The springs may occur in different colorings. This does not constitute a quality
defect. But make sure that the right spring strength is used. This can be
identified by the spring wire diameter. The „standard version for Novoprene
pump hoses" (Part No. 90P1010) has a diameter of 1.1 mm and the
strengthened version for FPM-, Acidflex- or Masterflex-hoses" (Part No.
90P1015) has a diameter of 1.2 mm.
