Thermoformed tubing assemblies from Diba Industries can be custom designed with bends and coils that are said to fit into instruments, preventing kinking and improper installation for problem-free processing. The tubing design creates a one way fit, ensuring that assemblies can only be installed in the correct direction. The ends of the thermoformed fluoropolymer tubing are flared using a proprietary thermal forming technique and backed with a washer and threaded bottom seal fitting to create a leak tight seal. Thermoformed tubing can be configured in any shape needed.
