The passage through which biopsy, haemostasis and foreign-body retrieval instruments travel into the body via the endoscope channel. Of all endoscope parts, this is where friction and durability are felt most directly in the hand.
Bore, length and layer structure are built to drawing. In the same category, see the Endoscope Insertion Tube and Viton Bending Rubber as well.
The bore is extruded low-friction for forceps and instrument passage. If you have a friction coefficient or passage test condition, we build it into the spec.
Yes. Tell us the minimum bending radius (e.g. 10R) that must stay kink-free and we match wall and material.
Yes. TDS · MSDS come with every specification reply. ISO 10993 biocompatibility data varies by grade and lot, so we confirm it with the factory (Linstant) and reply.
Standard sizes start with small sample lots. MOQ and lead time depend on dimensions, material and secondary processing — send OD · ID · wall · tolerance · length · quantity and we reply within one business day.
Dimensions, material, application. Those three are enough to start. A drawing makes it faster. We reply with TDS, MSDS and MOQ together.
