Is the 90° Quick Connect Hose Plug with Valve, Acetal, PLC Series DN 6.3 compatible with standard 6.3 mm hoses and fittings?

Yes. The 90° Quick Connect Hose Plug with Valve, Acetal, PLC Series DN 6.3 is compatible with standard 6.3 mm hoses and fittings. Its DN 6.3 designation indicates it is sized for 6.3 mm inner-diameter hose connections, and the hose-end quick-connect design ensures a precise, secure fit. Constructed from durable acetal with an NBR O-ring, it provides reliable sealing and leak prevention while handling up to 8.3 bar and temperatures from −40 °C to +82 °C—suitable for typical washing systems, deionized water filtration, industrial machinery, and leak detection applications.

Can the 90° Quick Connect Hose Plug with Valve, Acetal, PLC Series DN 6.3 be used with deionized water systems without causing material degradation or leaching?

The 90° Quick Connect Hose Plug with Valve, Acetal, PLC Series DN 6.3 is manufactured from acetal (POM) with an NBR (nitrile) O‑ring and is rated for typical wash, filtration and deionized water applications. Acetal offers good mechanical strength, low water absorption and good chemical resistance to pure water; NBR provides reliable sealing but is more susceptible to swelling or degradation in very pure or aggressive chemistries. For deionized (DI) water systems: - Acetal: generally compatible with DI water and unlikely to undergo rapid hydrolytic degradation or significant leaching under normal temperatures (−40°C to +82°C) and pressures (up to 8.3 bar). Long‑term exposure to ultra‑pure water can, however, slowly extract residual monomers or additives and slightly increase leaching compared with potable water. - NBR O‑ring: acceptable for many DI water uses but less ideal than EPDM or FFKM for ultra‑pure or high‑temperature DI systems; prolonged contact with very low‑ion water can lead to some extractables and reduced seal life. Conclusion: The 90° Quick Connect Hose Plug with Valve, Acetal, PLC Series DN 6.3 is suitable for typical deionized water applications, but for ultra‑pure, semiconductor‑grade, or extremely long‑term DI service where minimal leachables are critical, consider materials specifically specified for ultrapure water (e.g., acetal grades certified for DI use, EPDM/FFKM seals) and confirm manufacturer’s extractables/certifications. If in doubt, request material data sheets and compatibility testing.
