Can the Straight plug connector, metric version, type PUCM withstand continuous operation at 10 bar and temperatures up to +60Â°C without seal degradation?

Yes. The Straight plug connector, metric version, type PUCM is specified for a working pressure of 10 bar and an operating temperature range from 0Â°C to +60Â°C, with NBR (Nitrile Rubber) seals. Operating continuously at 10 bar and up to +60Â°C falls within the stated limits, so under normal conditions and correct installation the seal should not degrade prematurely. Caveats: long-term durability depends on factors not given in the brief.chemical exposure (oils, solvents, aggressive gases), mechanical abrasion, dynamic movement, cyclic pressure/temperature fluctuations, and installation quality can all affect NBR life. NBR performs well with oils and general pneumatic media but has limited resistance to certain chemicals and higher temperatures (>60Â°C). For aggressive media or frequent thermal/pressure cycling consider higher-spec materials or consult the manufacturer.

Is Straight plug connector, metric version, type PUCM suitable for use with aggressive fluids that could degrade the NBR sealing?

No. Straight plug connector, metric version, type PUCM is sealed with NBR (nitrile rubber), which is not resistant to many aggressive fluids (strong acids, alkalis, aromatic hydrocarbons, ketones, ester-based solvents and some oils). The connectorâs plastic body and NBR sealing, plus operating temp 0â60Â°C, make it unsuitable for applications where such aggressive chemicals are present. For aggressive fluids choose a connector with a chemically resistant sealing (e.g., FKM/Viton, EPDM, PTFE) and compatible housing materials; verify chemical compatibility and operating conditions before use.

Can Straight plug connector, metric version, type PUCM be used for vacuum applications down to 0.01 bar?

Straight plug connector, metric version, type PUCM Format cannot be used for vacuum applications down to 0.01 bar. The product specification lists Vacuum: 0.99 bar, which means it is rated to withstand only a slight vacuum (approximately 0.01 bar absolute pressure drop from atmospheric pressure is not supported). For a vacuum level of 0.01 bar absolute (â99.99% vacuum), this connector is unsuitable. Additionally, the material (plastic) and NBR sealing are not specified for high vacuum service or deep vacuum compatibility. Use a connector explicitly rated for the required absolute pressure (0.01 bar) and for vacuum service materials and seals.
