3/8-19 BSPT Taper Pipe Tap

• HSS
• Ground Thread
• Bright Finish
• BSPT (British Standard Taper Pipe) – 55° Thread Form
• This thread is tapered, but with an ‘interference’ fit. Unlike BSP, it needs no seals or gasket – pressure tight joints are achieved by the thread alone
• Pipe taps are the nominal size of the pipe fitting and not the actual size of the tap
