1" x 100' Copper Tubing, Soft Coil, Type K

Streamline KS10100 – 1" x 100' Type K Copper Tubing (Soft Coil) Streamline KS10100 is a 100-foot soft coil of 1" nominal Type K copper tubing manufactured for use in underground and above-ground water supply systems, HVAC piping, and other applications requiring high-strength, corrosion-resistant copper. Type K features the thickest wall among the standard copper types (K, L, M, DWV), making it suitable for direct burial and high-pressure installations. This seamless tubing is supplied in a soft temper for flexibility and easier bending around obstacles, reducing the number of required fittings and joints. The tubing is color-coded green and incised marked for easy identification and specification verification on job sites. Product Features Type K Wall Thickness – Heaviest copper tube wall available for pressure and underground use Soft Temper Coil – Flexible configuration allows for continuous runs and minimal need for couplings Corrosion-Resistant – Suitable for potable water, hydronic heating, and HVAC systems System Compatibility – Designed for soldering, brazing, flaring, or compression connections Code-Compliant Identification – Marked in accordance with ASTM and applicable plumbing codes Specifications Nominal Size: 1 inch Outside Diameter (OD): 1.125 inches Wall Thickness: 0.065 inches (nominal) Length: 100 feet (coil) Material: Seamless copper tubing Type: K (Soft Temper) Temperature Range: 32°F to 400°F (typical operating limits) Standards Compliance: ASTM B88, NSF/ANSI 61 & 372, ASME B16.22, and UPC/IPC listed Applications Potable water supply Underground service lines Hydronic heating HVAC refrigerant and condensate lines Suitable for residential, commercial, and institutional use Installation Notes Type K soft copper should be installed per local code requirements and manufacturer guidance. Due to its soft temper, it may be bent manually or with a mechanical bender, and it supports long runs with fewer fittings. For underground installations, trench depth, bedding, and corrosion barriers (where required) must comply with code and soil condition assessments. Use with approved fittings and connection methods depending on the application—flared, soldered, or brazed connections are common. Pressure testing and proper support spacing are critical for system integrity.
