Does the MAV pressure gauge straight fitting, carbon steel, zinc-nickel, meet DIN 2353 corrosion resistance (720h salt spray) and which series (L or S) is recommended for high-pressure systems?

Yes. The MAV pressure gauge straight fitting, carbon steel, zinc-nickel meets DIN 2353 corrosion resistance: its zinc-nickel coating (6â10 Âµm) is rated for very high corrosion resistance . up to 720 hours in a salt spray chamber, which aligns with the DIN 2353 requirement. For high-pressure systems the S (heavy) series is recommended, as the S series is designed for heavier-duty/high-pressure applications, while the L (light) series is intended for lower-pressure uses.

Is the MAV pressure gauge straight fitting, carbon steel, zinc-nickel, compatible with BSP internal threads and 24Â° DIN 2353 metric external threads?

Yes. The MAV pressure gauge straight fitting, carbon steel, zinc-nickel Format features an internal cylindrical BSP thread with sealing ring and a 24Â° DIN 2353 socket with external metric thread, so it is compatible with BSP internal threads on the gauge side and 24Â° DIN 2353 external metric threads on the mating connector. Surface zincânickel coating (6â10 Âµm) and carbon steel construction apply.

Can the MAV pressure gauge straight fitting, carbon steel, zinc-nickel, be used with hydraulic fluids at elevated temperatures?

Possibly, but with limitations. not recommended without verification. Explanation: - MAV pressure gauge straight fitting, carbon steel, zinc-nickel, is a DIN 2353 straight pressure gauge fitting (type MAV-B) with carbon steel body and a zinc-nickel coating (6â10 Âµm) that provides excellent corrosion resistance. - The description specifies mechanical/threaded details and corrosion protection but does not state operating temperature limits or compatibility with hydraulic fluids at elevated temperatures. - Carbon steel base metal can generally withstand moderate elevated temperatures, but the performance and chemical compatibility depend on the specific hydraulic fluid, exact temperature, pressure, and exposure time. - The zinc-nickel plating offers corrosion resistance but can degrade or change characteristics at higher temperatures; some coatings may soften, oxidize, or lose adhesion above certain temperatures (varies by process and specification). - Sealing depends on the sealing ring material (unspecified). Elastomeric seals (e.g., NBR, FKM, EPDM) have temperature limits and fluid compatibility that are critical for safe use at elevated temperatures. Recommendation: - Do not assume suitability. Verify with the manufacturer or technical datasheet for: - Maximum continuous temperature rating for the fitting and coating - Compatibility of the zinc-nickel finish with the specific hydraulic fluid at the intended temperature - Type and temperature rating of the sealing ring used in MAV pressure gauge straight fitting, carbon steel, zinc-nickel - Pressure rating at the elevated temperature - If manufacturer data are unavailable, consider selecting fittings and seals explicitly rated for the hydraulic fluid and temperature range (e.g., high-temperature hydraulic fittings and high-temp elastomers) or conduct testing under controlled conditions.
