Can the ISO-B quick connector plug with GW (1/8" Ã· 1") in galvanized steel, HANSEN, type HK be used with both BSP and NPT internal threads without leaking?

Short answer: No . you should not mix BSP and NPT internal threads on the same ISO-B quick connector plug. Explanation: The ISO-B quick connector plug with GW (1/8" Ã· 1") in galvanized steel, HANSEN, type HK is offered with internal BSP or internal NPT thread options, but BSP (parallel) and NPT (tapered) thread forms are different standards and are not compatible with each other. Using a BSP male thread in an NPT female thread (or vice versa) will not produce a reliable metal-to-metal or thread-seal fit and will very likely leak. Proper sealing would require the correct matching thread type plus appropriate sealing method (thread sealant, tape, or a sealing face where specified). Recommendation: Match the connectorâs internal thread option exactly to the mating male thread (BSP-to-BSP or NPT-to-NPT). For applications with pulsating pressure, follow the product guidance to reduce maximum working pressure by 50% when disconnected.

Is the ISO-B quick connector plug with GW (1/8" Ã· 1") in galvanized steel, HANSEN, type HK suitable for use with both BSP and NPT internal threads without adapters?

Yes. The ISO-B quick connector plug with GW (1/8" Ã· 1") in galvanized steel, HANSEN, type HK is offered with internal BSP or NPT threads and is compliant with ISO 7241-1 B, so it can be fitted to either BSP or NPT internal threaded counterparts only if the coupling variant you select specifically has the matching internal thread type. BSP and NPT are different thread standards and are not directly interchangeable without adapters. Choose the HK version specified as BSP for BSP systems or the HK version specified as NPT for NPT systems; otherwise use an adapter.

Does the ISO-B quick connector plug with GW (1/8" Ã· 1") in galvanized steel, HANSEN, type HK require thread sealant for BSP vs NPT connections?

ISO-B quick connector plug with GW (1/8" Ã· 1") in galvanized steel, HANSEN, type HK: If the coupling has BSP (British Standard Pipe) parallel thread (BSPP), a proper sealing method is required. typically a bonded washer, Oâring, or thread sealant/tape depending on the specific fitting design. Many ISO quick couplings with internal BSPP threads rely on an internal Oâring for hydraulic sealing, so additional thread sealant is not required and should be avoided if the manufacturer specifies an Oâring seal. If the coupling has NPT (National Pipe Taper) threads, sealing is achieved by the metalâtoâmetal taper plus pipe sealant (PTFE tape or pipeâdope) to ensure a pressureâtight joint; therefore a compatible thread sealant is required for NPT connections. Conclusion: Use sealant for NPT threads. For BSP threads, follow the HANSEN type HK specificationâif the coupling uses an internal Oâring/bonded washer, do not use thread sealant; if it is BSPP without an internal seal, use an appropriate thread sealant. Always verify the specific part configuration and manufacturer recommendations before assembly.

Additional information

Material	CS – steel (cast iron)

HANSEN type HK quick coupling with internal BSP or NPT thread. Compliant with ISO 7241-1 B standard. Quick couplings designed and manufactured in accordance with the PED 2014/68/EU directive. Quick couplings in sizes from 1/2” to 1” are made of special hardened steel, providing increased resistance to pressure pulsations. In the case of pulsating pressure with the coupling disconnected, the maximum working pressure should be reduced by 50%. Can be used interchangeably with ISO-B quick couplings from other manufacturers. Application: hydraulic power (hydraulic oil), industrial (water, steam, fuels and oils, gases, chemicals). Material: galvanized steel. Sealing: NBR (operating temperature from -40°C to +121°C), EPDM (operating temperature from -54°C to +149°C), viton (operating temperature from -29°C to +204°C). Working pressure: up to 345 bar (depending on the size of the quick coupling). Flow has been provided for a pressure drop of 3 bar.
