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

Yes. The Straight reduction plug connector, type PUCM is specified for a working pressure of 10 bar and an operating temperature range of 0Â°C to +60Â°C with NBR (nitrile) sealing. Under those declared conditions . continuous operation at 10 bar and temperatures up to +60Â°C . the connector and its NBR seal are within their rated limits and should not experience seal degradation if used as specified. Caveats: ensure installation and hose dimensions match the productâs calibrated metric diameters, avoid exposure to chemicals, oils, ozone or UV beyond NBR compatibility, and prevent mechanical stress or temperature/pressure spikes above the stated limits, as those factors can shorten seal life. For critical or safetyâcritical applications, perform applicationâspecific validation or consult the manufacturer.

Is the Straight reduction plug connector, type PUCM compatible with NBR seals for occasional vacuum use down to 0.01 bar?

Yes. Straight reduction plug connector, type PUCM is compatible with NBR seals for occasional vacuum use down to 0.01 bar. The product specification lists Vacuum: 0.99 bar (which corresponds to a maximum achievable vacuum of 0.01 bar absolute), and Sealing: NBR, so NBR seals are suitable for occasional use at that vacuum level. Ensure operating temperature and chemical exposure remain within the listed limits (0Â°C to +60Â°C) for reliable sealing.

Does the Straight reduction plug connector, type PUCM resist chemical exposure from common pneumatic oils and lubricants?

Straight reduction plug connector, type PUCM is made of plastic with NBR (nitrile rubber) seals. NBR is widely used for resistance to oils, greases and many common pneumatic lubricants. Within the stated operating conditions (working pressure up to 10 bar, temperature range 0Â°C to +60Â°C) the connector and its NBR sealing will generally resist exposure to common pneumatic oils and lubricants used in industrial and workshop environments. However, compatibility depends on the specific oil/lubricant chemistry (e.g., mineral oils vs. synthetic esters, silicone oils, phosphate esters, ketones or strong solvents) and concentration, temperature and exposure duration. Aggressive chemicals, strong solvents or prolonged contact at elevated temperature can degrade plastic parts or NBR seals and reduce service life or cause failure. Recommendation: verify the exact lubricant formulation against NBR compatibility charts and, if possible, perform a short-term compatibility test under expected pressure, temperature and exposure conditions. If compatibility with aggressive or synthetic fluids is required, consider alternative seal materials (e.g., FKM/Viton) or consult the manufacturer for validated fluid compatibility.
