Streamline KS20040 – 2" Type K Soft Copper Coil, 40 Ft
The Streamline KS20040 is a 2-inch nominal diameter, Type K soft copper tube coil, supplied in a 40-foot length. Manufactured for use in potable water systems, HVAC applications, and underground service lines, this tubing meets stringent performance standards for strength, corrosion resistance, and longevity in demanding environments.
Type K copper tubing features the thickest wall of all common copper types, offering high internal pressure capacity and excellent protection against external damage, making it the preferred grade for buried or heavy-duty service.

Professional Application Notes
Type K soft copper is commonly specified for underground water services and distribution lines, fire protection, and large-diameter commercial plumbing systems.
Soft coils reduce the need for elbows and mechanical joints, which simplifies installation and reduces potential leak points.
Proper support and expansion spacing should be accounted for during above-ground installations.
