Heavy-wall seamless copper tubing in a 60-foot soft annealed coil. Type K is the thickest-walled copper water tube and is the preferred choice for underground water service lines, where its extra wall thickness resists corrosion and physical stress better than Type L or M.

• Outside diameter: 1/2"
• Length: 60 Ft soft annealed coil
• ASTM B88 Type K specification
• 99.9% pure copper (UNS C12200)
• Thickest wall of the three plumbing types (K/L/M)
• Suitable for buried water service and high-pressure applications
• Joins by sweat solder, flare, or compression fittings

Tip: Bend gradually around a forming spring or a tube bender to avoid kinks; once kinked, the section should be cut out.
