ICS Industries Type L Copper Coil 100 FT
Type L copper coils from ICS Industries are designed for water supply lines with 3/4″ nominal size and 7/8″ OD. They are noted for good quality copper tubing and compliance with NSF/ANSI Standard 61 for drinking water components, plus AB1953 and Vermont Act 193. Best for: traditional residential and light commercial plumbing where standard drinking-water-grade copper is required. Limitation: length is fixed at 100 feet, which may require splicing for longer runs. This coil is a solid baseline choice for standard copper installations.
ICS Industries Type K Copper Coil 60 FT
Type K copper coils offer robust piping for water distribution, with the same compliance notes as Type L. This coil is 60 feet long, making it ideal for shorter segments or compact installations where higher wall thickness is beneficial. Best for: projects needing extra durability in tighter runs. Limitation: shorter length means more joints for longer layouts; plan connections accordingly.
ICS Industries Type M Copper Coil 5 FT
Type M is a thinner-wall copper tubing option within ICS Industries’ lineup. This 5-foot length is best for very short connections or as a starter segment in custom builds. Best for: tight spaces where short copper runs are needed. Limitation: not suitable for longer runs without additional segments and fittings; may require more connections and potential leak points.
SharkBite 3/4 Inch x 100 Feet White PEX-B
This SharkBite PEX-B pipe coil offers 3/4 inch diameter in white PEX-B. It supports flexible plumbing with push-to-connect fittings and resistance to UV exposure for limited outdoor use. Best for: projects seeking faster installation with fewer connections and flexible routing. Limitation: not copper; if your goal is copper-specific performance or regulatory compatibility, choose copper instead or verify local code allowances for PEX in potable systems.
SUPPLYGIANT Oxygen Barrier PEX-B 100 FT
Oxygen barrier PEX-B tubing is used in radiant heating and hydronic systems to prevent oxygen ingress. The 100-foot coil is UV-resistant and freeze-resistant, making it suitable for indoor and outdoor installations. Best for: closed-loop heating systems and radiant floors where metal corrosion protection matters. Limitation: PEX-B is not copper; evaluate compatibility with your system and local codes when working with drinking water or potable uses.
Buying Guide
- Material needs: Choose copper when you require proven durability for drinking water and standard plumbing. Choose PEX when flexibility and faster installation are priorities.
- Length and fittings: Longer runs require fewer joints. If your layout requires multiple directions, plan for extra fittings and connectors.
- Code compliance: Verify NSF/ANSI 61 and local AB1953 or equivalent regulations for drinking water components. Copper often has straightforward code alignment, while PEX may have separate code considerations.
- Application: For radiant heating and hydronic systems, consider oxygen barrier PEX-B to limit corrosion in metal components.
- Ease of installation: PEX options typically offer faster, tool-free connections, while copper may demand torches, flux, and skilled soldering.
FAQ
- What is the difference between Type L, K, and M copper tubing? – Type L is a balance of strength and thinness for general plumbing, Type K is thicker and more durable for heavier applications, and Type M is thinner and used where higher-cost-saving options are acceptable for shorter runs.
- Is PEX-B suitable for potable water? – PEX-B is widely used for potable water; ensure the specific product complies with local plumbing codes and NSF/ANSI standards.
- Can I mix copper and PEX in a single system? – Yes, with the correct adaptors and fittings. Check local codes and ensure compatibility with your application.
- How do I determine the right length? – Measure the total run length, add a buffer for fittings and seasonal adjustments, and account for future expansion where possible.
- Are oxygen barrier PEX-B pipes better for heating systems? – They help prevent oxygen ingress, reducing corrosion in boilers and radiators, which is beneficial in closed-loop heating.
- Should I buy a longer coil to minimize joints? – Longer coils reduce the number of joints but may be harder to handle; balance length with ease of installation and available workspace.
