Can the Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 withstand continuous operation at 6.9 bar and temperatures up to +82Â°C without material degradation?

Based on the provided specification, the Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 is rated for working pressure up to 6.9 bar and an operating temperature range of 0Â°C to +82Â°C. If your application operates continuously at 6.9 bar and temperatures up to +82Â°C, these nominal limits indicate the part is designed to handle those conditions. However, a few caveats before confirming long-term suitability: - Continuous operation at the maximum rated pressure and temperature can accelerate polymer aging, stress relaxation and creep; polypropyleneâs mechanical properties degrade faster near its upper temperature limit. - Chemical compatibility with the actual fluids (inks, cooling fluids, blood, gases, solvents) and any additives or cleaning agents must be confirmed for polypropylene to avoid swelling, embrittlement or stress cracking. - Repeated twisting/rotation cycles and system vibration may introduce fatigue; verify cycle-life data if frequent coupling/uncoupling or hose movement is expected. - Safety margin: designing with some margin below maximum ratings (e.g., operating at â¤80â90% of 6.9 bar and slightly below +82Â°C) improves reliability. Conclusion: According to the stated ratings, the Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 can operate continuously at 6.9 bar and up to +82Â°C, but for long-term reliability you should verify chemical compatibility, mechanical fatigue/cycle-life data and consider operating with margin below the maximum ratings.

Is the Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 compatible with common inkjet inks and cleaning solvents?

Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 is likely compatible with many common inkjet inks and typical cleaning solvents, because polypropylene has good chemical resistance to a wide range of aqueous, pigment and dye-based inks and many polar/nonâpolar solvents. However compatibility depends on specific ink/solvent chemistry (e.g., strong ketones, chlorinated solvents, concentrated acids/alkalis or aggressive solvents may degrade polypropylene) and on operating conditions (temperature up to +82Â°C, pressure up to 6.9 bar). Recommend checking the exact ink/solvent MSDS and performing a compatibility test or consulting the ink supplier to confirm longâterm resistance before use.

Does the Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 allow slight hose rotation to prevent twisting and disconnection?

Yes. The Hose quick-connection socket, without valve, polypropylene, SMC series DN 1,2 allows slight rotation of the connected hose to prevent twisting and accidental disconnection. The couplingâs design involves twisting two parts relative to each other and specifically permits limited hose rotation while maintaining a secure connection. Specifications: nominal size DN 1.2 mm, material polypropylene, working pressure up to 6.9 bar, operating temperature 0Â°C to +82Â°C.
