Overview: The document provides technical specifications for Spacers Form F (PN 10), which are flexible up to the last millimeter and recommended for lengths up to 20 mm. These spacers are made of solid PTFE and are available in various sizes and materials.

Specifications: The spacers are available in different diameters (DN) ranging from 15 to 500 mm, with lengths between 10 to 25 mm. The document includes a detailed table listing the external diameter of the pipe (d1), internal diameter (d2), external diameter (d8), and approximate weight per meter for each size.

Materials: Spacers are made from PTFE, available in virgin or conductive forms, and PP for diameters up to DN 300. Additional pressure rates include PN 16, PN 25, and PN 40.

Special Features: Options include spacers with reinforcement rings and filled PTFE. Declined spacers with various degrees are also available.

Standards and Limitations: Construction dimensions for DN 15 and DN 450 are not defined in DIN 2848. Vacuum resistance varies with temperature, with full vacuum resistance at 23°C, limited at 100°C, and no vacuum resistance at 230°C.

Recommendations: For diameters not listed, refer to the next nominal diameter. Standard lengths are available from stock.
