Rated at 125 psi WOG (water, oil, gas), it handles typical residential and light commercial plumbing service pressures with a maximum working temperature of 180 degrees F. The all-brass construction resists corrosion and provides reliable long-term sealing performance. Licensed plumbers and experienced pipefitters install this fitting in water supply, hydronic, and low-pressure gas distribution systems where a compression-style mechanical connection is preferred or required.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for repair and retrofit work in residential and light commercial plumbing systems. It is commonly used where copper tube runs transition between nominal pipe sizes, or where a solder-free connection is needed due to proximity to finished surfaces, live systems, or other heat-sensitive conditions. The compression design allows installation in tight spaces and supports future disassembly when service access is needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction for corrosion resistance and durability in wet service\u003c\/li\u003e\n\u003cli\u003e125 psi WOG pressure rating suitable for water, oil, and gas applications\u003c\/li\u003e\n\u003cli\u003eMaximum working temperature of 180 degrees F\u003c\/li\u003e\n\u003cli\u003eCompression fitting design requires no soldering or open flame\u003c\/li\u003e\n\u003cli\u003eConnects 1\/2 inch pipe to 3\/4 inch copper tube in a single fitting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4 inch copper tube and 1\/2 inch nominal pipe in standard residential and light commercial plumbing installations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber following applicable IPC and local plumbing code requirements. Shut off the water supply and relieve system pressure before making or breaking any compression fitting connection. Hand-tighten the compression nut first, then use an appropriately sized wrench to seat the ferrule — avoid over-tightening, which can deform the ferrule and cause leaks. Inspect for leaks at operating pressure before closing up the work area.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCopper Tube Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Size\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating (WOG)\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.713 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LEGEND VALVE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 303-124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51542447522098,"sku":"303-124","price":28.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1e999d1ed6dcd33dd6a92c78c98012f.jpg?v=1785900814","url":"https:\/\/voomisupply.com\/products\/legend-valve-303-124-brass-compression-pipe-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
