• ASTM B88 Type L; medium wall, thinner than Type K and thicker than Type M
• Rated working pressure: 775 PSIG at 150 deg F and 729 PSIG at 200 deg F, JMF's published rating for tube in the annealed condition, which is the condition this soft coil is supplied in
• C12200 phosphorus-deoxidized copper, 99.9% minimum copper content
• Conforms to NSF/ANSI 61 Annex G, the third-party drinking water certification JMF publishes for its Type K, L and M water tube; evaluated by Underwriters Laboratories for drinking water supplies of pH 6.5 and above
• Common uses include appliance and ice maker hookups, fuel and fuel oil lines, gauge and instrument lines, and short HVAC and hydronic runs
• Joins by sweat solder, flare or compression fittings
• Manufacturer part: 6362404869802

Tip: Ream the inside of cut ends to remove the burr that restricts flow and causes turbulence noise. Water supplies below pH 6.5 may need corrosion control to limit copper leaching.
