Can the Quick connector DN10 without valve, threaded, hardened steel, 1800 series be used interchangeably with 1800N series couplings?

No . Quick connector DN10 without valve, threaded, hardened steel, 1800 series cannot be used interchangeably with 1800N series couplings. According to the product description, couplings from series 1800 should not be connected with series 1800N. Even though both series may share similar dimensions and a working pressure of 35 bar and materials (hardened zincâcoated steel or AISI 316), they are designed as incompatible families. To ensure safe, leakâfree operation for air and liquids, use only matching series parts.

Are Quick connector DN10 without valve, threaded, hardened steel, 1800 series compatible with different thread types (BSP, BSPT, internal BSP)?

Quick connector DN10 without valve, threaded, hardened steel, 1800 series: compatibility depends on thread type-plugs are available with external BSP, external BSPT or internal BSP threads. You must match male/female thread type exactly: external BSP mates with internal BSP; external BSPT requires a mating BSPT thread (tapered) and is not directly interchangeable with BSP (parallel) without proper adapters/sealing; internal BSP must be paired with external BSP. Additionally, do not connect 1800 series couplings with 1800N series. Materials (hardened zinc-coated steel or AISI 316) and 35 bar working pressure are common across the range.

Are Quick connector DN10 without valve, threaded, hardened steel, 1800 series suitable for use with liquids at 35 bar?

Yes. Quick connector DN10 without valve, threaded, hardened steel, 1800 series is suitable for use with liquids at 35 bar. Reasoning: the Universal quick coupling plug description for the TEMA 1800 series states the series is designed for air and liquids and lists a working pressure of 35 bar. The specified material (hardened zinc-coated steel or AISI 316 steel) is compatible with liquid service, and the connector is DN10 threaded as described. Note: ensure you do not connect 1800 series couplings with 1800N series couplings, and verify thread type (external BSP/BSPT or internal BSP) matches your system.
