Can the Quick connector DN5.5 without valve, threaded, nickel-plated steel, series 1400KA / 1423KA be used with BSPP or BSPT fittings interchangeably?

Quick connector DN5.5 without valve, threaded, nickel-plated steel, series 1400KA / 1423KA cannot be used interchangeably with BSPP and BSPT fittings. The product is offered with either external BSPT (tapered) thread or internal BSPP (parallel) thread; these thread types have different geometries and sealing methods (BSPT seals by thread taper, BSPP requires a gasket or O-ring). Mixing them risks poor fit, leaks, or damage. Always match the connectorâs specified thread type (BSPT or BSPP) to the mating fitting or use a proper adapter designed for converting between BSPT and BSPP.
