Is the FAV pressure gauge connection, carbon steel compatible with metric-threaded ports when using the 24Â° DIN 2353 socket and O-ring (FPM/FKM)?

No . the FAV pressure gauge connection, carbon steel Format described is not directly compatible with metric-threaded ports even though it uses a 24Â° DIN 2353 socket and Oâring (FPM/FKM). Explanation: the FAV coupling is specified as a DIN 2353 straight adjustable pressure coupling with an internal cylindrical BSP thread plus a 24Â° cone socket and Oâring that seals against the cone face. When fitted âwith internal metric thread, nutâ that denotes the coupling body accepts a metric-threaded component, but the sealing principle remains the 24Â° cone and Oâring system rather than a thread form seal. Direct mating to a port that expects a metric-threaded pipe seal (e.g. ISO metric threads that seal on threads or require a different cone angle) will not reliably seal unless the port is specifically machined to accept the DIN 24Â° cone and Oâring (or an appropriate adapter is used). Also verify series (L or S) and dimensions/material (carbon steel, galvanized) to ensure pressure rating and mechanical fit. For safe, leakâfree installation use a matching DIN 2353 24Â° port or a purpose-made adapter between metric-threaded port and the FAV connection.

Can the FAV pressure gauge connection, carbon steel be used with BSP internal cylindrical ports when fitted with the 24Â° DIN 2353 socket and FPM/FKM O-ring?

Yes. The FAV pressure gauge connection, carbon steel (DIN 2353 straight adjustable coupling, type FAV-B) can be used with BSP internal cylindrical ports when fitted with the 24Â° DIN 2353 socket and an FPM/FKM O-ring, provided the BSP port accepts a sealing ring arrangement and the mating dimensions conform. The FAV-B design uses a 24Â° cone socket plus an O-ring (FPM/FKM) and an internal cylindrical BSP thread with sealing ring; when assembled correctly (appropriate nut, internal metric thread engagement and correct O-ring material/size), it provides a reliable seal. Ensure series selection (L or S) matches pressure ratings and that materials (carbon steel, galvanized) and O-ring compatibility suit the fluid and temperature conditions.

Can the FAV pressure gauge connection, carbon steel be adapted between BSP and metric ports using the 24Â° socket with FKM/FPM O-ring?

Yes. the FAV pressure gauge connection, carbon steel can be adapted between BSP and metric ports using the 24Â° socket with an FKM/FPM Oâring. The DIN 2353 straight adjustable coupling type FAVâB is designed with an internal cylindrical BSP thread plus a 24Â° DIN 2353 socket sealed by an Oâring (FPM/FKM) and an internal metric thread with nut, which permits reliable interfacing of BSP threaded instruments to metric ports (and vice versa) when assembled per DIN 2353 practice. Ensure correct series (L or S) and material compatibility (carbon steel, galvanized), proper Oâring condition and size, correct torque on the nut, and that mating ports conform to DIN 2353 dimensions to maintain seal integrity and pressure ratings.
