Is the DN11.8 Stainless Steel Water Quick Connector with Hose End, No Flange compatible with standard garden hoses and pressure washers up to 200 bar?

Yes. The DN11.8 Stainless Steel Water Quick Connector with Hose End, No Flange is compatible with standard high-pressure garden hoses and fittings used in professional cleaning systems, and it is rated for working pressures up to 200 bar. Made from AISI 303/304L stainless steel, it offers corrosion resistance and durability for demanding environments, a flange-free design for easy handling, and precise machining for a secure, leak-free connection. Its operating temperature up to +100°C and robust construction make it suitable for intensive cleaning tasks and pressure washer use within the specified pressure limit.

Does the DN11.8 Stainless Steel Water Quick Connector with Hose End, No Flange require specific O-rings or maintenance to maintain leak-free performance at 200 bar?

DN11.8 Stainless Steel Water Quick Connector with Hose End, No Flange — does it require specific O-rings or maintenance to maintain leak-free performance at 200 bar? Based on the product description, the coupling is precision-engineered for a secure, leak-free fit up to 200 bar and is made from corrosion-resistant AISI 303/304L stainless steel. However, to reliably maintain leak-free performance at high pressures you should: - Use the manufacturer's specified O-rings/materials: High-pressure sealing typically requires compatible, high-quality O-rings (e.g., NBR, EPDM, or FKM/Viton depending on water temperature and any chemicals). Verify the supplier’s recommendation for O-ring size and material to ensure pressure and temperature compatibility (up to +100°C). - Inspect and replace O-rings regularly: Check seals for wear, cuts, swelling or hardening and replace them at first signs of degradation. High-pressure cycling shortens seal life. - Maintain clean mating surfaces: Debris or corrosion on the connector or hose end can damage O-rings and cause leaks. Keep parts clean and free of grit. - Follow torque/assembly guidance: Ensure correct hose fitting and secure assembly without over-tightening which can damage seals. - Periodic pressure testing: After assembly or maintenance, perform a pressure test to confirm there are no leaks. While the product’s precision design supports leak-free operation at 200 bar, proper O-ring selection, routine inspection and standard maintenance are necessary to sustain that performance.
