Is the Quick connector DN2.7 without valve, with hose socket, brass, series 20KA suitable for use with drinking water and potable systems?

Quick connector DN2.7 without valve, with hose socket, brass, series 20KA . based on the provided description, the coupling is designed for water, air, nitrogen and other nonâflammable gases, is made of brass, and operates from â20Â°C to +100Â°C at up to 35 bar. However, suitability for use with drinking water and potable systems depends on additional factors not stated in the description: - Materials compliance: potable water use requires brass that meets relevant drinkingâwater standards (e.g., EN 12164/12165, NSF/ANSI 61, WRAS, ACS or local approvals) and low lead content (<0.25% or countryâspecific limits). The description only lists âbrass,â without certification or alloy/lead content information. - Surface treatment and seals: any plating, coatings, or elastomer seals (if present) must be certified for potable water; no seal material or coating information is provided. - Cleanliness and manufacturing: foodâcontact manufacturing practices and traceability may be required for potable applications; not specified. Conclusion: Quick connector DN2.7 without valve, with hose socket, brass, series 20KA is described as suitable for water in general, but you cannot assume it is approved for drinking water systems. To confirm potable suitability, obtain from the manufacturer or supplier: material standards/certifications (NSF/ANSI 61, WRAS, ACS or local equivalents), alloy/lead content, details of any coatings and seal materials, and relevant test reports or declarations of conformity.

Can the Quick connector DN2.7 without valve, with hose socket, brass, series 20KA be used with compressed nitrogen at 35 bar?

Yes. Quick connector DN2.7 without valve, with hose socket, brass, series 20KA is specified for use with nitrogen and other non-flammable gases and has a working pressure of 35 bar. Its material (brass) and operating temperature range (â20Â°C to +100Â°C) support that application. Ensure hose and system components are rated for 35 bar and for nitrogen service, and follow applicable safety and regulatory procedures for compressed gas use.

Is the Quick connector DN2.7 without valve, with hose socket, brass, series 20KA compatible with food-grade hoses?

Quick connector DN2.7 without valve, with hose socket, brass, series 20KA. based on the provided description, compatibility with food-grade hoses cannot be guaranteed outright. Reasons: - Material: The connector body is brass. Standard brass often contains small amounts of lead or other alloying elements that may not meet food-contact regulations (e.g., FDA, EU 1935/2004, or NSF/ANSI 61). Only dezincification-resistant (DZR) or specifically food-grade brass alloys and appropriate surface treatments are acceptable for many food applications. - Seal/inner parts: The description does not specify the type or food-safety rating of any internal seals, O-rings or plating. These components are critical for food compatibility and must be made of approved materials such as EPDM, silicone, or FKM with food-grade certification. - Intended media: The product is stated as designed for water, air, nitrogen and other non-flammable gases, but that does not imply compliance with food-contact standards. - Temperature and pressure: Operating range (-20Â°C to +100Â°C, 35 bar) is suitable for many food processes, but regulatory compliance and material compatibility remain limiting factors. Recommendation: - Ask the manufacturer/supplier for documentation: alloy specification (lead content, DZR or food-grade designation), certification (FDA, EU 1935/2004, NSF/ANSI), and specification of all elastomers and surface platings. - If documentation is unavailable or the brass is standard (non-certified), do not assume compatibility; use a connector explicitly certified for food contact or made from approved materials (stainless steel 316, food-grade brass certified, and food-grade seals). Conclusion: Without explicit manufacturer certification of brass alloy and sealing materials for food contact, the Quick connector DN2.7 without valve, with hose socket, brass, series 20KA should be considered not confirmed for use with food-grade hoses.
