With silicone / PTFE septa
Screw seals ND13 are made of PP and have a 13-425 thread. They have a 8.5 mm centre hole or are closed. Screw seals are supplied with fitted septa made of a variety of materials or without any septa.
These septa are temperature-resistant from -60 °C to 200 °C and have better purity than septa made of natural rubber, butyl or RedRubber. However, they have less effective resealability properties and are therefore more suitable for single-injection applications.
Septa with a double-sided PTFE coating show a very low particle formation during penetration.
