Macomb Group Approved 100CKC60 Type K Soft Copper Coil Tube

Product Description

The MACOMB GROUP APPROVED 100CKC60 is a Type K soft (annealed) seamless copper water tube supplied in a 60-foot coil. Type K carries the heaviest wall thickness of the standard copper tube classifications, making it the preferred choice for underground service lines, high-pressure domestic water systems, and applications where added wall strength is required. This coil measures 1 inch nominal size with an outside diameter of 1.125 inches, an inside diameter of 0.995 inches, and a wall thickness of 0.065 inches. The soft-temper annealing allows the tube to be bent and routed without fittings in many field situations, reducing labor and potential leak points.

This tube is used in residential and light commercial plumbing for cold and hot water supply, underground water service entry, radiant heating systems, and fuel gas distribution where Type K copper is code-approved. The 60-foot coil format suits long runs with minimal joints. Plumbers and mechanical contractors specify Type K soft copper when working with buried or concealed runs where flexibility and pressure rating both matter. The 0.778 square-inch bore cross-sectional area supports strong flow capacity at the 1-inch nominal size.

Key Features

• Type K heavy wall construction - 0.065-inch wall thickness for maximum pressure rating among standard copper tube types
• Rated to 327 psi maximum working pressure
• Soft-annealed temper allows field bending without a fitting at every direction change
• Meets ASTM B88 material standard and UNS C12200 copper alloy specification
• NSF/ANSI Standard 61 certified for potable water contact
• Supplied as a 60-foot coil - reduces joint count on long or buried runs

Compatibility

Designed for use in potable water supply, hydronic, and fuel gas piping systems where Type K seamless copper tube meeting ASTM B88 and NSF/ANSI 61 is specified. Compatible with standard sweat, compression, and press-style fittings dimensioned for 1-inch Type K copper tube.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local plumbing code requirements. Shut off the water supply and depressurize the line before cutting or joining. Use appropriate copper tube cutters and reamers to ensure clean, burr-free ends before soldering, brazing, or making mechanical connections. For underground burial, follow local code requirements for bedding material and minimum cover depth.
