A valved fitting is provided which includes a body having a first end and a second end spaced from the first end, with a fluid passage extending through the body between the first and second ends. A valve seat is defined on the body within the fluid passage, and a valve assembly is removably disposed within the fluid passage for controlling flow through the fluid passage. The valve assembly includes a valve head that is engageable with the valve seat in sealable relation therewith. A higher flow area, and thus a higher flow rate, are achieved with the fitting of the invention as compared to conventional fittings which utilize a single-piece body with a Schrader valve, because the valve seat is defined on the body, and the valve head is engageable with the valve seat. Further, the valve assembly is removable, thereby allowing the valve assembly to be replaced when needed. The valved fitting of the invention is particularly useful on a service valve block for an air conditioning system.

High flow valved fitting

A connection apparatus for connection with an inside of a fluid conduit including seal member, sleeve member and collet assembly to seal and grip the fluid conduit which is in fluid communication with a fluid passageway. The connection apparatus further includes a resilient member and a control valve to cause actuating and deactuating relative movement between the collet assembly and the sleeve member so as to grip and seal the inside of the fluid conduit.
