On January 14, 2026, Camozzi Group announced the CARTfit Series 7700, a one-piece push-in cartridge for a tube-to-housing connection. Rather than installing a conventional external fitting, an assembler presses the cartridge into a prepared cavity. The tube then inserts into the cartridge. This is an older announcement, revisited here for its mechanical design and maintenance implications.
CARTfit Series 7700 replaces traditional push-to-connect fittings with a compact press-in cartridge for multiple industries.
What changed at the connection
The connection interface now depends on the housing design itself. Camozzi identifies polymers, brass, and aluminum as suitable cavity materials. The company describes installation with a press tool that seats the cartridge before the tube is inserted. Its announcement emphasizes compact packaging and fewer external connection parts. It does not establish a universal replacement for every existing fitting.
For an OEM designing a new pneumatic manifold, the proposition is straightforward: move the tube connection into the component body. That can help where an external fitting consumes clearance or adds an assembly operation. However, the cavity becomes a controlled manufacturing feature. A housing that lacks the specified geometry cannot be assumed compatible.
The CARTfit Series 7700 is pressed into a machined housing cavity, turning the housing itself into the push-to-connect tube interface.
Engineering checks before specifying it
Start with the exact cartridge variant and manufacturer instructions. Verify the supported tube material and outside diameter for that part number. Specify the cavity dimensions, tolerances, surface condition, and press-tool setup from current OEM documentation. Do not derive them from a photograph or a generic push-in fitting drawing.
Next, define an inspection method for seating depth and housing damage. A low-profile connection can hide an assembly error if there is no visible acceptance criterion. Validate tube insertion, retention, and sealing across the expected pressure and temperature range. Those limits depend on the chosen variant and surrounding housing.
Consider serviceability at the design stage. An integrated cartridge is not the same maintenance proposition as a threaded fitting. Determine whether the cartridge is field-replaceable, what tool access is needed, and how a damaged cavity is handled. These questions matter to maintenance teams even when initial assembly is faster.
The W7700 can be used in specialized medical equipment that implements microfluidics and analytical technology within a confined, unique space.
Where the change matters in automation
Camozzi positions the range for automation, transportation, beverage and cooling, and medical applications. Those are application categories, not approvals for every installation. In an automation cabinet or machine, compact tubing may ease routing near valves and actuators. Its value must be balanced against inspection access, bend radius, labeling, and the ability to isolate a leaking line.
Procurement should treat the cartridge and its matching cavity specification as a pair. Substituting a visually similar part without checking the installation interface creates avoidable risk. Ask for the exact series drawing, assembly procedure, compatible tubing, and qualification evidence for the intended duty.
Installation process for the 7700 series cartridge.
What to validate on a pilot assembly
- Machine trial cavities using the current OEM dimensions and selected housing material.
- Measure seating consistency after pressing and inspect for cracking or distortion.
- Perform leak and tube-retention tests under the site's operating envelope.
- Repeat testing after representative handling and maintenance cycles.
- Document a repair or replacement method before production release.
The manufacturer's announcement verifies the cartridge concept and its intended installation process. It does not replace a model-specific datasheet or site qualification.
