Features: NPSF (Dryseal) - National Pipe Straight Fuel; A variation of the Dryseal thread is the NPSF. It is used for internal threads and an NPTF external thread can be screwed into it to provide both a satisfactory mechanical connection and hydraulic seal. ; A combination of a parallel and tapered thread would not appear to be ideal but it is widely used. ; Many quick disconnect couplers for example have the NPSF thread and are recommended by the manufacturer for use with NPT and NPTF. ; BOTTOMING TAPS have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole. Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap. ; Specifications:Diameter1/4"Pitch18 tpiLeadBottomingOverall Length67 mmTapping Drill11.2 mm
