Compare to part number HC252, HC 252, HC-252, H.C. 252 (07HC-252-011). This HCHT250ST tip is a patent-pending long-life version of our standard HCHT250 tip. Both are otherwise identical in form, fit, and function. 1/4 inch tube diameter, 2.054 inch overall length. Orifice diameter Ø0.031" Mid-height heater cable connection. Knurled compression tube fitting (common Swagelok double-ferrule type). Intended to be finger-tightened only onto a bulkhead or other male fitting to allow for future removal and replacement. Over-tightening, made more likely when using a wrench, especially when exposed to elevated temperatures during operation, can lead to galling or seizing at the mating surfaces, potentially making removal difficult. Internal patented low work function insert (Pat. No. 10,002,738).
