It provides a secure, leak-resistant connection between an oxygen cylinder regulator and the downstream system. Constructed from brass, this nipple meets CGA-540 fitting standards and installs hand-tight, requiring no tools for make-up. At 2.5 inches in length with a 1\/4 inch NPT thread, it is a compact, purpose-built component used by welding professionals, medical gas technicians, and industrial gas service personnel working with high-pressure oxygen regulators.\u003c\/p\u003e\n\u003cp\u003eThis inlet nipple is suited for use in industrial, laboratory, and medical oxygen gas systems wherever a CGA-540 regulator connection is required. It is commonly installed during regulator service, cylinder changeouts, or system assembly where a fresh or replacement inlet fitting is needed. The hand-tight design speeds up routine connections and disconnections in high-turnover service environments. Sold individually, it is appropriate for bench stock or field replacement kits maintained by gas equipment service technicians.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCGA-540 fitting standard for oxygen cylinder regulator connections\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch NPT thread for compatibility with standard regulator inlet ports\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in oxygen service environments\u003c\/li\u003e\n  \u003cli\u003eHand-tight installation eliminates the need for wrench make-up\u003c\/li\u003e\n  \u003cli\u003e2.5 inch length suits standard regulator inlet configurations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.1 pounds, suitable for field and bench stock kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement inlet nipple for oxygen regulators using CGA-540 cylinder connections with 1\/4 inch NPT inlet porting.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified gas equipment technician familiar with high-pressure oxygen system safety. Always confirm the cylinder valve is fully closed and the system is fully depressurized before removing or installing any regulator fitting. Oxygen service fittings must be kept free of oil, grease, and hydrocarbon contamination at all times, as these substances present a serious ignition hazard in oxygen-enriched environments. Follow applicable Compressed Gas Association guidelines and any local codes governing oxygen cylinder handling and regulator service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCGA Fitting\u003c\/strong\u003e: CGA-540\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Hand Tight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Service\u003c\/strong\u003e: Oxygen\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 698944071752\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTERN ENTERPRISES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTERN ENTERPRISES","offers":[{"title":"Default Title","offer_id":51346818597170,"sku":"663","price":342.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310546410.jpg?v=1782091365","url":"https:\/\/voomisupply.com\/products\/western-enterprises-663-oxygen-regulator-inlet-nipple-1-4-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
