Can the Hose Quick-Connect Socket, No Valve, Acetal, SMC Series DN 1.2 withstand continuous use at 6.9 bar and -40°C to +82°C without leakage?

Yes. The Hose Quick-Connect Socket, No Valve, Acetal, SMC Series DN 1.2 is specified for working pressures up to 6.9 bar and an operating temperature range of -40°C to +82°C. Made from durable acetal and designed with a secure twist-to-connect mechanism that prevents kinking, twisting, and accidental disconnection, it is engineered for continuous use within those pressure and temperature limits without leakage, provided it is installed and used according to manufacturer recommendations and compatible with the connected hose and media.

Is the Hose Quick-Connect Socket, No Valve, Acetal, SMC Series DN 1.2 compatible with common inkjet inks and cleaning solvents without material degradation?

Hose Quick-Connect Socket, No Valve, Acetal, SMC Series DN 1.2 is described as designed for demanding applications including inkjet printing systems and mentions compatibility with such environments. Manufactured from acetal (POM), it offers good chemical resistance to many common aqueous and solvent-based fluids, good dimensional stability across -40°C to +82°C, and durability at pressures up to 6.9 bar. This suggests it will generally tolerate typical inkjet inks and routine cleaning solvents without rapid degradation. However, acetal can be attacked or swollen by certain aggressive solvents (strong ketones like MEK, concentrated chlorinated hydrocarbons, and some aromatics) and by prolonged exposure to strong acids or bases. Very aggressive or high-temperature solvent exposure, or repeated harsh cleaning cycles, could reduce mechanical properties or cause stress cracking over time. Conclusion: For most common inkjet inks and typical cleaning solvents the Hose Quick-Connect Socket, No Valve, Acetal, SMC Series DN 1.2 should be compatible, but confirm chemical compatibility for specific ink and solvent formulations (especially ketones, strong aromatics or chlorinated solvents) and validate with supplier compatibility charts or testing for long-term use.

Additional information

Material	P – material (plastic)

The quick coupling socket with hose end, designed without a valve, is an advanced solution for demanding applications such as inkjet printing systems, medical blood handling, cooling circuits, and gas chromatography. Its innovative connection method, based on twisting two elements together, ensures a secure and reliable fit while allowing slight hose rotation to prevent kinking, twisting, or accidental disconnection. With a compact nominal size of DN 1.2 mm and total length L [mm], this coupling combines precision with convenience. Manufactured from durable acetal, it guarantees long-lasting performance under working pressures up to 6.9 bar and in a wide temperature range from -40°C to +82°C. For added versatility, the product line also includes versions with an integrated valve and in black color, offering tailored solutions for diverse technical requirements. This makes the coupling an ideal choice wherever safety, efficiency, and reliability are essential.
