ND8 Silcone cream/PTFE red UltraClean, black, 5,5 mm hole, 8-425 threat, 55° shore A, 1,5 mm, 10x100 pc/PAK

Silicone/PTFE Seals

• Temperature resistant from -60°,C up to 200°,C

• Silicone liners with PTFE on both sides for less coring

• Different hardness (durometers) to meet requirements of the various types of needles regarding penetration

• Much cleaner than Natural Rubber, RedRubber or Butyl

• The special, slitted liner for VWR (Merck®,)/Hitachi is only available unassembled, as the diameter with the most optimal valve effect does not achieve any pressfit in the cap. Enlargement of the diameter is only possible with negative effects on the building up of vacuums in the vial
