What tubing materials are recommended for household and commercial appliance manufacturing?
PVC is the most common material for appliance tubing due to its chemical resistance, flexibility, and cost efficiency. TPV is specified when halogen-free or oil-resistant materials are required. Polyurethane and TPE are used in applications requiring superior abrasion resistance or flexibility across wide temperature ranges. For applications involving direct contact with water or cleaning agents, Grayline offers RoHS-compliant formulations tested against harsh detergents and chemicals common in dishwashers, washing machines, and commercial equipment.
What tubing specifications are required for appliance safety and UL compliance?
Appliance tubing commonly needs to meet UL 94 V-0 (flammability rating for heat shrink and insulation) and UL 224 (extruded insulating tubing). These ratings confirm the material self-extinguishes and meets dielectric strength requirements for electrical insulation in appliances. Grayline tubing listed under UL 224 is tested and certified — UL/CSA marks appear on package labels. If your application requires a specific flammability or voltage rating, Grayline's engineering team can confirm which products qualify.
Can I get custom-sized tubing for a specific appliance component or OEM requirement?
Yes. Grayline manufactures tubing to custom inside diameter, outside diameter, and wall thickness outside of standard stock sizes. Custom color matching is available for both aesthetic and functional identification requirements. Grayline has an established supply history with Whirlpool tier-1 suppliers and supports Whirlpool, LG, GE Appliances, and Electrolux OEM specification families.

Does Grayline tubing meet UL 94 V-0, UL 224, or major appliance OEM specifications?
Yes. Grayline tubing meets UL 94 V-0 flammability requirements and UL 224 extruded insulating tubing standards. RoHS-compliant materials are available across the product line. Grayline also supports OEM specification families for Whirlpool, LG, GE Appliances, and Electrolux. For applications referencing a specific OEM spec family, the engineering team can confirm compliance and provide material documentation.
How does Grayline support appliance manufacturers from design through production?
