TOFLE PTFE hoses are manufactured using PTFE powder with authorization from UL94-V0.

The UL standards are exemplary global safety standards for electrical equipment, established and approved by UNDERWRITERS LABORATORIES INC. in the United States. This standards are applied to products in various fields, such as electrical products, fire prevention devices, plastic materials, lithium batteries, and electric vehicle related equipment. The UL standards are classified into three major categories: flammability (flame retardance), flame resistance, and electrical properties. The UL94 category consists of “plastic flammability tests for devices, apparatuses and parts”, including horizontal and vertical burning tests.
