Is the Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass suitable for steam applications at +150Â°C with EPDM seals?

Yes. Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass is listed for steam service and, with EPDM seals, has an operating temperature range up to +150Â°C.so it is suitable for steam at +150Â°C. Ensure the pressure at that temperature does not exceed the specified working pressure for the chosen size (50/30/20/15 bar depending on coupling size) and confirm compatibility of EPDM with your specific steam chemistry and cycle conditions (e.g., continuous live steam, condensate, or additives).

Can the Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass be used with hydraulic oil at 50 bar and +120Â°C?

No. The Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass is rated for hydraulic oil pressure up to 50 bar (for sizes 1/8", 1/4", 3/8") but its standard operating temperature range depends on seal material: NBR up to +80Â°C, Viton up to +180Â°C, EPDM up to +150Â°C. At +120Â°C you must ensure the coupling uses Viton or EPDM seals (NBR is not acceptable). Also confirm your coupling size is one of the 50âbar rated sizes and check chemical compatibility of the specific hydraulic oil with brass and the chosen seal. If any of these conditions are not met, do not use at 50 bar and +120Â°C.

Can the Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass withstand continuous use at 50 bar?

Yes. provided you use the correct size and appropriate seal material, the Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass can withstand continuous use at 50 bar. Key points: - Rated working pressure: 50 bar for sizes 1/8", 1/4", and 3/8". these sizes are specified for 50 bar continuous operation. - Larger sizes have lower ratings (30, 20, 15 bar) and must not be used at 50 bar. - Temperature and seal compatibility: ensure the chosen seal material (NBR, Viton, or EPDM) suits your fluid and operating temperature range (NBR: -20Â°C to +80Â°C; Viton: -20Â°C to +180Â°C; EPDM: -40Â°C to +150Â°C). - Media compatibility: unit is designed for water, hydraulic oils, steam, chemicals, air, and gases. confirm chemical compatibility with the seal and brass. Conclusion: For continuous operation at 50 bar, select a 1/8", 1/4", or 3/8" Quick coupling plug with GW BSPT valve, NITTO KOHKI SP CUPLA type A, brass, and use seals and temperatures within the specified limits.
