Prekė gali skirtis nuo prekės, parodytos nuotraukoje

 

Temperature resistant from -40°C up to 120°C. Natural Rubber is ideal for multiple injections due to high resealability, but not as easy to penetrate than RedRubber/PTFE. RedRubber/PTFE has a better purity than Natural Rubber/TEF, is softer and has less fragmentation, but doesn't offer the outstanding resealability as Natural Rubber/TEF. Further Screw Seal ND8 with closed/open top resp. with white Caps are available upon request!
