Abstract: A push-to-connect coupling with integrated filtration is disclosed. In one aspect, the coupling comprises a tube support, a collet and a filter element. The coupling may include a seal. The coupling connects to a cavity, which may be a portable fitting. The cavity may be a connection on a separate device or system, such as an air tank or other devices. The filter element may be dome-shaped. The tube support is easily assembled with the cavity, for example by threading, to capture the filter element. The tube is connected to the coupling by pushing the tube over the tube support and through the collet. The collet interacts with a reduced diameter section of the cavity to apply a clamping force from the collet on the tube and secure the tube in place. The tube is easily removed from the cavity simply by pushing the collet farther into the cavity to remove the clamping force on the tube, and then pulling the tube out.

Abstract: A vibration isolation system for compactly mounting a vibrating component, such as an air compressor, to an object, such as an air tank, is described. The system may include a rod and bumper system to isolate the vibrations generated by the air compressor from the vehicle or object that it is mounted to. A primary isolation subsystem may include a rod suspension design which consumes significantly less space than existing solutions. The rod is able to achieve equal spring rates in any direction.
