The blue Push-On caps made of PE have a thinned penetration point, but no additional septum. They are an inexpensive alternative to crimp caps for non-critical applications.
The transparent PE caps are 9 x 5.9 mm and have a 4 mm centre hole.
Septa made of natural rubber are temperature-resistant from -40 °C to 120 °C and ideal for multiple injections thanks to their excellent resealability properties.
