Is the M16x2 Measuring Connector with Cap, BSP Male & Female Threads compatible with both steel and plastic caps for temps up to +120°C?

The M16x2 Measuring Connector with Cap, BSP Male & Female Threads is compatible with both steel and plastic caps, but with a temperature limitation: steel (metal) caps allow the full operating range up to +120°C, while the plastic cap is rated up to +100°C. Both cap options meet ISO 15171-2 design requirements and provide secure, leak-free installation with NBR sealing, but for applications approaching +120°C choose the durable metal cap.

Can the M16x2 Measuring Connector with Cap, BSP Male & Female Threads be used with different seal materials (e.g., Viton) for higher chemical resistance or temperature ranges?

Yes. The M16x2 Measuring Connector with Cap, BSP Male & Female Threads can accommodate alternative seal materials such as Viton (FKM) to achieve higher chemical resistance and extended temperature capability, but with some caveats: - Compatibility: The standard unit is supplied with NBR seals (–30°C to +120°C; up to +100°C with the plastic cap). Replacing NBR with Viton will increase resistance to many aggressive fluids and push the upper continuous temperature limit (Viton typically usable to ~+200°C depending on compound). - Pressure & performance: Changing the seal material does not alter the mechanical design or pressure ratings (345–400 bar depending on size). Ensure the chosen Viton compound maintains sealing elasticity and compression set properties at your operating pressure and temperature. - Cap temperature constraint: If you use the plastic cap, its maximum temperature (typically +100°C) may become the limiting factor even if the Viton seal permits higher temperatures. For high-temperature use prefer the metal cap. - Certification & standards: The device is designed to ISO 15171-2; any seal change should be validated to ensure continued compliance and leak-free performance in your specific application. - Recommendation: Specify the required chemical exposure and temperature range to the supplier and request compatible Viton (or other elastomer) seals and validation testing. For highest temps and aggressive media, use metal cap and confirm material compatibility and pressure/temperature ratings with manufacturer.
