Can the Hose quick connect plug, polypropylene, HFC series DN 12.7 be used with chemicals and pneumatic systems at up to 4.2 bar and 0â71Â°C without degradation of the EPDM O-ring?

Yes . the Hose quick connect plug, polypropylene, HFC series DN 12.7 can be used with chemicals and in pneumatic systems at up to 4.2 bar and 0â71Â°C without expected degradation of the EPDM O-ring, provided the chemicals are compatible with EPDM and polypropylene. The product specification lists EPDM sealing, a working pressure up to 4.2 bar, and an operating temperature range of 0â71Â°C, and it is intended for chemical and pneumatic installations and nonâfreezing liquids. Caveats: - Verify chemical compatibility: EPDM resists many polar solvents, water-based chemicals, glycols, and certain acids/alkalis but is attacked by many hydrocarbons, oils, ketones, and aromatics. Check the specific chemical(s) against EPDM and polypropylene compatibility charts. - Consider concentration, temperature, exposure time and any additives that can affect O-ring life. - For safety-critical or continuous-service applications, test under actual conditions or consult the manufacturer for confirmation. If you provide the exact chemicals and concentrations, I can advise more precisely.

Does the Hose quick connect plug, polypropylene, HFC series DN 12.7 allow slight hose rotation to prevent twisting and accidental disconnection?

Yes. The Hose quick connect plug, polypropylene, HFC series DN 12.7 allows slight rotation of the connected hose to prevent twisting and accidental disconnection, as stated in the product description.

Is the Hose quick connect plug, polypropylene, HFC series DN 12.7 compatible with non-freezing liquid sprayers and battery filling systems?

Yes. The Hose quick connect plug, polypropylene, HFC series DN 12.7 is compatible with non-freezing liquid sprayers and battery filling systems. The product description explicitly lists sprayers, battery and accumulator filling installations, and non-freezing liquids among its applications. Its polypropylene construction and EPDM O-ring sealing are suitable for many chemical and aqueous fluids, and the working pressure (up to 4.2 bar) and operating temperature range (0Â°C to +71Â°C) cover typical conditions for such systems. The efficient valve provides high flow and minimal leakage, and the design allows slight hose rotation to prevent twisting and accidental disconnection. beneficial for mobile sprayers and filling operations. Caveats: verify chemical compatibility of polypropylene and EPDM with the specific non-freezing fluid or battery electrolyte you use, and ensure your system operates within the stated pressure and temperature limits.

Additional information

Material	P – material (plastic)

Quick coupling plug with hose end, with valve and without shut-off valve, intended for water, chemical, pneumatic installations, etc. Compared to traditional massive couplings with balls and securing sleeve, it has a very low weight. The highly efficient valve allows for high flow rates and minimal leakage. This coupling also allows for slight rotations of the connected hose, preventing twisting and accidental disconnection of the coupling. Applications: chemical photographic processes, battery and accumulator filling installations, sprayers, pneumatic installations, and non-freezing liquids, etc. Length L [mm] – total length. Material: polypropylene. Sealing: EPDM o-ring. Working pressure: up to 4.2 bar. Operating temperature: from 0°C to +71°C.
