Multi-port adaptors are useful for adding power, thermocouple, liquid nitrogen and other feedthroughs to existing (usually larger) flanges. These adaptors can also be devised to provide outboard support for things like rotary and / or linear motion feedthroughs so the motion can be delivered where it is actually needed. The “standard” support tube is 31.8mm (1.25”) OD with pumpout holes, slots for wires and LN2 lines and a removable adaptor with ball bearing (usually 9.5mm (0.375”) ID).
Many different configurations are available, including different size flanges, different numbers of flanges and radial spacing of the smaller flanges. The most common size uses DN40CF flanges on the top and bottom with four off DN16CF flanges around the body. Zero-length adaptor flanges can be used to mate the multi-port adapters to other flanges. Alternative flange configurations and lengths are available, please contact sales office for further details. Support tubes are also available in many different configurations of flange size, tube diameter and length etc. A schematic diagram below shows the general appearance of the support tube. Please contact our sales office to discuss your specific requirements for support tube.
