Mueller Streamline W 01000 Coupling Rolled Stop C X C 1/8 in

Product Description

The MUELLER STREAMLINE w 01000 is a wrot copper rolled-stop coupling with a C x C (cup by cup) end configuration, sized at 1/8 inch OD. This fitting is designed for soldered-joint connections in pressurized supply piping systems. The rolled stop inside the fitting controls insertion depth, ensuring consistent joint geometry and reliable solder flow. Licensed plumbing contractors and pipefitters install this type of fitting in potable water supply lines where a straight inline connection is required. Compliance with multiple ASME and NSF standards confirms suitability for pressure service in above-ground installations.

This coupling is intended for above-ground potable water supply systems. Its compact 1/8 inch size makes it appropriate for small-diameter branch lines, instrumentation connections, and tight-space plumbing runs encountered in residential and light commercial work. The wrot copper construction offers the ductility and solderability that professionals expect when working with torch-applied solder-joint fittings in copper distribution systems.

Key Features

• Rolled internal stop controls insertion depth for consistent, repeatable solder joints
• Wrot copper construction provides high ductility and excellent solderability
• C x C end type accepts standard 1/8 inch copper tubing on both ends
• Rated for potable water service and meets NSF 61G requirements
• Manufactured to ASME B16.22 and additional applicable ASME solder-joint standards
• Suitable for above-ground pressurized supply systems

Compatibility

Designed as an OEM-style solder-joint replacement fitting for above-ground potable water supply systems using standard 1/8 inch OD copper tubing with cup-end connections.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IFGC or IPC requirements. Shut off and depressurize the water supply line completely before cutting or fitting. Clean and flux all mating copper surfaces before applying heat, and allow joints to cool fully before restoring pressure. Do not use this fitting in below-ground or direct-burial applications.
