Cerro Flow Products Llc 1537 Type M Hard Copper Tube

Product Description

The CERRO FLOW PRODUCTS LLC 1537 is a Type M hard drawn copper tube sized at 1/2 inch diameter in 5-foot lengths. Type M copper is the standard choice for residential water supply and distribution lines, offering a thinner wall profile than Type K or L while still meeting code requirements for most above-ground interior applications. Each length ships as part of a 10-piece package unit. Licensed plumbers and experienced DIYers install this tube for hot and cold water supply runs, replacement sections, and branch line extensions in residential systems.

This tube is suited for residential potable water distribution, baseboard heating supply lines, and general plumbing rough-in work. The hard drawn temper holds its shape without support over longer spans, making it practical for straight runs through framing and mechanical chases. It is not intended for underground burial or high-pressure commercial steam applications where Type K or L wall thickness is required by code.

Key Features

• Type M wall thickness meets ASTM B88 standards for residential above-ground water service
• Hard drawn temper maintains shape on straight runs without continuous support
• 1/2 inch diameter fits standard sweat, press, and push-to-connect fittings
• 5-foot length suitable for repair sections and short branch runs
• Sold in 10-piece packages (sold as individual unit per EA)

Compatibility

Designed as an OEM-style replacement and standard supply tube compatible with 1/2 inch copper sweat, press-fit, and push-to-connect fittings used in residential potable water and hydronic heating systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local amendments. Shut off the water supply and depressurize the line before cutting or joining. Use a proper pipe cutter and deburring tool to prepare tube ends before soldering, pressing, or connecting. Type M copper is not approved for underground or exterior buried service in all jurisdictions — verify local code before installation.
