An in-line heater having a heating vessel, defined at least in part by a wall, through which fluid to be heated flows. The wall of the vessel has at least one port formed therein. A fitting, having a body defining a pass-through passageway, is attachable to the port. An end of the body of the fitting has a groove or a ring which mates with a corresponding ring or groove of the port to form a liquid seal between the end of the fitting and the wall of the heating vessel.

1. An in-line heater for high purity fluids, comprising: a heating vessel, defined at least in part by a wall, through which high purity fluid to be heated flows;a port comprising a first aperture formed through the wall of the vessel, a second aperture of greater diameter than the first aperture extending into the wall generally concentric with the first aperture and a ring or groove formed in the wall between the first and second apertures so as to face an open end of the second aperture; anda fitting attached to the port and having a body defining a pass-through passageway, a peripheral outer surface of the body having threads engaging threads of an inner surface of the second aperture of the port and a face of a free end of the body of the fitting having a groove or a ring which mates with the corresponding ring or groove of the port to form a liquid seal between the end of the fitting and the wall of the vessel and a liquid seal between the end of the fitting and the peripheral outer surface of the body to prevent high purity fluid from contacting the threads of the port and fitting. 2. The heater of claim 1, wherein a ring extends from the end of the fitting body and mates with a groove of the port. 3. The heater of claim 1, wherein the port comprises a groove formed in the wall in spaced relation and concentric to the first aperture. 4. The heater of claim 3, wherein a ring extends from the end of the fitting body that substantially mates with the groove. 5. The heater of claim 1, wherein the fitting includes a nut attachable to a second end of the fitting body for securing a tube to the fitting. 6. The heater of claim 5, wherein the nut and second end of the fitting body are threadedly connected to one another. 7. The heater of claim 5, wherein an outer surface of the second end of the fitting body and an inner surface of the nut are configured to cooperatively engage the tube therebetween. 8. The heater of claim 5, wherein the nut includes a compression connector that compresses against the tube as the nut is attached to the second end of the fitting body. 9. The heater of claim 1, wherein the fitting includes a stop extending from the body intermediate the ends thereof that contacts an exterior surface of the wall to prevent further insertion of the fitting into the port of the wall. 10. The heater of claim 1, wherein the fitting includes a stop extending from the body intermediate the ends thereof that contacts an exterior surface of the wall to prevent further insertion of the fitting into the port of the wall. 11. The heater of claim 1, wherein a portion of the outer surface of the fitting intermediate the ends thereof is multi-faceted to provide an engageable surface with an attaching or removing tool. 12. The heater of claim 1, wherein a portion of the outer surface of the fitting intermediate the ends thereof is multi-faceted to provide an engageable surface for an attaching or removing tool. 13. An in-line heater for high purity fluids, comprising: a heating vessel, defined at least in part by a wall, through which high purity fluid to be heated flows;a port formed in the wall of the vessel comprising a first aperture extending through the wall, a groove formed in the wall in spaced and concentric relation to the first aperture and a second aperture having a greater diameter than the first aperture and the groove and extending from an exterior surface of the wall so as to be generally concentric with the groove and the first aperture;a fitting attached to the port and having a body defining a pass-through passageway, the body having an outer surface having threads which threadedly attach to internal threads of the second aperture of the port, a free end of the body of the fitting having a ring protruding therefrom which mates with the groove of the port to form a liquid seal between the end of the fitting and the wall of the vessel, and the end of the fitting and the outer surface of the body to prevent high purity fluid from contacting the threads of the body and port; anda nut attachable to a second end of the fitting body for securing a tube to the fitting. 14. The heater of claim 13, wherein the nut and second end of the fitting body are threadedly connected to one another. 15. The heater of claim 13, wherein an outer surface of the second end of the fitting body and an inner surface of the nut are configured to cooperatively engage the tube therebetween. 16. The heater of claim 13, wherein the nut includes a compression connector that compresses against the tube as the nut is attached to the second end of the fitting body.
