- Notes: BSPP (parallel) is the most common variant. Specify BSPP vs BSPT on the RFQ.
Family context
Stainless-steel and brass thread reducers convert between BSP, NPT, and NPSM thread standards on instrument lines, sample lines, and low-pressure transfer assemblies. Used as inline adapters where the pipe-thread standard differs from the host-equipment standard.
How to order
Specify (a) the size, (b) the body material from the available options, and (c) any special seal / gasket requirements. Indus engineering will confirm the exact Sealfast part number on the RFQ. For Bauer couplings, specify the Bauer-standard size code (2", 3", 4", 5", 6", 8") and end configuration. For Dry Disconnect, specify the seal compound (Viton FKM for petroleum / fuel; PTFE for aggressive chemical) — selection drives the part number.
