Abstract: An indicator connection adapter device includes a body having a first face, a second face, and a peripheral wall. A primary hole and an offset hole each extend through the body perpendicular to the first face and the second face. The primary hole is centrally positioned on the body. The offset hole is diametrically smaller than the primary hole. The offset hole abuts the primary hole. A set screw is extendable through a set screw aperture for selectively securing an extension of an indicator in the primary hole or a connector of an indicator in the offset hole. Flanges are coupled to and extend outwardly from the second face. The flanges are radially arranged around the primary hole for engaging the body to a collet of a computer numerical control machine.

Abstract: A coupler is provided for coupling a plurality of tubes together. The coupler includes a base member and one or more fittings. Each fitting couples one or more tubes together. The coupler further includes a retainer that secures one or more fittings to the base member.

Abstract: A plug for a port is provided. Preferably, the plug and a cartridge configured to couple fluid tubes to a housing use substantially identical components such as a seal and a retainer or guide.
