Flexible silicon tubing for making squeeze seals between insemination tips and the syringe. This tube has a 1mm internal diameter and a thick wall for making a secure compression seal.
This is used when joining the Insemination tip to the syringe holder. The tip is inserted into the holder end with a short length of squeeze seal. When the syringe holder end is tightened it compresses the seal against the syringe body tip and around the insemination tip. This makes a tight seal between the insemination tip and syringe. This section of squeeze seal should be replaced often. It can be sterilised between use but will degrade over time.
