Air Tightness Testing Device

This is a 3D model of an air-tight equipment device, mainly used to conduct air-tightness experiments on a cast cylinder body after processing. It completes the test through positioning and sealing with four directional cylinders. The model is detailed in design, with a clear structure, comprehensive documentation, and is in STEP neutral format. It can be opened and edited by any common 3D software and can be used as a reference template for similar design solutions. You are welcome to download and use it.
