One is Parallel threads or we can say Straight threads. The second one is the Taper Thread. BSP is BRITISH STANDARD PIPE THREAD Also known as Whitworth 55° Thread Form. BSPT is BRITISH STANDARD PIPE TAPER THREAD Thread form per AS 1722.1, BS 21, ISO 7. BSPP is BRITISH STANDARD PIPE PARALLEL THREAD Thread form per AS 1722.2, ISO 228. How to Model NPT Threads in Solidworks Hardware Oct 01, 2020 · Use the table below to define the thread profile, this includes:Pitch, P:Corresponding to the Threads per Inch of the given pipe, e.g. this 1-1/2 NPT Pipe Size at 11-1/2 Threads per Inch will have a pitch of 1÷11-1/2 or .087. Height of Sharp V Thread, H:Height of fundamental triangle created be thread Hydraulic Fitting Thread Chart Hydraulics DirectAmerican Connections National Pipe Tapered Fuel (NPTF) The male and female threads connect and a seal is formed when the two are mated together (i.e. threads deformation). This is known as a dry seal thread. If additional sealing is required, teflon and pipe dope can be applied. The National Fluid Power Association (NFPA) does not recommend the connection for hydraulic applications, however it
